IGBT Drive Transformers

IGBT Drive Transformers

• Key Features
  Engineered for robust performance in variable-frequency drives, these gate drive transformers deliver reinforced insulation and ultra-low coupling capacitance (as low as 2.5pF) for critical IGBT switching control. Featuring nanocrystalline toroidal cores, they achieve high corona extinction voltage and compact THT/SMT designs saving PCB space. With operating frequencies up to 100kHz and transmittable power up to 42W, they ensure precise pulse transmission. Fully enclosed construction provides mechanical durability and RoHS compliance. Optimized for synergy with EMC Filter in high-noise industrial environments.
