Discoidal Ceramic Capacitors

Ceramic Capacitors

Discoidal feedthrough ceramic capacitors are the building blocks of the EMI filter industry. These discoidal capacitors provide great versatility in meeting varied voltage, capacitance and dimensional requirements. The non-polar, multi-layer capacitors are small, reliable and high in dielectric strength.  

The low profile designs are also available in various OD, ID, and thickness.  We are currenty offering mini discoidals as small as to 0.059."
