Broadband Conical Inductors
Coilcraft’s conical inductors are designed specifically for
broadband and high frequency applications. This single
component operates as a series of narrow-band inductors throughout an operating frequency range of 10 MHz
to 40 GHz.
These conical inductors are ideal for use in ultra-wideband bias T’s. In this application, the conical inductor
provides the path for the DC bias injection or extraction
while isolating the power source from the active device.
The BCL versions are supplied with “flying leads” that
allow adjustment of the mounting angle. Each surface
mount BCS inductor has a self positioning mounting
bracket.
To request evaluation samples, contact Coilcraft.

1. When ordering, please specify packaging code:
Packaging:
BCS-802JLC
C = 7″ machine-ready reel. EIA-481 embossed plastic tape
(BCS-122JL: 500 parts per full reel;
BCS-531JL and BCS-802JL: 300 parts per full reel;
BCS-652JL: 200 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.
2. Inductance measured at 10 MHz, 0.1 Vrms, 0 Adc using an Agilent/
HP 16092A fixture in an Agilent/HP 4291A impedance analyzer.
3. Current that causes a 40°C temperature rise from 25°C ambient.
4. Ambient temperature range: –40°C to +85°C
5. Storage temperature range: Component: –40°C to +85°C
Packaging: –40°C to +80°C
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
