High Reliability SMD Common Mode Choke Filter with Ferrite Core for EMI Noise Suppression and Low DC Resistance

The DLF Series is a compact SMD Common Mode Choke Filter designed to suppress common mode noise in power and signal lines of electronic equipment. By providing stable impedance characteristics across the specified frequency range, this series effectively reduces electromagnetic interference while maintaining signal integrity.

As an EMI Suppression CMC Inductor, the DLF Series utilizes a ferrite core structure optimized for surface-mount assembly. The controlled inductance and low DC resistance design help minimize insertion loss and power dissipation, making it suitable for high-density PCB layouts.

All electrical characteristics, package dimensions, and rated current values strictly follow the specifications defined in the provided product documentation. Multiple size options are available within the series to support different circuit requirements and EMI suppression levels.
