Dual choke filter inductors feature higher current capability

Bourns’ new dual choke filter inductors feature higher current capability than typical standard signal line common-mode chokes and a wide inductance range.

Bourns, Inc. has released its new Model DR334A line filter series, targeting consumer, industrial and other power line applications and applications where power is transferred over signal lines. These current-compensated dual choke filter inductors feature higher current capability than typical standard signal line common-mode chokes, along with high stray inductance and differential mode noise rejection, said Bourns.

Bourns DR334A dual choke filter inductorsThe Model DR334A series is 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. Offering a wide inductance range from 11 µH up to 4700 µH, the line filters allow designers to set the filter curve best suited to their application.

The low-profile choke filter inductors series is AEC-Q200 compliant and operates over an extended temperature range of -40°C to 135°C. The rated voltage is up to 80 VDC. The line filter series offers a more efficient and robust mechanical design thanks to the closed and ferrite toroid core construction.

The Model DR334A series is available now. The devices are RoHS compliant and halogen free.

Bourns also recently introduced a new series of AEC-Q200 compliant CANbus common-mode chip inductors, targeting a wide range of high temperature electronics.
