August 25, 2020  Stephen Law

WüRTH ELEKTROINIK WE-CST EE4.4 series current sense transformers are made using an innovative manufacturing process, makes devices very small (4.7 x 4.65, 3.55mm), while also providing improved insulation. Devices insulation voltage of 750Vac, is 50% higher than that of market competitors. Product series type EE4.4 are suitable for a broad range of high frequency applications up to 1MHz with currents up to 7A. Devices display improved temperature behavior and are approved for the operating temperature range of -40 to +125°C. Products are available from in four different winding ratios from 1:20 to 1:150.
