7 A Active EMI Filter For 48 Vdc BusThe 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-4s 7 A rating supports multiple
DC-DC Converter loads up to a PCB temperature of
60C. At a 100C 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.
