The u200 filter Range has been specifically designed to overcome EMC problems inherently caused by switched mode power supplies, in applications especially where size constraints and low earth leakage are an issue.
This new range of micro size filters have high attenuation factors and high current capabilities without having a large profile. Switched mode power supplies electronically switch high voltages and currents to improve efficiency and reduce losses in power conversion. This switching generates high levels of Radio Frequency Interference (RFI) and high energy surges which can disturb or damage other electronics circuits.

The u200 series is a two stage design in 2, 3 or 4 line formats, with excellent suppression characteristics particularly at low frequency where switch mode power supplies tend not to perform and require effective attenuation. They also have very low earth leakage which give the added benefit of being able to be used in medical devices and applications.
The filter components are housed in compact chassis mounted, aluminium enclosures that allows side or base mounting, it is then encapsulated in a polyurethane potting compound to give excellent protection against shock and vibration. These combinations give a total range of over 50 filter applications.
