SCS High-Frequency Current-Sensing Transformers

Signal Transformer / Bel SCS High-Frequency Current-Sensing Transformers are SMD devices designed to operate from 50kHz to 1MHz frequencies. These transformers are able to sense current from 7A to 15A and are available in compact size. The SCS 4/8 transformers feature low DC resistance, different tune ratios, a 0.033mH to 22mH inductance range, and a -40°C to 125°C temperature range. These transformers are used in feedback control, switching power supplies, portable communication equipment, motor control, DC-DC converters, LCD televisions, and overload sensing devices.
