Vishay's new space-grade planar transformers offer lower cost, smaller size and higher density

Customizable transformers use unique winding structure and manufacturing process, meeting MIL-STD-981 S-level standards

MALVERN, Pennsylvania, USA, Shanghai, China — May 13, 2024 — Vishay Intertechnology, Inc. recently announced the launch of a new series of low-profile, aerospace-grade planar transformers for power conversion, the SGTPL-2516 series. Compared with traditional planar transformers, the customizable Vishay Custom Magnetics SGTPL-2516 series transformers have obvious advantages in lower cost, smaller size, higher power density, and meet MIL-STD-981 S-level requirements.

The transformers feature through-hole terminals and a variety of package sizes for wide use in switch-mode power supplies as well as DC/DC and AC/DC converters. Designed for harsh environments, these transformers feature a rugged package design with molded windings, an operating temperature up to 130 C, and are certified to MIL-STD-981. The SGTPL-2516 series transformers operate from 80 kHz to 300 kHz, have a high dielectric withstand voltage of 1500 VAC, a power of 150 W, and a leakage inductance of 0.5 H.

With a unique winding structure and manufacturing process, these transformers achieve a higher copper fill factor than traditional planar transformers, resulting in improvements in package size, efficiency, and power density. The winding technology of the SGTPL-2516 series makes it easy to adjust the operating voltage, inductance, power, package size, and height to specific design needs without paying upfront tooling costs. In addition to MIL-STD-981 standard S-level Group A and Group B screening, these devices also offer P-level screening for design verification testing and other customized screening options.

Samples and production quantities of the new transformers are available now, with lead times of eight weeks for P-class equipment and 21 weeks for S-class equipment.
