ER19/4.8/15 Planar Transformer is designed for high-frequency power conversion systems requiring low-profile structure, high power density, and excellent thermal performance. Utilizing planar transformer technology, it provides efficient energy transfer and improved winding consistency for modern compact power architectures.
Its planar magnetic structure significantly reduces transformer height while supporting stable high-frequency operation, making it ideal for high-density SMPS, telecom power systems, and industrial electronic applications.
Compared with conventional wire-wound transformers, planar transformers offer lower leakage inductance, improved thermal management, and better repeatability in mass production environments.
Customized turns ratios, PCB winding layouts, insulation structures, and pin configurations are available according to specific application requirements.
