VICOR QPI-21LZ

The QPI-21 active EMI filter attenuates conducted common-mode (CM) and differential-mode (DM) noise in the 150 kHz to 30 MHz frequency range specified by CISPR 22. Designed for 48 Vdc bus (36–76 Vdc) systems with 100 Vdc surge capability, the QPI-21 is rated at 14 A and supports multiple DC-DC converter loads without derating at ambient temperatures up to 65°C. Designed for telecom and ITE bus ranges, it supports the PICMG 3.0 specification and filters system boards to EN55022 Class B limits. Active filtering reduces component size compared to passive solutions, resulting in a smaller overall package footprint. The Picor QPI-21's compact form factor conserves valuable board space, and its reduced height promotes improved airflow. The QPI-21 is available as a lidded or open-frame SiP (System-in-Package) module in an LGA package. An evaluation board is available for rapid in-circuit testing of the QPI-21LZ within existing system designs.
