7 A V·I Chip EMI Filter
QPI-11
QUIETPOWER^®
Description
The QPI-11 EMI filter is specifically designed to
attenuate conducted common-mode (CM) and
differential-mode (DM) noise of the VICOR V•I Chip
products to comply with the CISPR22 standard
requirements for conducted noise measurements. The
filter is designed to operate up to 36 Vdc and supports
7 A loads up to 60°C without derating.
Designed for the military and industrial bus range, the
V•I Chip EMI Filter supports the PICMG® 3.0
specification for filtering system boards to the EN55022
Class B limits.
