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.

FAQ

Q: How do these differ from standard Power Inductors?
A: Designed for signal transfer (not energy storage), with lower coupling capacitance and higher isolation than Power Inductor.

Q: Suitable for high-frequency SMPS designs?
A: Yes, optimized for 20kHz–100kHz operation.

Q: Custom ratios available?
A: Multiple standard configurations; contact for custom Transformer.
