Feedthrough components

General

Feedthrough components from EPCOS are used for EMI suppression of all electrical installations

and equipment. This new type series is also outstandingly well suited for telephone exchanges and

base stations. Thanks to broadband EMI suppression up to the GHz range, it prevents external in

terference pulses being transmitted to the inside of the equipment via the supply network and vice

versa.

The essential features of this new type series are its modular design and the solder-free contacting

technology developed by EPCOS with the aid of mesh contact.

Mesh contact technology permits uniform concentric contacting of the MKP capacitor winding and

avoids the thermal stress associated with soldering. The result is an even higher insertion loss, a

high insulation resistance and a particularly compact case.

The modular system used in this new technology for feedthrough capacitors and filters allows the

cost-effective implementation of a wide range of standard types. Other capacitance values can also

be supplied for special applications upon request.

Feedthrough components fitted

into a shielding wall.

In feedthrough capacitors, the conductor carrying the operating current is connected concentrically

to one electrode and is run centrally through the capacitor. The other electrode is contacted con

centrically to the capacitor case.

Feedthrough capacitors are dimensioned so that they perform well from low frequencies to far above

300 MHz. The capacitor element with low inductance contacted securely on the face side is

incorporated in a metal case provided with a screw thread.

The feedthrough filters are constructed in a

π-circuit.

They consist of two identical capacitative

transverse elements and an inductive longitudinal element. The concentric layout of the compon

ents allows high insertion loss values to be attained in a frequency range to above 1 GHz.

Safety note

Feedthrough components with high capacitances require the implementation of safety measures in

line with the applicable specifications! (See also Chapter “Mounting instructions”.)
