MEAN WELL introduces two new series of SMD 1W unregulated DC-DC converters, the single output SFTN01 and dual output DETN01. The new series feature a wider operating temperature range of -40 - +90°C, and higher efficiency (max. 83%) compared to previous models. Pin assignments match the previous models so that PCB terminal systems do not need to be redesigned to accommodate them. Applications include IoT, telecom and networking, industrial control, and distributed power architectures.
