Abstract
This invention provides an electrical connector, particularly for devices having a low signal level, for example, thermocouple sensor circuits. The connector has: plural terminals for attachment of electrical leads; and connections for engagement electrically with mating conductors of an electrical component; and a body of ferrite material. There is an electrically conductive winding with multiple turns passing about the exterior of the ferrite body and having the winding ends electrically connected respectively to the terminals and to the connections to complete a circuit therebetween.
