Features and Applications

The QPI-11LZ is a part of QPI Family EMI filter. It is specifically designed to attenuate conducted common-mode (CM) and differential-mode (DM) noise of the Vicor V•I Chip products to comply with the CISPR22 standard requirements for conducted noise measurements.

The filter is designed to operate up to 36 Vdc and supports 7 A loads up to 60°C without derating. Designed for the military and industrial bus range, the V•I Chip EMI Filter supports the PICMG® 3.0 specification for filtering system boards to the EN55022 Class B limits. Two of these filters can be connected in parallel to double current capability up to 14 A with a minor effect on attenuation at 1 MHz.
