Filters for communication lines
Analog systems and control lines
B84312
Passband up to 300 kHz
Stopband attenuation up to 40 GHz
Features
Use of coaxial feed-through capacitors on input and output
Single or current-balanced chokes depending on requirement
Insertion loss to CISPR 17
Also available with integrated EMP protection
Installation
Single filters are attached directly to the shielding wall. Larger numbers can be housed in filter
cabinets or boxes. Various models and the matching flexible connector fittings are available.
Mechanical design
The electrical components are incorporated in an RF-tight case of tin-plated sheet steel. Filters
are available for 2 or 20 lines and for upright or flat installation on shielding wall.

Note on circuit diagrams 2 and 3:
These filters are mounted with current-compensated chokes. Make sure that the forward and re-
turn line are routed paired through one filter.
