Transformers

Transformers

Custom transformers are critical components for a wide range of applications, offering versatility in power conversion, voltage regulation, and impedance matching. Sigma’s high-frequency transformers are designed for various configurations, including power, step-up/step-down, autotransformers, flyback, impedance matching, and telemetry. Their designs feature multiple core architectures such as toroid, pot core, E-core, RM core, C-core, and planar, allowing for tailored solutions to meet specific operational needs.

Engineered for Extreme Environments

These transformers are engineered to operate across a broad size range and can withstand extreme temperature conditions up to 300˚C, ensuring reliable performance in demanding environments. With the capacity to handle high voltages, Sigma’s transformers provide robust and efficient power management solutions.

Manufactured to the highest quality standards

Each custom assembly follows detailed written procedures, ensuring precision at every stage. The manufacturing process is video documented for customer transparency and thorough testing is conducted to ensure top performance and reliability. Sigma is proud to be ISO 9001 certified ensuring carefully documented processes and quality procedures.
