Digi-Key Corporation announced the signing of an exclusive global product distribution agreement with Würth Electronics Midcom. As part of the deal, Digi-Key will be the sole distributor of the company's newly developed planar transformer product series. Würth Electronics Midcom's planar series is optimized for frequencies ranging from 200kHz to 700kHz, with 500-Vdc isolation and 250 W 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 10 mm and an operating temperature range of -40°C to +125°C.

"We're pleased to be Würth'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 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.

"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, Würth 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."
