29/01/2008

Leading UK passive component manufacturer, Syfer, has announced the availability of a range of discoidal capacitors, offered in standard or custom configurations. Aimed primarily at manufacturers of EMI filters and filter networks, these robust and reliable devices will also meet the demands of equipment manufacturers in the communications, industrial, military/aerospace and sensors markets.

Discoidal capacitors offer high capacitance options, with values up to several microfarads. Rated voltage ranges from 50Vdc to 3kVdc, or higher on request. Operating temperature range is -55 to 125oC. The devices are offered with a choice of C0G/NP0 or X7R ceramic, or in MOV (metal oxide varistor) material for voltage protection applications.

In terms of mounting options, Syfer’s discoidal multilayer ceramic capacitors can be installed directly into filters, onto bulkheads, hybrid circuits or onto printed circuit boards. Their geometry gives them excellent RF performance characteristics as well as very high self resonant frequencies. Termination options include silver palladium, silver platinum or gold over nickel.
