SMTPowerInductors–EPL2010Series
Document 584-1
Revised 04/21/08
1. When ordering, please specify termination and packaging codes:
EPL2010-103M
LC
Termination: L = RoHS compliant tin-silver over gold over nickel over
silver.
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 (2000 parts per full reel).
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 (7500 parts per
full reel).
