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

Top-quality components, including right-sized film capacitors and chokes with highly permeable cores, together with a steel housing, which is completely closed and spot-welded at the bottom, are critical design aspects of the FMBB EP’s. The filter family provides exceptional common-mode attenuation at low frequency, as well as common mode and differential mode attenuation over a wide frequency range, thus resulting in excellent broad band attenuation.

The FMBB EP is particularly suited for use in applications confronted with the most stubborn electro-magnetic interferences, such as any equipment with extremely fast semiconductor processing speeds at high switching frequencies, which are typically integrated into larger scale operations, where exposure to other noise generating devices exist. These operations for example include datacom, medical, test and measurement, and industrial.

The FMBB EP filters are designed for rated currents ranging from 1 A 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 °C to 100 °C, with manufacturer recommended deratings at higher temperatures. Variations in leakage currents are available for different applications: the standard version with 0.9 mA to 3.8 mA, for medical technology ≤ 5 µA or ≤ 80 µA. The FMBB EP 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.
