New transformer achieves exceptional isolation and creepage/clearance distances in compact component footprint

RIVERSIDE, Calif., December 12, 2024 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced a new addition to its automotive grade, AEC-Q200 compliant flyback transformer line. The Model HVMA03F40C-ST10S flyback transformer is specifically designed to support high power density and greater efficiency in a compact form factor. Understanding the ongoing power-density support requirements of today’s automotive, industrial, and energy storage designs, Bourns continues to release families of high isolation flyback and gate drive transformers with expanded capabilities. The Model HVMA transformer’s long list of features makes it a superior solution for electric vehicles, transistor gate drives and high voltage battery management systems, as well as for isolated power across separate voltage systems in hybrid vehicles. It can also capably support high frequency Silicon Carbide, IGBT and Gallium Nitride switching elements in wide bandgap designs.

Bourns offers proven engineering expertise in the development of advanced Magnetic architectures in smaller component sizes. This latest transformer meets IEC standards for isolation and creepage/clearance distance requirements with a state-of-the-art mechanical and electrical design that helps increase system performance and safety at the same time. Offered in a 10 mm creepage surface mount package, the Model HVMA03F40C-ST10S gives designers up to 900 V working voltage with the capability to support new designs utilizing the existing platform or to help them streamline the design of new platforms. In addition, this 3-Watt flyback transformer features switching frequencies from 100 kHz to 400 kHz, and an operating temperature range of -40 °C to +155 °C.
