Electronics Power Supply / Management Engineering Supply Chain Transformer transformerWURTH ELEKTRONIK WE-FLEX HV (Flexible Transformer High Voltage) line of transformers for SMT assembly deliver flexible capabilities in various applications making them suitable for fast prototyping. Different circuit configurations enable more than 375 transformer solutions and around 125 choke solutions. Applications include flyback converters, forward converters, push-pull converters, step-up and step-down converters or single-ended primary-inductor converters (SEPIC). With their isolation voltage of 1.5kVac, these transformers are currently unrivaled on the market. The newly developed MnZn core material reduces core losses by up to 30% as compared with classical products – available in four sizes, each with five different air gap lengths. The working temperature is specified as -40°C to +125°C.
