Product Description
Product Overview
The PLN Series Planar Transformers are designed for DC-DC transformer applications, offering power ratings from 48 to 70 watts. These transformers utilize a forward converter topology, featuring low leakage inductance and a low-profile, surface-mount component. They are engineered for reliable operation across a wide temperature range of -40 C to +125 C and are RoHS compliant. Ideal for demanding applications such as PoE, industrial power systems, switched-mode power supplies (SMPS), LED lighting, and battery management systems, the PLN Series provides efficient and compact power conversion solutions.
