BCR Series

Surface Mount Broadband Conical Inductors

These conical inductors are designed for applications up to 40 GHz. For applications up to 6 GHz, consider one of the lower cost 4310LC wideband bias chokes.

Coilcraft BCR Series conical inductors were designed specifically for broadband and high frequency applications, operating as a series of narrow-band inductors across a frequency range of 10 MHz to 40 GHz. They are ideal for use in ultra-wideband bias Tees. Their full-length cap protects the coil and provides a large surface for pick and place.

Flat bandwidth with high impedance to 40 GHz; ideal for use as bias Tee inductors
Full-length cap protects the coil and provides a large surface for pick and place
The self positioning mounting bracket has four soldered pads for excellent board adhesion.
Operates as a series of narrow band inductors
See our BCL for a "flying leads" version that allows adjustment of the mounting angle

Notes

When ordering, please specify termination and packaging codes: e.g. BCR-802JLC
Inductance measured at 10 MHz, 0.1 Vrms, 0 Adc using an Agilent/HP 16193A fixture in an Agilent/HP 4287A LCR meter or equivalent.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Irms: Current that causes a 40°C rise from 25°C ambient. Details

Termination:

L = Tin-silver-copper over silver-platinum-glass frit.
S = Tin-lead over silver-platinum-glass frit. (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part 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.
