1. Please specify termination and packaging codes:
ME3215-104KLC
Termination: L = RoHS tin-silver-copper over tin over nickel over silver.
Special order:
S = non-RoHS tin-lead (63/37).
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 per full reel). Quantities less than full reelavailable: in tape (not machine ready) or with leader
and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastictape. Factory order only, not stocked (7000 parts perfull reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft
SMD­‑A fixture in Agilent/HP 4284A impedance analyzer.
3. DCR measured on a micro-ohmmeter and Coilcraft CCF858 testfixture.

4. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft
SMD­‑D test fixture.
5. DC current at which the inductance drops the specified amount fromits value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
