New Vishay Intertechnology Space-Grade Common Mode Choke Provides EMI Filtering For Gan And Sic Switching Applications

(MENAFN- GlobeNewsWire - Nasdaq) Surface-Mount Device Features a Robust Nanocrystalline Core and Overmolded, Ruggedized Construction for Reliable Performance in Harsh Environments

MALVERN, Pa., March 18, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new space-grade, surface-mount common mode choke designed to provide EMI filtering and noise suppression in demanding space, aerospace, and defense applications.

The Vishay Custom Magnetics SGCM05339 is ideal for GaN and SiC switching applications, where sharp edges develop in waveforms, causing radiated emissions. The common mode choke will also be used in low profile, high current power supplies; DC/DC converters in distributed power systems; and power converters for solar panels.

To withstand the harsh environments of these applications, the self-shielded device features a compact, robust nanocrystalline core and an overmolded ruggedized construction. The SGCM05339 offers high impedance at extended frequencies, supports high heat rating current capabilities of up to 14.43 A, and provides a continuous operating temperature range from -55 °C to +130 °C.

Outgassing compliant per ASTM-E595, the device released today is available with a wide range of screening options, including MIL-PRF-27, Grade 5, Product Level T, Temperature Class S; MIL-STD-981 Family-4, Class S; and EEE-INST-002. The SGCM05339 offers a dielectric withstand voltage of 1000 VRMS, insulation resistance of 10 GΩ (minimum) at 500 VDC, and can be customized by turn count, wire gauge, and more to meet specific application requirements.
