Digi-Key has cornered an exclusive sole distributorship of Wurth Electronics Midcom’s newly developed planar transformer product series, as part of a broader global agreement.

“We’re pleased to be Wurth’s partner of choice for the Planar Transformer line,” said Tom Busher, vice president of global interconnect, passives, and electromechanical product for Digi-Key. “They have created a product that offers a smaller form factor along with increased levels of productivity – attributes of increasing importance to today’s electronic component buyer.”

The patent-pending Planar product design offers many advantages compared to traditional bobbin-wound products including reduced size and weight, high efficiency, low leakage, consistent parasitics, and excellent thermal characteristics. Using pre-formed flatwires yields significant cost reductions compared to existing stacked layer and multilayer PCB designs.

Wurth Electronics Midcom’s planar series is optimised 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.

“To best respond to customer demand for the planar product line, we are confident in Digi-Key’s ability to deliver,” said Dominik Kern, president, Wurth Electronics Midcom. “We need a partner we can rely upon to have product on the shelf for immediate delivery while offering a high level of specialized services designed to support the challenges of the design engineer.”
