Active EMI Filter (QPI)
PRODUCT DESCRIPTION
The QPI family of active EMI filters provides conducted common-mode (CM) and differential-mode (DM) attenuation from 150kHz to 30MHz (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.
Models QPI-3 through QPI-8 are designed to work with most switch-mode power supplies. The QPI-9 through QPI-12 products are designed specifically for
use with Vicor’s V•I Chip power conversion products.
Full-size QPI models are 25x25x4.5mm SiP (System in Package), with LGA mounting. QPI-11 and QPI-12 are half size 12.5x25x4.5mm SiPs.
