Choke Flow Coils-2
The choke coils with a wire rod-type core, drum-type core, magnetic ring core as well as the EI-type core l, can be used for a variety of machines. EI type core is most suitable for switch power supply.
1) Good quality and high self-resonance frequency (with wire rod)
2) Larger induced current (drum-type core)
3) For higher current magnetic and less flux leakage (ring core)
