1. When ordering, please specify termination and packaging codes:
MLC1±45-42±MLC
Termination: L= RoHS compliant tin-silver over copper.
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
Packaging: C= 7″ machine-ready reel. EIA-481 embossed plastic tape.
B= Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.
D= 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked.
