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.
  • Flat bandwidth with high impedance to 40 GHz; ideal for use as bias Tee inductors
  • Full-length cap fully 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
  • RoHS Compliant. 260°C compatible. Tin-silver-copper over silver-platinum-glass frit terminations.
  • See our BCL for a "flying leads" version that allows adjustment of the mounting angle.

1 When ordering, please specify termination and packaging coded: e.g. BCR-802JLC
  Termination: L = Tin-silver-copper over silver-platinum-glass frit
Special order, added cost:
= Tin-lead over silver-platinum-glass frit
  Packaging: C = 7" machine-ready reel.
EIA-481 embossed plastic tape:
BCR-122JL: 500 parts per full reel
BCR-162JL, BCR-221JL, BCR-232JL, BCR-531JL, BCR-801JL: 300 parts per full reel
BCR-272JL, BCR-632JL, BCR-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 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Irms: Current that causes a 40°C rise from 25°C ambient. Details
5 Ambient temperature range: −40°C to +85°C
6 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
7 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
8 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
