Vishay Launches Space-Grade Choke Amid GaN/SiC Power Electronics Growth
Event summary
- Vishay Intertechnology released the SGCM05339, a new space-grade common mode choke.
- The device is designed for GaN and SiC switching applications, targeting EMI filtering and noise suppression.
- The SGCM05339 features a nanocrystalline core, ruggedized construction, and supports a wide operating temperature range (-55 °C to +130 °C).
- Lead times are currently estimated at 8 to 12 weeks.
- The device is compliant with ASTM-E595 outgassing standards and offers customizable screening options.
The big picture
The launch of the SGCM05339 underscores the growing demand for specialized components in the space sector, driven by increasing satellite constellations and advanced military applications. GaN and SiC semiconductors are increasingly replacing silicon in power electronics due to their efficiency and power density, but require specialized EMI filtering solutions like this choke. Vishay's ability to capitalize on this trend will be a key indicator of its performance in a niche but strategically important market.
What we're watching
- Market Adoption
- The success of this choke will hinge on the broader adoption rate of GaN and SiC power electronics in space applications, which is currently constrained by cost and reliability concerns.
- Competitive Landscape
- Competition in the space-grade component market is limited, but Vishay's pricing and customization options will be critical in securing contracts against smaller, specialized suppliers.
- Supply Chain
- The 8-12 week lead time suggests potential supply chain constraints, and whether Vishay can maintain this timeline amidst broader geopolitical uncertainties warrants monitoring.
