Current Sense Transformer

Current transformers accurately sense and measure current flow in power supply circuits in a non-invasive way. Ideally, they shunt a very small sample of the current to measure while dissipating minimal energy. The sensed current information is typically used to prevent overcurrent conditions and to monitor and control circuits in power supplies and other powered applications. 

FKS COILS  offers a wide selection of surface mount current sense components for various types of switching mode power supply topologies.
