News Release | New Product: DC/DC Converter Transformer for Automotive ’VER9012V’
September 10, 2025
SAGAMI ELEC CO., LTD. is pleased to announce the development of the DC/DC Converter Transformer for Automotive Equipment ’VER9012V’ (W10.0mm×D14.8mm×H12.5mm) with sample availability starting from May 2025.
The VER9012V delivers ultra-high dielectric strength of AC 4000 Vrms and achieves high inductance, all while maintaining a compact footprint of approximately 10 mm × 15 mm.
With its taller design, the VER9012V provides about five times the inductance of the comparable VER9060 series, without increasing DCR.This makes it an ideal solution for applications requiring stable output voltage and minimal ripple.
Sagami Elec will continue to expand its product lineup to meet diverse market requirements, offering a wide range of innovative solutions.
