| Filters for Communication Lines ISDN Systems Series/Type: B84312 Date: January 2004 (c) EPCOS AG 2004. Reproduction, publication and dissemination of this data sheet, enclosures hereto and the information contained therein without EPCOS' prior express consent is prohibited. Purchase orders are subject to the General Conditions for the Supply of Products and Services of the Electrical and Electronics Industry recommended by the ZVEI (German Electrical and Electronic Manufacturers' Association), unless otherwise agreed. Filters for communication lines ISDN systems B84312 For ISDN-Interfaces S0, S2, UP0 and U2 plus Siemens Hicom installations 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 Installation Single filters are attached straight to the shielding wall. Larger numbers can be housed in filter cabinets or boxes. Various models and the matching flexible connector fittings are available.
