Wurth Electronics Midcom Introduces Planar Transformer Series
The series is optimized for frequencies ranging from 200kHz to 700kHz, with 500VDC isolation and 250W power handling capabilities. Developed to be fully customizable to individual customer needs, the planar SMD transformers comes in multiple turns ratio options with optional Aux winding for maximum flexibility. The parts have a low-profile height of 10mm and an operating temperature range of -40°C to +125°C.
The patent-pending design offers a multitude of advantages compared to traditional bobbin-wound products including reduced size and weight, high efficiency, low leakage, consistent parasitics and excellent thermal characteristics. The innovative use of pre-formed flatwires yields significant cost reductions compared to existing stacked layer and multilayer PCB designs.
