Knowles Precision Devices Multi-Layer Planar Capacitor Array

The multilayer planar array is an application specific multi capacitor array designed for use in multi-way EMI filter circuits. Derived from discoidal capacitor theory, it provides capacitance between the outside perimeter and the internal through holes. The most common use of planar arrays is as the capacitor element in filter connectors, although they are also suitable in many other applications. Our core wet manufacturing process and ceramic handling expertise allows components to be produced with mechanical precision and electrical accuracy, enabling a filter assembly to withstand the most rigorous of electrical specifications. This has resulted in our position as the manufacturer of choice for the filter connector industry. To date, we have delivered in excess of 3,000 different designs of planar array. The quality and reliability of our planar arrays has been uniquely recognized by the approval of NASA for their use in the International Space Station.
