Original Press Release:
Vishay Intertechnology Medium-Power Planar Transformer Provides Higher Efficiency, Space Savings Over Traditional Winding Technology
Device Offers Power From 1 kW to 3 kW in Compact 70 mm by 53 mm by 22 mm Size
MALVERN, Pa. – Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new planar transformer offering power from 1 kW to 3 kW in a compact 70 mm by 53 mm by 22 mm size. Compared to devices built on traditional winding technology, the Vishay Sfernice PLA51 delivers the same power transfer / conversion while offering higher efficiency and a lower weight and profile.
The device released today is optimized for DC/DC power converters, on-board chargers for electric vehicles, UPS, power control cooling units, and solar inverters. In these applications, the PLA51's high typical efficiency of > 99 % typical reduces losses, while its low profile of 22 mm saves space in subassemblies. In addition, the transformer's reduced weight of 170 g is a key parameter for power supplies in avionics applications.
Providing excellent repeatability, the PLA51 features a frequency range of 50 kHz to 400 kHz and operates over a temperature range from -55 °C to +125 °C with heatsink dissipation. Offered in full-bridge, half-bridge, and forward power supply topologies, the transformer features tapped outputs for fast and easy connection. This RoHS-compliant device is also available in custom designs upon request.
Samples of the PLA51 are available now. Production quantities will be available in Q4 2016 with lead times of 12 weeks for large orders. Pricing for U.S. delivery only starts at $12 per piece in 10,000-piece quantities.
