Radiation-hardened power transformers for high-reliability space applications introduced by Vishay
MALVERN, Pa. – Vishay Intertechnology Inc. in Malvern, Pa., is introducing the Custom Magnetics SGTPL-2516low-profile radiation-hardened planar transformers for aerospace and defense power conversion applications.
Offering a lower cost, smaller size, and higher density than traditional planar transformers, these devices meet the requirements of MIL-STD-981 class S for high-reliability space applications.
Available with through-hole terminations and several package sizes, the devices are for use in switch-mode power supplies and DC-DC and AC-DC converters. Designed for harsh environments, the power transformers combine their MIL-STD-981 qualification with a rugged package with molded windings and high temperature operation to 130 degrees Celsius.

SGTPL-2516 transformers operate in frequencies from 80 to 300 kHz, and provide high dielectric to withstand voltage to 1500 volts AC, power of 150 Watts, and leakage inductance of 0.5 microhenries.
The transformers provide a greater copper fill factor than can be achieved with traditional planar devices, resulting in a smaller package size and improved efficiency and power density.
In addition to S level MIL-STD-981 A and B group screening, the devices are available with P level screening for design validation testing and other custom screening options.
Samples and production quantities of the transformers are available now, with lead times of eight weeks for devices with P level screening and 21 weeks for devices with S level screening. For more information contact Vishay online at www.vishay.com.
