1. When ordering, please specify packaging code:
PFL4517-103MEC
Packaging:C=7″ machine-ready reel. EIA-481 embossed plastic tape (1000 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 (5000 parts per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms, 0Adc.
3. DCR measured using a micro-ohmmeter.
4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
5. DC current that causes the specified inductance drop 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.
