1. General Information
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:
http://www.fujitsu.com/downloads/MICRO/fcai/relays/lead-free-letter.pdf
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
Recommended solder Sn-3.0Ag-0.5Cu.
RoHS Compliance and Lead Free Information
3. Moisture Sensitivity
Moisture Sensitivity Level standard is not applicable to electromechanical relays, unless otherwise indicated.
4. Tin Whiskers
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.
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: maximum 350-360˚C
Duration: maximum 3 sec.
