12 Amp Active EMI Filter for 48 V DC Bus
Description
The QPI-1 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-1âs 12 A rating supports multiple
DC-DC converter loads up to a PCB temperature of
60°C. At a 100°C PCB temperature the QPI-1 supports
10 A loads. Designed for the telecom and ITE bus range,
the QPI-1 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-1 is available in a 1.0" x 1.0" x 0.2" SiP (System
in Package) with LGA mounting. QPI-1-EVAL1 kits are
available for testing the QPI-1. The evaluation board
has a mounted QPI-1 with screw terminals for quick
in-circuit testing.

board and the QPI-AN1 Application Note.
