Abstract
Generally, a DC power filter and its associated components are presented herein. The DC power filter may operate in a telecommunications chassis between one or more electrical sources and one or more loads. A common mode noise shunt may be included to shunt noise from more than one of the electrical sources or loads together. Additionally, the DC power filter may include protection circuitry that is coupled to more than one of the electrical sources. The protection circuitry may include a combination of diodes and other transient voltage suppression devices.
