Dimensions of the terminals do not include thickness of pre-solder.Unit: mm( ) : Reference
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.

1. General Information All signal and power relays produced by Fujitsu Components are compliant with RoHS directive 2002/95EC including amendments. Cadmium as used in electrical contacts is exempted from the RoHS directives on October 21st, 2005. (Amendment to Directive 2002/95/EC) All of our signal and power relays are lead-free. Please refer to Lead-Free Status Info for older date codes at: http://www.fujitsu.com/us/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 Profile Recommended solder Sn-3.0Ag-0.5Cu.
RoHS Compliance and Lead Free Information
3. Moisture Sensitivity Moisture Sensitivity Level standard is not applicable to through hole mounted 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:Relay must be cooled by air immediately after soldering
dip within 5 sec. at 255°C±5°C solder bath
Solder by Soldering Iron:Soldering Iron: 30-60W Temperature: maximum 340-360˚CDuration: maximum 3 sec.
