Mn-Zn Ferrite Core and Oxygen-free Copper Achieve High Performance

CPD3119 series are designed with manganese zinc ferrite core with wide temperature, high frequency, and low loss. The EP shape magnetic core with excellent magnetic shielded ability to reduce electromagnetic interference.

The coil is wound with oxygen-free copper enameled flat wire, with excellent conductivity and high-speed signal transmission ability, which will not cause distortion at the output of the amplifier.
The compact design is suitable for various small volume and high-efficiency designs. It’s featuring an expanded inductance range, including 9 inductance values from 5μH to 33μH, saturation current ranges from 22.5 to 70Amps.
