Description

The QPI-11 EMI filter is specifically designed to

attenuate conducted common-mode (CM) and

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

specification for filtering system boards to the EN55022

Class B limits.
