Applications

Product Description

The QPI family of active EMI filters provides conducted

common-mode (CM) and differential-mode (DM) attenuation

from 150 kHz to 30 MHz (CISPR22 range). The proprietary

active filtering circuit provides superior attenuation at

low frequencies intended to support EN Class B limits,

including PICMG^®3.0 for ATCA boards.

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.
