RoHS Compliance and Lead Free Information

1. General Information

l All signal and power relays produced by Fujitsu Components are compliant with RoHS directive 2002/95EC

including amendments.

l Cadmium as used in electrical contacts is exempted from the RoHS directives on October 21st, 2005.

(Amendment to Directive 2002/95/EC)

l 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

l Lead free solder plating on relay terminals is Sn-3.0Ag-0.5Cu, unless otherwise specied.

This material has been veried to be compatible with PbSn assembly process.

2. Recommended Lead Free Solder Prole

l Recommended solder Sn-3.0Ag-0.5Cu.

Flow Solder condition:

Pre-heating: maximum 120˚C
Soldering: dip within 5 sec. at
260˚C solder bath

Solder by Soldering Iron:

Soldering Iron
Temperature: maximum 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.
