QPI-21

Active EMI Input Module for 48 Vdc Bus Quiet-Power® QPI-21 S C NRTL US Product Description The QPI-21 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 in 48 Vdc bus (36 – 76 Vdc) systems, with 100 Vdc surge capability. The QPI-21’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-21 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 component size and therefore reduces the overall package size. The Picor QPI-21 smaller size saves valuable board real estate and the reduced height enhances airflow. The QPI-21 is available as a lidded or an open-frame SiP (System-in-Package) module with LGA mounting. Evaluation boards are avai...
