Magnetic Powder Cores Series are coated by improved epoxy that can resist high temperature up to grade,The coating also complies with the requirement of environmental protection and RoHS.The finishing has a minimum dielectric strength of 600Vrms at 50Hz and can resist most cleaning solvents.However,extended exposures to certain solvents may have detrimental effects.
The method of testing the insulation strength of the surfacing coating:put two electroplates on tne corners of the cores'two surfaces,app;ies 50Hz,1250Vrms and last for 5 seconds.
RAS Series Super SendustFe-Si-Al alloy powder core composed of 85% Fe, 9.6% Si, 5.4% Al
Magnetostriction coefficient close to zero
