12.2. Soldering Conditions
Products can be applied to reflow soldering.
(1) Flux , Solder
Flux
Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.
Solder
Use Sn-3.0Ag-0.5Cu solder
Standard thickness of solder paste : 100 µm to 200 µm
Use of Sn-Zn based solder will deteriorate performance of products.
In case of using Sn-Zn based solder, please contact Murata in advance.
(2) Soldering conditions
· Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is
limited to 150°C max. Also cooling into solvent after soldering should be in such a way that the temperature
difference is limited to 100 °C max.
Insufficient pre-heating may cause cracks on the ferrite, resulting in the deterioration of product quality.
· Standard soldering profile and the limit soldering profile is as follows.
The excessive limit soldering conditions may cause leaching of the electrode and / or resulting
in the deterioration of product quality.

Products should be used within 5 V(DC) between elements.
When the products are used the excessive voltage over 5 V(DC) , it may cause breaking of inner electrade
and / or decreasing o insulation resistance between elements.
12.7. Mounting density
Add special attention to radiating heat of products when mounting the inductor near the products with heating.
The excessive heat by other products may cause deterioration at joint of this product with substrate.
12.8. Cleaning Conditions
Products shall be cleaned on the following conditions.

12.9.Handling of a substrate
After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the
substrate when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to
the substrate.
Excessive mechanical stress may cause cracking in the product.

12.10. Operating Environment
Do not use this product under the following environmental conditions, on deterioration of the Insulation Resistance of
the Ferrite material and/or corrosion of Inner Electrode may result from the use.
(1) in the corrodible atmosphere (acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and etc.)
(2) in the atmosphere where liquid such as organic solvent, may splash on the products.
(3) in the atmosphere where the temperature / humidity changes rapidly and it is easy to dew.
12.11. Resin coating
The impedance value may change and/or it may affect on the product’s performance due to high cure-stress of resin
to be used for coating / molding products. So please pay your careful attention when you select resin. In prior to use,
please make the reliability evaluation with the product mounted in your application set.
12.12. Storage Conditions
(1) Storage period
Use the products within 6 months after delivered.
Solderability should be checked if this period is exceeded.
(2) Storage coditions
· Products should be stored in the warehouse on the following conditions.
T
e
mperature : – 10 °C to 40 °C
Humidity
: 15 % to 85 % relative humidity
No rapid change on temperature and humidity
· Don’t keep products in corrosive gases such as sulfur, chlorine gas or acid, or it may cause oxidization
of electrode, resulting in poor solderability.
· Products should be stored on the palette for the prevention of the influence from humidity, dust and so on.
· Products should be stored in the warehouse without heat shock, vibration, direct sunlight and so on.
