RoHS Compliance and Lead Free Information

1. General Information

l All relays produced by Fujitsu Components are compliant with RoHS directive 2011/65/EU including

amendments.

l Cadmium as used in electrical contacts is exempted from the RoHS directives.

As per Annex III of directive 2011/65/EU.

l 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

l 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: maximum 350-360˚C

Duration: maximum 3 sec.

We highly recommend that you conrm 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.
