Würth Elektronik WE-CST EE4.4 current sense transformers
Würth Elektronik expands its WE-CST current sense transformers with the WE-CST EE4.4 series. An innovative manufacturing process means the current sense transformers are ultrasmall (4.7 x 4.65 x 3.55 mm) with an insulation voltage of 750 VAC — said to be 50% higher than that of market competitors. The series is suitable for a broad range of high-frequency applications up to 1 MHz with currents up to 7 A.
Applications for the minute SMT-mountable current sense transformers include AC current measurement, switched mode power supplies, overload detection, load shedding and disconnect detection, metering, load measurement and high-frequency current sensing. The product displays good temperature behaviour and is approved for the operating temperature range of -40 to +125°C. It is available in four different winding ratios from 1:20 to 1:15; five further variants are set to be added.
