Planar Arrays

Planar Arrays

API Technologies designs and manufactures a wide range of Planar Array Ceramic Capacitors for EMI filtering. Built using over 25 years expertise in multi-layer ceramic capacitor manufacturing, planar capacitors offer many advantages over stand-alone chip, discoidal or tubular capacitors: low profile, compact, quick assembly time. Various custom and industry standard geometries are available. Designs can incorporate multiple capacitance values, feed-thru holes and ground holes. With a combination of versatility and function, planar ceramic capacitors are quickly becoming the new standard in filtered connectors used in EMI suppression applications.
