Cary, IL, USA - Coilcraft announces its new CST7030 Series of surface mount current sense transformers which measure just 5.2 X 7.0 mm (with a max height of 3.0 mm) and sense up to 20 Amps of current at frequencies between 10 kHz and 1 MHz. Typical applications include load current measurement and control in switching power supplies and overload/short-circuit protection.

The devices are also qualified to AEC-Q200 Grade 1 (-40°C to +125°C) standards, making them ideal for conventional vehicle and xEV (EV, HEV, FCEV) applications such as current measurement in traction motors and battery management systems. They are also well suited for use in 48V vehicle systems.

The CST7030 Series is available with five turns ratios (primary-to-secondary) ranging from 1:20 to 1:150. It offers very low primary DC resistance (0.0015 Ohms) and 500 Vrms, one minute isolation (hipot) between windings. Coilcraft also offers a high-isolation (1,500 Vdc) version with its CU8965-AL Series.

CST7030 Series current sense transformers feature RoHS compliant tin-silver, over tin, over nickel, over phos bronze terminations and have a maximum reflow temperature of 260°C.

As with all Coilcraft parts, free evaluation samples are available online at www.coilcraft.com. Parts are available from stock and can be ordered online at buy.coilcraft.com or by calling Coilcraft sales.
