X2Y Planar Arrays Syfer Technology Limited has been manufacturing and supplying Planar Capacitor Arrays since 1990, and is the world's leading supplier. X2Y planar arrays can also be offered, whereby pairs of lines in a connector can be filtered in an X2Y mode.  This is achieved by manufacturing the array with pairs of holes in an X2Y configuration, simultaneously providing capacitance line-to-ground and line-to-line.   For details of all our EMI filter products, see our latest EMI Filter Catalogue.

The multilayer Planar Array is an application specific component designed for use in multi-line EMI filter circuits, typically found in filtered connectors. Planar 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.
