Product Overview
The PLN0xx-ER20 Series is a range of planar transformers designed for DC to DC conversion, offering power ratings from 60 to 71 watts. Utilizing a flyback converter topology, these transformers feature low leakage inductance and a low-profile, surface-mount design. They operate efficiently across a wide temperature range of -40 C to +125 C and are RoHS compliant. Ideal for high-power PoE applications, industrial power systems, switched-mode power supplies (SMPS), LED lighting, and battery management systems, these transformers provide reliable power conversion solutions.
