SMT Broadband Conical 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.
• 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 T’s, where the conical in-
ductor provides the path for the DC bias injection or extraction
while isolating the power source from the active device.
• For a “flying lead” version that allows adjustment of the
mounting angle consider the BCL series

1. When ordering, please specify
termination
and
packaging
codes:
BCR-802JLC
Termination: L =
Tin-silver-copper over silver-platinum-glass frit
Special order, added cost:
S
= Tin-lead over silver-platinum-glass frit
C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape
BCR-122JL: 500 parts per full reel;
BCR-531JL and BCR-802JL: 300 parts per full reel;
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. 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.
