Soft magnets
| The magnets have very extensive application fields, such as deflection yokes of CRT、 power switch transformer 、 retro- sweeping transformers of TV、radio antennas、chokes、rotary transformers of AV machines、allots of energy-saving lights、ransformer、etc. The main category is ring,"U" core, "E" core,"EI" core, "EE" core & Deflection Yokeswith the magnetic values R350、R1K、R2KD、 R2KBD、R2KB、R4KB、R5K、R7K. |
