1. General Information
l Relaysproducedafterthespecic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.
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veried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).
