EMI power filters are designed to improve the electromagnetic compatibility (EMC) of equipment by suppressing conducted noise on power lines, ensuring stable operation in complex electromagnetic environments. They effectively attenuate both common-mode and differential-mode interference through low-pass networks composed of inductors, capacitors, and other protective components.

Filters are available in DC, single-phase AC, and three-phase AC types, and are offered in various structures such as plug-in, leaded, bolt-mounted, and chip types. The company provides multiple quality assurance levels—including Industrial (I), General Military (P), Military Tactical (J), Strategic (B), and Enterprise Military Standard (OJB)—to meet application needs ranging from consumer electronics to aerospace.

Key technical parameters include rated voltage and current, operating frequency, dielectric withstand voltage, leakage current, insulation resistance, and insertion loss, which together define the filter’s safety, reliability, and performance.
