DC Filter Inductors

Osborne DC filter inductors (aka filter chokes) are commonly used in AC to DC conversion circuits to present an inductive voltage drop to the AC component of rectified current. This inductive voltage drop acts as a filter. Osborne designs filter inductors to  components to function effectively (without saturation) in the presence of the DC current. Osborne will work with you to mitigate the impact of ripple frequency in conversion circuits. Every Osborne DC filter choke is designed for high performance with special consideration given to your circuit´s power supply frequency and conversion configuration.
