100 kHz Current Sense Transformer

West Coast Magnetics' 601 series current sense transformers are designed to accurately sense current at frequencies from 100 kHz to 600 kHz. They feature excellent linearity up to rated peak current. Compact size is optimized to minimize board space in two packaging configurations...through hole horizontal and through hole vertical mount.

notes

Notes:

For reliable performance at peak rated sense current, the sense windings must be connected in parallel to split the load.
For fully optimal performance, operate in recommended areas only. Within these ranges magnetizing current will be less than 1% of peak rated sense current and temperature rise will not exceed 40°C. Check with West Coast Magnetics for operation outside recommended areas.
