QPI Series EMI Filters

EMI filters that provide conducted CM and DM attenuation from Vicor

QPI Series EMI FiltersVicor's 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.

Features
  • Up to 60 dB CM attenuation at 250 kHz
  • Up to 80 dB DM attenuation at 250 kHz
  • Efficiency: >99% at full load
  • High density, low profile LGA package
  • Integrated Hot-Swap in select models
  • -40° to 100°C PCB temperature
  • TÜV approved
  • Saves up to 50% board space vs. standard filters
  • Compatible with most DC-DC converters
