Vishay Intertechnology space-grade planar transformers

Offering a lower cost, smaller size, and higher density than traditional planar transformers, customisable Vishay Custom Magnetics SGTPL-2516 series devices meet the requirements of MIL-STD-981 class S.

Available with through-hole terminations and multiple package sizes, the devices released today will be used in switch mode power supplies and DC/DC and AC/DC converters. Designed for the harshest of environments, the transformers combine their MIL-STD-981 qualification with a rugged package featuring molded windings and high temperature operation to +130 °C. SGTPL-2516 series devices operate over a frequency range from 80 kHz to 300 kHz and provide high dielectric withstand voltage to 1500 VAC, power of 150 W, and leakage inductance of 0.5 µH.

Featuring a unique winding structure and build technique, 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. The SGTPL-2516 series' winding technology allows for easy modification to meet design-specific requirements for operating voltage, inductance, power, and package size and height with no up-front tooling charges. 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.
