Compact current sense transformers measure up to 20Amps

COILCRAFT CST7030 Series of surface mount current sense transformers measure 5.2 X 7mm (with a max height of 3mm) and sense up to 20 Amps of current at frequencies between 10kHz and 1MHz. Typical applications include load current measurement and control in switching power supplies and overload/short-circuit protection. Devices are also qualified to AEC-Q200 Grade 1 (-40C to +125C) standards, making them suitable for conventional vehicle and xEV (EV, HEV, FCEV) applications such as current measurement in traction motors and battery management systems. http://www.coilcraft.com
