Revised 9/14/01
These shielded chip inductors have been specially de-
signed for high performance in transmit and receive
filters.
They feature high inductance, an exceptionally wide
frequency range, and magnetic shielding to reduce
crosstalk.
Only 3.81 mm high, these inductors have a ferrite cover
that provides magnetic shielding and the best possible
surface for pick and place handling.

1. Inductance measured at 100 kHz, 0.1 Vrms, using Coilcraft SMD-A fixture in
Agilent/HP 4263B impedance analyzer with Coilcraft-provided correlation
pieces. For recommended test procedures, contact Coilcraft.
2. Tolerances in bold are stocked for immediate shipment.
3. Q measured on Agilent/HP4291 with Agilent/HP16193 test fixture.
4. DCR measured on micro-ohmmeter and Coilcraft CCF 840 test fixture.
5. SRF measured using Agilent/HP8753D network analyzer and Coilcraft
SMD-D test fixture.
