1 General

MeshContact is a solderless technology new ly developed by Siemen s Matsushita Components. It

allows uniform concentric contacting o f MKP capacitor winds, avoiding the thermal stress caused

by soldering. The result is even better insertion loss, high insulati on resistance plus compact, small

casing.

Basically, feed- through components can be used to suppress interference in all electrical installa-

tions and equipment. The new ser ies is also ideal for telephone switching sy stems and base sta-

tions and, through broadband suppression effective into the GHz region, prevents interference pul-

ses from entering equipment from outs ide through the power supply network and vice versa.

There is now a building- block system available in this new technology for feed- through capacitors

and filters, allowing fast and attractively priced solutions to be implemented. Interim ratings can be

produced to order for special applic ations.

In feed- through capacitors the conductor carrying the load current is c onnected concentrically to

one electrode and passes through the center of the capacitor. The other electrode makes concentric

contact with the capacitor case.

Feed- through c apacitors are designed to be effective from low frequency to far above 300 MHz.

The low- loss winding with high- stability contact to t he leads at its face ends is enclosed in a metal

case with either a threaded stud at one end or an external thread.

Feed- through filters have π filter circuits consis ting of two equal shunt capacitors and on e ferro-

magnetic inductor connected in series. Due to t he concentric arrangement of t he components, high

attenuation values are obtained for frequencies up to and exceeding 1 GHz.

Safety note!

If feed- through elements with high capacitances are used, protective measures (e.g. protective

earthing) in accordance with equipment/system regulations (product standards) are required!

2 Mounting instructions

To fully utilize their RF characteristics, feed- through components must be fitted directly into the

shielding wall. The component case must make perfect and unbroken (RF- tight!) contact with the

shielding. This can be best achieved by screwing them into a threaded hole or bushing, so that good

electrical contact is made by the flanks of the thread.

As an alternative, feed- through elements can be scr ewed into feed- through holes in a shielding

wall and held by a retaining nut. Contact between the case and the shielding wall is produc ed by

the contact surface on the thread.

The connecting line must be attached by f ixi ng it between two countered nuts in order to avoid ex-

posing the component to torque loads (use two spanners).

NOTE

Due to the danger of exposing the feed throughs to mechanical loads caused by shock and

vibration, it is not permissible to use rigid copper bars as connecting elements.
