Designed for high-frequency switching environments, the EI22 transformer delivers excellent thermal and efficiency performance:
Low core loss under high-frequency operation
Controlled temperature rise during continuous load
Improved heat dissipation due to larger core size
Typical high-frequency transformers operate efficiently within tens to hundreds of kHz, ensuring stable performance in SMPS systems.
The EI22 high-frequency transformer is suitable for a wide range of medium-power applications:
Switching mode power supplies (SMPS)
DC-DC converters and power modules
LED drivers and lighting systems
Industrial control equipment
Consumer electronics and home appliances
Its versatility makes it a preferred choice for both industrial and commercial power designs.
