News Release | New Product: High Withstand Voltage DC/DC Converter Transformer for Automotive ’VER9060V’
September 10, 2025
SAGAMI ELEC CO., LTD. is pleased to announce the development of the DC/DC Converter Transformer for Automotive Equipment ‘VER9060V’ (W14.9mm×D10.0mm×H6.2mm) with sample availability starting from February 2025.
The VER9060V offers enhanced insulation performance, making it suitable for higher voltages application in xEV systems.
By adopting CTI LV.1 material for the base, the required creepage distance is reduced in accordance with IEC 60664.
The VER series achieves a low-profile compact design by efficiently utilizing the base dead space to accommodate the core, while maintaining ultra-high withstand voltage despite its smaller size.
This makes the VER9060V an ideal solution for flyback transformers in xEV inverters and battery junction boxes.
Sagami Elec will continue to expand its product lineup to meet diverse market requirements,offering a wide range of innovative solutions.
