Picor QuietPower EMI Input Filter Modules

The Picor QuietPower QPI family of active EMI filters provides conducted common-mode (CM) and differential-mode (DM) attenation 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.

The MQPI-18 attenuates conducted common-mode (CM) and differential mode (DM) noise for 28 V input MIL PRMs to comply with MIL-STD-461F EMI requirements for conducted noise measurements. The filter operates within the full input operating range of a 28 V MIL PRM and supports 7 A loads up to 85°C (TA) without de-rating.
