Leaded Power Chokes – BCB Series
BCB Series
These power inductors are designed primarily for use as output chokes in switching power supplies.
They feature small size and low cost. The torrid core design offers the most inductance in the smallest part
size, while minimizing external magnetic fields.
These parts are suited for any application requiring a high DC current bias. The inductance values listed are
for parts when tested at low (10 gauss) levels of AC excitation. The parts are very well suited for use at higher
levels of AC excitation and will exhibit higher inductance.
