Mounting cautions  
Cautions to observe when mounting temperature increases  
in the relay are greatly dependent on the way different parts  
are located a PC board and the heating method of the reflow  
device. Therefore, please conduct testing on the actual  
device beforehand after making sure the parts soldered on  
the relay terminals and the top of the relay case are within the  
temperature conditions.

Measuring position of temperature profile  
Note
:
The soldering temperature profile  
indicates the pad temperature. In  
some cases, the ambient  
Note  
temperature may be greatly  
increased. Check for the specific  
mounting condition.  
Other things to observe  
• Exceeding the stipulated conditions when soldering may  
affect coaxial switch performance. Be sure to consult us  
beforehand.  
• Creep-up, wettability and solder strength will differ depending  
on changes in the mounting conditions and type of solder.  
Please evaluate based on actual production conditions.  
• Only apply coating after the relay has returned to room  
temperature.  
• Since thermal stress on a relay will depend on the PC board  
and process conditions, please be sure to test using the  
actual PC board.

GUIDELINES FOR USAGE  
For cautions for use, please read “GUIDELINES FOR MICROWAVE DEVICES USAGE” and “GUIDELINES FOR  
REL
A
Y
U
SAGE”  
Cautions for usage of RJ relays  
Latching  
External magnetic field  
• We recommend latching type when using in applications  
which involve lengthy duty cycles.  
• Since RJ relays are highly sensitive polarized relays, their  
characteristics will be affected by a strong external magnetic  
field. Avoid using the relay under that condition.  
• Regarding the set and reset pulse time, for the purpose of  
reliable operation under ambient temperature fluctuations  
and different operating conditions, we recommend setting the  
coil applied set and reset pulse time to 20 ms or more at the  
rated coil voltage.  
• The latching type relay is shipped in the reset position.  
But jolts during transport or impacts during installation can  
change the reset position. It is, therefore, advisable to build a  
circuit in which the relay can be initialized (set and reset) just  
after turning on the power.  
CONDITIONS FOR USE  
Conditions for use, transport and storage conditions  
During usage, storage, or transportation, avoid locations subject to direct sunlight and maintain normal temperature, humidity, and  
pressure conditions.  
T
e
mperature and humidity  
When transporting or storing relays while they are tube  
packaged, there are cases when the temperature may differ  
from the allowable range. In this situation, be sure to consult  
the individual specifications.  
The humidity range varies with the temperature. Use within  
the range indicated in the graph. (The allowable temperature  
depends on the relays.)

Precautions for Coil Input  
Long term current carrying  
Maximum allowable voltage and temperature rise  
Proper usage requires that the rated coil voltage be impressed on the  
coil. Note, however, that if a voltage greater than or equal to the  
maximum continuous voltage is impressed on the coil, the coil may  
burn or its layers short due to the temperature rise. Furthermore, do  
not exceed the usable ambient temperature range listed in the catalog.  
Maximum allowable voltage for coil  
A circuit that will be carrying a current continuously for long periods  
without relay or microwave device switching operation. (circuits for  
emergency lamps, alarm devices and error inspection that, for  
example, revert only during malfunction and output warnings with form  
B contacts)
 
Continuous, long-term current to the coil will facilitate  
deterioration of coil insulation and characteristics due to heating of the  
coil itself.  
In addition to being a requirement for relay operation stability, the  
maximum continuous impressed coil voltage is an important constraint  
for the prevention of such problems as thermal deterioration or  
For circuits such as these, please use a magnetic-hold type latching  
relay. If you need to use a single stable relay, use a sealed type relay  
that is not easily affected by ambient conditions and make a failsafe  
circuit design that considers the possibility of contact failure or  
disconnection.  
deformity of the insulation material, or the occurrence of fire hazards.  
Operate voltage change due to coil temperature rise  
(Hot start)  
ꢀ
ꢀ
In DC relays, after continuous passage of current in the coil, if the  
current is turned OF
F
,
t
hen immediately turned ON again, due to the  
temperature rise in the coil, the operate voltage will become somewhat  
higher. Also, it will be the same as using it in a higher temperature  
atmosphere. The resistance/temperature relationship for copper wire  
is about 0.4% for 1 °C, and with this ratio the coil resistance increases.  
That is, in order to operate of the relay, it is necessary that the voltage  
be higher than the operate voltage and the operate voltage rises in  
accordance with the increase in the resistance value. However, for  
some polarized relays, this rate of change is considerably smaller.  
DC Coil operating power  
Steady state DC current should be applied to the coil. The wave form  
should be rectangular. If it includes ripple, the ripple factor should be  
less than 5%.  
However, please check with the actual circuit since the electrical  
characteristics may vary. The rated coil voltage should be applied to  
the coil and the set/reset pulse time of latching type relay differs for  
each relays, please refer to the relay’s individual specifications.  
Coil connection  
When connecting coils of polarized relays, please check coil polarity  
(+,-) at the internal connection diagram (Schematic). If any wrong  
connection is made, it may cause
 
unexpected malfunction, like  
abnormal heat, fire and so on, and circuit do not work. Avoid  
impressing voltages to the set coil and reset coil at the same time.  
Ambient Environment  
Dew condensation  
Low temperature and low humidity  
Condensation occurs when the ambient temperature drops suddenly  
from a high temperature and humidity, or the relay and microwave  
device is suddenly transferred from a low ambient temperature to a  
high temperature and humidity. Condensation causes the failures like  
insulation deterioration, wire disconnection and rust etc.  
Panasonic Industry Co., Ltd. does not guarantee the failures caused  
by condensation.  
The plastic becomes brittle if the switch is exposed to a low  
temperature, low humidity environment for long periods of time.  
High temperature and high humidity  
Storage for extended periods of time (including transportation periods)  
at high temperature or high humidity levels or in atmospheres with  
organic gases or sulfide gases may cause a sulfide film or oxide film to  
form on the surfaces of the contacts and/or it may interfere with the  
functions. Check out the atmosphere in which the units are to be  
stored and transported.  
The heat conduction by the equipment may accelerate the cooling of  
device itself, and the condensation may occur.  
Please conduct product evaluations in the worst condition of the actual  
usage. (Special attention should be paid when high temperature  
heating parts are close to the device. Also please consider the  
condensation may occur inside of the device.)  
Package  
In terms of the packing format used, make every effort to keep the  
effects of moisture, organic gases and sulfide gases to the absolute  
minimum.  
Icing  
Condensation or other moisture may freeze on relays when the  
temperature become lower than 0 °C.This icing causes the sticking of  
movable portion, the operation delay and the contact conduction failure  
etc. Panasonic Industry Co., Ltd. does not guarantee the failures  
caused by the icing.  
The heat conduction by the equipment may accelerate the cooling of  
relay itself and the icing may occur. Please conduct product  
evaluations in the worst condition of the actual usage.

Storage requirements  
3) The following cautionary label is affixed to the anti-humidity pack.  
Since the surface-mount terminal type is sensitive to humidity it is  
packaged with tightly sealed anti-humidity packaging. However, when  
storing, please be careful of the following.  
Silicon  
When a source of silicone substances (silicone rubber, silicone oil,  
silicone coating materials and silicone filling materials etc.) is used  
around the relay, the silicone gas (low molecular siloxane etc.) may be  
produced.  
1) Please use promptly once the anti-humidity pack is opened.(within  
72 hours, Max. 30 °C/70% RH). If left with the pack open, the relay  
will absorb moisture which will cause thermal stress when reflow  
mounting and thus cause the case to expand. As a result, the seal  
may break.  
This silicone gas may penetrate into the inside of the relay. When the  
relay is kept and used in this condition, silicone compound may adhere  
to the relay contacts which may cause the contact failure. Do not use  
any sources of silicone gas around the relay (Including plastic seal  
types).  
*For RE relays, after this bag is opened, the product must be used  
within 24 hours.  
2) If relays will not be used within 72 hours, please store relays in a  
humidity controlled desiccator or in an anti-humidity bag to which  
silica gel has been added.  
NOx Generation  
When relay is used in an atmosphere high in humidity to switch a load  
which easily produces an arc, the NOx created by the arc and the  
water absorbed from outside the relay combine to produce nitric acid.  
This corrodes the internal metal parts and adversely affects operation.  
Avoid use at an ambient humidity of 85%RH or higher (at 20 °C). If use  
at high humidity is unavoidable, please contact our sales  
representative.  
*If the relay is to be soldered after it has been exposed to excessive  
humidity atmosphere, cracks and leaks can occur. Be sure to mount  
the relay under the required mounting conditions  
*For RE relays, after this bag is opened, the product must be used  
within 24 hours.  
*RE Relays only  
Others  
Cleaning  
1) Although the environmentally sealed type relay (plastic sealed type,  
etc.) can be cleaned, avoid immersing the relay into cold liquid (such  
as cleaning solvent) immediately after soldering. Doing so may  
deteriorate the sealing performance.  
2) Surface-mount terminal type relay is sealed type and it can be  
cleaned by immersion. Use pure water or alcohol-based cleaning  
solvent.  
3) Cleaning with the boiling method is recommended (The temperature  
of cleaning liquid should be 40°C or lower).  
Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may  
cause breaks in the coil or slight sticking of the contacts due to the  
ultrasonic energy.
