WE-FLEX Flexible Transformers

Würth Elektronik WE-FLEX Flexible Transformers for DC/DC Converters provide six identical windings and are available in four sizes with five different lengths of air gap each. These transformers offer an isolation voltage of 500V_DC for the standard version and up to 1.5kV_AC for the high voltage (HV) version. By using different circuits, more than 375 transformer solutions and about 125 choke solutions possible. Other features include low leakage inductance and -40°C to +125°C operating temperature range. Würth Elektronik WE-FLEX Flexible Transformers are ideal for use in all types of switching regulators.
