General
MeshContact is a solderless technology newly developed by Siemens Matsushita Components. It
allows uniform concentric contacting of MKP capacitor winds, avoiding the thermal stress caused
by soldering. The result is even better insertion loss, high insulation resistance plus compact, small
casing.
Basically, feed-through components can be used to suppress interference in all electrical installa-
tions and equipment. The new series is also ideal for telephone switching systems and base sta-
tions and, through broadband suppression effective into the GHz region, prevents interference puls-
es from entering equipment from outside 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 applications.

In feed-through capacitors the conductor carrying the load current is connected concentrically to
one electrode and passes through the center of the capacitor. The other electrode makes concentric
contact with the capacitor case.
Feed-through capacitors are designed to be effective from low frequency to far above 300 MHz. The
low-loss winding with high-stability contact to the 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 consisting of two equal shunt capacitors and one ferro-
magnetic inductor connected in series. Due to the concentric arrangement of the 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!

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 screwed into feed-through holes in a shielding wall
and held by a retaining nut. Contact between the case and the shielding wall is produced by the
contact surface on the thread.
The connecting line must be attached by fixing 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.
