Planar Capacitor Arrays

Syfer Technology Limited has been manufacturing and supplying Planar Capacitor Arrays since 1990, and is the world's leading supplier. The multilayer ceramic Planar Capacitor Array is an application specific component designed for use in multi-line EMI filter circuits, typically found in filtered connectors. Planar Capacitor Array technology affords the user weight and volumetric efficiency as well as performance and reliability advantages compared to other capacitor technologies. Syfer's leading position has been achieved through utilisation of the advantages inherent in our "Wet-Stack" process. A stress-free component is produced with mechanical precision, enabling a filter assembly to withstand the most rigorous of electrical specifications.

The Planar Capacitor Array is a unitary block of ceramic containing capacitors or a combination of capacitors, feedthrus and ground lines. Our current capability extends from a simple 2 hole unit to a complex 155-way device. Individual line connection is made to each capacitor through a terminated hole, whilst the ground connection is made at the device perimeter. Very low impedances are encountered as signals are presented with multi-directional paths to ground.

Working with customers in the EMC field has enabled Syfer to develop a comprehensive range of planforms.
These include the following:-

● Circular (MIL-C-38999 and similar)
● ARINC 404 and 600
● "D" SUB (Rectangular and Trapezoidal)
● High Density "D" SUB
● Micro-D (MIL - C - 83513)

Special custom shapes are also available, please contact us with your custom requirements. Component thicknesses are produced from a minimum of 1.40mm (0.055") to 3.18mm (0.125").
