About Sigma Electronics Inc
Sigma Electronics has operated from Houston, Texas for over 45 years as a family-owned business specializing in custom wire-wound magnetics. The company is led by President and CEO Dan Japhet Jr., a Houston resident with a finance and oil-and-gas background who has held the role for 12 years after investing alongside a group of investors and board members. Engineering and production are directed by Jose Guerrero, who brings 15 years at Sigma and an electronics engineering degree from Texas Southern University. The 35,000-square-foot Houston facility houses a skilled workforce that produces transformers, inductors, chokes, custom coils, and value-added assemblies. With over 10,000 unique designs in its library, Sigma serves extreme-environment applications requiring operation up to 300°C and high pressures. The company offers fast-track engineering samples, typically delivered in two to three weeks, and maintains an ISO 9001-certified quality system supported by documented training programs for manufacturing associates. Sigma’s customer base spans oilfield services (downhole tools), commercial space (NewSpace), defense (meeting MI-T-27E specifications), industrial manufacturing (power generation, chemical, primary metals), and alternative energy (wind and solar). Long-term relationships with major oilfield service companies anchor the business, while defense and space programs rely on the same ruggedized magnetic components proven in downhole conditions. The company emphasizes design retention, allowing customers to keep ownership of their intellectual property throughout the product lifecycle. Video-documented manufacturing procedures provide transparency, and a commitment to personalized technical support underpins its guarantee of reliable service.
