Current-compensated dual choke filter inductors are AEC-Q200 compliant

September 24, 2020  Stephen Law

BOURNS Model DR334A Line Filter Series of current-compensated dual choke filter inductors provide higher current capability than typical standard signal line common mode chokes, as well as high stray inductance and differential mode noise rejection. These capabilities make the devices suitable line filter solutions for consumer, industrial and other market power line applications, or in applications where power is transferred over signal lines. Products are available in a bifilar-wound configuration to reach higher common mode impedance, and a sector-wound configuration to reach higher differential mode impedance at high frequencies. Offered in a compact, low profile (height 3.6 mm) size and in a broad range of inductance ratings from 11 µH up to 4700 µH, devices allow designers to set the filter curve best suited to their application.
