High Voltage MLC Capacitors

Our High Voltage Capacitors feature a special internal electrode design which reduces voltage concentrations by distributing voltage gradients throughout the entire capacitor. These capacitors are designed and manufactured to the general requirement of EIA198 and are subjected to a 100% electrical testing making them well suited for a wide variety of telecommunication, commercial, and industrial applications.

EMI Filters using X2Y technology

Superior EMI filtering performance virtually eliminates parasitics switching loads such as electric motors, transformers, heaters, lamps, ballast, power supplies, etc., causing EMI issues? We have a solution for that.
