numbering system, Coilcraft is eliminating the need
for multiple packaging codes.When ordering, simply
change the last letter of your part number from B to C.

2. Inductance measured at 100 kHz, 0.1Vrms, using aCoilcraft SMD-A fixture
in an Agilent/HP 4263B LCR meter.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 1 MHz on an Agilent/HP 4291 with an Agilent/HP 16193 test
fixture.
5. DCR measured on micro-ohmmeter and a Coilcraft CCF840 test fixture.
6. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft
SMD-D test fixture.
7. DC current at 25°C that causes an inductance drop of 10% (typ) from its
value without current.Click for temperature derating information.
8. Current that causes the a 40°C temperature rise from 25°C ambient.This
information is for reference only and does not represent absolute maximum
ratings.Click for temperature derating information.
