Powering Resilience: Vishay's New Transformers Secure Supply Chains & Shrink Space Electronics

By Ruth Flores

Malvern, PA – In an era defined by escalating geopolitical instability and a burgeoning space sector, reliable component sourcing and technological innovation are paramount. Vishay Intertechnology is responding with the launch of its SGTPL-28 series, a new line of 150W, space-grade planar transformers designed for demanding applications in avionics, military, and space (AMS). While the announcement details a technical leap forward, a closer look reveals a strategic move addressing crucial supply chain vulnerabilities and pushing the boundaries of power density in critical electronic systems.

These transformers aren’t simply about more power; they represent a calculated effort to enhance resilience in the AMS supply chain, a sector increasingly vulnerable to disruptions. "The recent global events have highlighted the fragility of international supply chains. Companies are actively seeking domestic or near-shore sourcing options, especially for mission-critical components,” says an industry analyst specializing in defense electronics. “Vishay’s investment in domestic manufacturing capacity for these transformers is a smart move.”

Addressing a Critical Need

The SGTPL-28 series stands out due to its optimized design for 28V input forward converters, a common power architecture in AMS applications. Traditional planar transformers often struggle to balance size, weight, and performance. Vishay claims its new series overcomes these limitations, offering up to 40% greater winding fill, leading to a smaller footprint and improved efficiency.

“The reduction in size and weight is significant,” explains a lead engineer at a satellite manufacturer who wished to remain anonymous. “In space applications, every gram counts. Reducing the weight of power conversion components allows us to increase payload capacity or reduce launch costs.”

Beyond the physical benefits, the transformers’ compliance with stringent military standards – including MIL-PRF-27 and MIL-STD-981 – is a key differentiator. Achieving these certifications requires rigorous testing and quality control, assuring customers of the components’ reliability in harsh operating environments. Vishay’s commitment to these standards directly addresses concerns about counterfeit parts and substandard components infiltrating the AMS supply chain.

The Supply Chain Imperative

The aerospace and defense industries have long relied on complex, globally distributed supply chains. However, recent events – including trade disputes, pandemics, and geopolitical conflicts – have exposed the inherent risks associated with this model. The drive for greater supply chain resilience is now a top priority for governments and companies alike.

“There’s a growing awareness that over-reliance on single suppliers or geographically concentrated manufacturing can create significant vulnerabilities,” explains another defense industry source. “Companies are diversifying their sourcing strategies, building up domestic capabilities, and investing in technologies that enhance supply chain visibility and traceability.”

Vishay’s domestic manufacturing capacity for the SGTPL-28 series aligns with this trend. By bringing production closer to key customers, the company can reduce lead times, mitigate risks associated with international shipping, and ensure a more secure supply of critical components.

Shrinking Footprints, Boosting Performance

While supply chain security is a crucial aspect of the SGTPL-28 series, the technology itself also delivers significant performance benefits. The smaller size and increased power density of the transformers enable designers to create more compact and efficient electronic systems.

“We’re seeing a constant push for miniaturization in avionics and spacecraft,” says a lead engineer at a major aerospace company. “Every square inch of space is valuable. These transformers allow us to pack more functionality into a smaller volume, which is essential for modern designs.”

The increased power density also translates into improved thermal performance. By reducing heat generation and improving heat dissipation, the transformers contribute to the overall reliability and longevity of electronic systems.

Beyond the Specs: Customization and Future Trends

Vishay is offering the SGTPL-28 series with customizable options to meet specific customer requirements. This flexibility is crucial in the AMS sector, where applications often demand tailored solutions.

Looking ahead, the demand for high-performance, reliable power components in the AMS sector is expected to grow. Driven by factors such as the expansion of satellite constellations, the development of advanced aircraft, and the increasing use of autonomous systems, the need for innovative power solutions will only intensify.

"We anticipate continued innovation in materials science and power conversion technologies,” says an industry analyst. “Components that can deliver higher power density, improved efficiency, and greater reliability will be in high demand.”

The SGTPL-28 series represents a significant step forward in this direction, combining robust design, stringent quality control, and a strategic focus on supply chain resilience. As the AMS sector continues to evolve, Vishay’s commitment to innovation and reliability will undoubtedly play a crucial role in shaping the future of aerospace and defense technology.
