3. Moisture sensitivity

l

Moisture Sensitivity Level standard is not applicable to electromechanical realys.

4. tin Whisker

l

SnAgCu and SnCuNi solder is known as low risk of tin whisker. No considerable length whisker was found

by our in-house test.

We highly recommend that you confirm your actual solder conditions

1. General Information

l

Relays produced after the specific date code that is indicated on each data sheet are lead-free

now. Most of our signal and power relays are lead-free. Please refer to Lead-Free Status Info.

(http://www.fujitsu.com/us/downloads/MICRO/fcai/relays/lead-free-letter.pdf)

l

Lead free solder paste currently used in relays is Sn-3.0Ag-0.5Cu. From February 2005 forward

Sn-3.0CU-Ni will be used for the FTR-B3 and FTR-B4 series relays.

l

All signal and most power relays also comply with RoHS. Please refer to individual data

sheets. Relays that are RoHS compliant do not contain the 5 hazardous materials that

are restricted by RoHS directive (lead, mercury, chromium IV, PBB, PBDE).

l

It has been verified that using lead-free relays in leaded assembly process will not cause any

problems (compatible).

l

“LF” is marked on each outer and inner carton. (No marking on individual relays).

l

To avoid leaded relays (for lead-free sample, etc.) please consult with area sales office.

We will ship leaded relays as long as the leaded relay inventory exists.

Note: Cadmium was exempted from RoHS on October 21, 2005. (Amendment to Directive 2002/95/EC)
