Features
1. The magnetic core is welded to a whole by argon arc welding process
2. Ferrite core of silicon steel has its own air gap
3. Epoxy resin potting process
4. Laser coding
Advantages
1. The iron core welding process ensures good saturation characteristics and reduces noise caused by the iron core resonance
2. Potting with epoxy resin, iron core additionally wrapped with cured resin reduces noise generated by resonance.
3. Low no-load current, low loss
4. Good impedance
