Improved electrical properties Feedthrough filters and capacitors EPCOS has made further improvements to its range of feedthrough filters and capacitors for telecom applications. The new, solder-free Meshcontact technology developed at the Heidenheim plant in conjunction with self-healing MKP capacitor windings (metalized polypropylene films with dry impregnation) has led to significant improvements in insertion attenuation and insulation resistance. The new feedthrough components in compact cases are significantly smaller than their predecessors. In addition, the thermal stress of soldering is avoided, thus preventing any damage to windings. Feedthrough filters and capacitors are used in telecommunications applications, especially in central offices and base stations. They ensure broadband interference suppression right up into the gigahertz range, thus preventing noise pulses from entering or escaping from equipment via the supply network. But feedthrough components can be used for interference suppression in virtually any electrical installation or application. EPCOS will phase in solder-free contacting for its entire range of feedthrough components. A modular system with component diameters of 30 and 55 mm is being introduced as standard to cover current ranges of 25, 63, 75, 100, 200, 300, 400 and 500 A with capacitances from 0.1 to 4.7 µF. Components can be supplied with intermediate capacitances for special applications on request. Thanks to the modular design of these components, samples are available at short notice.
