The u202 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 is an issue.
These new ranges 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 u202 series is a two stage design in a 2 line format, with excellent suppression characteristics particularly
at 10K - 200KHz where power supplies tend not to perform and require effective attenuation, the filter will also effectively reduce harmonic distortion. They also have very low earth leakage which gives the added benefit of being able to be used in medical devices and applications.
The filter components are housed in compact chassis mounted, aluminum 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 20 filter applications.
