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. Model Installation Filter selection B84312C Upright Space-saving solution for installing a number of different filters. B84312C*B (2-line) B84312C*H (20-line) B84312F Flat Low profile and thus advantage especially for just one or a few filters.

The diagrams each show a circuit of a 2-line filter. In the series of 20-line filters there are 10 of them in each case. Circuit diagram 1 Circuit diagram 2 Circuit diagram 3 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. Filters for communication lines B84312 Analog systems and control lines
