Soft magnets

The magnets have very extensive application fields, such as deflection yokes of CRTpower switch transformer retro- sweeping transformers of TVradio antennaschokesrotary transformers of AV machinesallots of energy-saving lightsransformeretc. The main category is ring,"U" core, "E" core,"EI" core, "EE" core & Deflection Yokeswith the magnetic values R350R1KR2KDR2KBDR2KBR4KBR5KR7K.
