Description
ER high frequency transformer
Our ER High Frequency Transformer is widely used in SMPS switching power supply, featuring compact ER ferrite core, low leakage inductance, high conversion efficiency and stable temperature rise. Custom winding, pin layout and insulation grade are available for industrial, consumer and medical power equipment.
Core Characteristics of ER High Frequency Transformer
- Compact ER ferrite core structure, save PCB installation space
- Ultra-low leakage inductance, reduce circuit noise and EMI interference
- High saturation flux density, support large current output
- Low core loss, high energy conversion efficiency, less heat generation
- Multiple insulation grades (Class B/F/H) to meet safety standards
- Wide operating frequency range from 20kHz to 500kHz
- Custom turns ratio, inductance and power from 1W to 200W
