7 A Active EMI Filter For 48 Vdc Bus

The QPI-4 active EMI Filter attenuates conducted common-mode (CM) and differential-mode (DM) noise over the CISPR22 frequency range of 150 kHz to 30 MHz. The product is designed for use on a 48 Vdc bus (36 – 76 Vdc). The QPI-4 s 7 A rating supports multiple DC-DC Converter loads up to a PCB temperature of 60°C. At a 100°C PCB temperature the QPI-4 supports 6 A loads. Designed for the telecom and ITE bus range, the QPI-4 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-4 is available in a 25 x 25 x 4.5 mm SiP (System-in-Package) with LGA mounting. QPI-4-EVAL1 kits are available for testing the QPI-4. The evaluation board has a mounted QPI-4 with screw terminals for quick in-circuit testing.
