SMT Broadband Conical Inductors
• Designed specifically for broadband and high frequency
applications.
• Operates as a series of narrow-band inductors throughout
an operating frequency range of 10 MHz to 40 GHz.
• Ideal for use in ultra-wideband bias Tees, where the conical
inductor provides the path for the DC bias injection or extraction while isolating the power source from the active device.
• Each surface mount inductor has a self positioning mounting bracket.
• For a “flying lead” version that allows adjustment of the
mounting angle consider the BCL series
For new designs, consider the BCR as an alternative.
The BCR is electrically identical, and has a much
more rugged package. It features a full length
cover that completely protects the coil and four
mounting pads for excellent board adhesion. We
will continue to manufacture and support the BCS
series indefinitely.

1. When ordering, please specify packaging code:
BCS-802JLC
Packaging: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
16193A fixture in an Agilent/HP 4287A LCR meter or equivalents.
3. Current that causes a 40°C temperature rise from 25°C ambient.
4. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
