SCHURTER FMBB EP series EMC filters

SCHURTER completes its portfolio of single-phase EMC filters with its FMBB EP series of ultracompact filters with high-performing attenuation. The double-stage filter family is claimed to be more powerful than typical filters, meeting the space constraints and performance requirements of today’s electronic devices.

The filters are said to feature high-quality components, including right-sized film capacitors, chokes with permeable cores and a steel housing that is completely closed and spot-welded at the bottom. The series provides high common-mode attenuation at low frequency, as well as common-mode and differential-mode attenuation over a wide frequency range, thus resulting in good broadband attenuation.

The filters are particularly suitable for use in applications confronted with stubborn electromagnetic interference, such as any equipment with fast semiconductor processing speeds at high switching frequencies, which are typically integrated into larger scale operations where exposure to other noise-generating devices exists. These operations include datacom, medical, industrial, and test and measurement, for example.

The filters are designed for rated currents ranging from 1 to 36 A at an ambient temperature of 40°C up to 250 V. Standard versions can be used over a temperature range from -40 to 100°C, with manufacturer-recommended deratings at higher temperatures. Variations in leakage currents are available for different applications (the standard version is 0.9 to 3.8 mA; for medical technology it is ≤5 or ≤80 µA).

The filter is easily installed to a chassis using the screw flange on both ends. Wires can be quick-connected or threaded to 6.3 x 0.8 terminals. The series is ENEC and cURus approved.
