Product Description
Nanocrystalline High Rectangular Ratio cores For Leakage Current Transformer
Fe-based Nanocrystalline & Co-based Amorphous High Rectangular Ratio Magnetic Cores possess a mid and low saturation magnetic induction(Co-based Amorphous 0.58T; Fe-based Nanocrystalline 1.2T), low coercivity, low loss, excellent wear and corrosion resistance, low dependence on temperature
Typical Application:
- Magnetic Amplifier(MagAmp)
- Leakage Current Transformer
- Magnetic Sensor
- Spike Suppressor
