High-Performance EMI Filters and Feedthrough Capacitors for EMC Noise Suppression with Ceramic Dielectric Materials

Product Details

Our high-reliability EMI Filters and Feedthrough Capacitors are engineered to provide superior electromagnetic interference suppression for demanding applications across industrial electronics, power systems, communication equipment, medical devices, and military-grade systems.

Designed with high-quality ceramic dielectric materials (NPO, X7R, Y5V, Y5U, etc.), these filters deliver outstanding stability, low insertion loss, and consistent performance across a wide frequency spectrum—from kHz to GHz.

The product range covers Solder-in Filters, Metal-Shell Feedthrough Filters, Resin-Sealed Bolt-in Filters, Special Custom Filters, and Tubular Ceramic Capacitors, offering flexible installation options for both PCB and panel-mount systems.

With multiple capacitance values, high rated voltages (up to 500 VDC), and current ratings from 5A to 35A, this series meets stringent global EMC requirements and ensures reliable suppression of conducted and radiated noise.

These components are ideal for customers seeking compact, rugged, and cost-effective EMI suppression solutions with stable electrical properties and long operational life.
