This document introduces the features and characteristics of the B84263 power filter produced by EPCOS AG. The filter uses a multi-stage design and can achieve 100 dB of attenuation in the frequency range from 14 kHz to 40 GHz. The filter has a small volume and low voltage drop, and it produces almost no leakage current in normal operation.
This document is a technical datasheet for the EPCOS B84263 series of filters designed for power lines with low leakage current. The filters are available in 2-line and 4-line configurations, supporting currents from 16 to 100 A, and provide an attenuation of 100 dB starting at 14 kHz up to 40 GHz.
The datasheet details the features, design, protective measures, and installation instructions for these RF-tight steel case filters. It includes general technical data such as rated voltage (250 V or 440 V), frequency (50/60 Hz), and maximum permissible harmonic distortion. Specific characteristics tables list dimensions, weights, power dissipation, and leakage current values based on the mechanical version (cable glands vs. direct connection) and current rating.
