1. When ordering, please specify
packaging
code:
XFL3012-472MEC
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).
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
DCR measured on a micro-ohmmeter.
SRF measured using Agilent/HP 4395A or equivalent.
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.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
