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 500VDC for the standard version and up to 1.5kVAC 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.
