Cautions
•
All values mentioned in this datasheet are provided under ideal conditions. Please perform the confirmation test
before actual use.
•
•
•
Reflow soldering is prohibited.
Do not use relays in the atmosphere with sulfide gas, chloride gas or nitric oxide. Contact resistance may increase.
Do not use silicon or silicon-containing product or materials near relays. It may cause contact failure.

RoHS Compliance and Lead Free Information
1. General Information
l
l
l
l
All relays produced by Fujitsu Components are compliant with RoHS directive 2011/65/EU including
amendments.
Cadmium as used in electrical contacts is exempted from the RoHS directives.
As per Annex III of directive 2011/65/EU.
All relays are lead-free. Please refer to Lead-Free Status Info for older date codes at:
Lead free solder plating on relay terminals is Sn-3.0Ag-0.5Cu, unless otherwise specified.
This material has been verified to be compatible with PbSn assembly process.
2. Recommended Lead Free Solder Condition
l
Recommended solder Sn-3.0Ag-0.5Cu.
Flow Solder Condition:
Pre-heating:
maximum 120˚C
within 90 sec.
Soldering:
dip within 5 sec. at
255˚C
±
5˚C solder bath
Relay must be cooled by air immediately
after soldering
Solder by Soldering Iron:
Soldering Iron
30-60W
Temperature:
Duration:
maximum 350-360˚C
maximum 3 sec.
We highly recommend that you confirm your actual solder conditions
3. Moisture Sensitivity
l
Moisture Sensitivity Level standard is not applicable to electromechanical relays, unless otherwise indicated.
4. Tin Whiskers
l
Dipped SnAgCu solder is known as presenting a low risk to tin whisker development. No considerable length
whisker was found by our in house test.
