1. When ordering, please specify packaging code:
EPL3012-223MLC
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 4395A network analyzer or equivalent.
5. DC current at which the inductance drops the specified amount from its
value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
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).
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Specifications subject to change without notice.
