Vicor | QPI-6LZ

The QPI-6LZ is a active EMI filter attenuates conducted commonmode (CM) and differential-mode (DM) noise over the CISPR22 frequency range of 150 kHz to 30 MHz. The product is designed for use on 48 Vdc bus (36 – 76 Vdc) systems, with 100 Vdc surge capability. The QPI-6’s 14 A rating supports multiple DC-DC converter loads up to an ambient temperature of 65°C without de-rating. Designed for the telecom and ITE bus range, the QPI-6 supports the PICMG® 3.0 specification for filtering system boards to the EN55022 Class B limits.

In comparison to passive solutions, the use of active filtering reduces the volume of the common-mode choke, providing a low profile, surface mount device. Smaller size saves valuable board real estate and the reduced height enhances airflow in blade applications. The QPI-6 is available as a lidded or an open-frame SiP (System-in-Package) with LGA mounting. Evaluation boards are available to allow for quick in-circuit testing of
the QPI-6LZ within an existing system design.
