1. When ordering, please specify
packaging
codes:
PFL1610-102MEW
Packaging: W
= 7″ machine-ready reel. EIA-481 punched paper tape
(2000 parts per full reel).
U
= Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter W instead.
2. Inductance tested at 7.9 MHz, 0.1 Vrms using a Coilcraft SMD-F test
fixture with an Agilent/HP 4286 impedance analyzer and Coilcraft-
provided correlation pieces.
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 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.
