Vishay Sfernice PLA51 Planar Transformer Now a Featured Item at New Yorker Electronics

NORTHVALE, NEW JERSEY – Vishay Intertechnology’s Planar Transformer – offering power from 1kW to 3kW in a compact 70mm x 53mm x 22mm size – is now being distributed by New Yorker Electronics. Compared to devices built on traditional winding technology, the Vishay Sfernice PLA51 delivers the same power transfer and conversion while offering higher efficiency and a lower weight and profile.

The high efficiency reduces losses while the low profile saves space in sub-assemblies. It’s also low in weight, a key parameter for power supplies in avionics applications. The Sfernice PLA51 Planar Transformers provide high efficiency above 99% typical in DC/DC power converters, on-board chargers for electric vehicles, power-control cooling units and solar inverters.

Vishay Sfernice PLA51 Planar Transformers are designed for switch mode power supply applications (in transformers and choke inductors). By using the supplied software, the end user can configure the final transformer device. Tapped outputs provide fast and easy connection.
