In view of the fact that some customers said there was a problem with the parameter identification Here is a remark：Inductance indicated above They are all accurate values tested by bridge，The current value is the rated current value calculated according to the wire diameter。But the inductance is linear According to the increase of current，The inductance is reduced，The inductance values indicated above are no-load values，For inductance current with load value, please contact the seller for customization。thank you
Selection of magnetic core materials：
becauseLoss of magnetic powder core material、The anti saturation performance is better than that of iron powder core（be commonly called：Yellow white ring magnetic ring），And iron powder core（Huang Baihuan）Generally, it can only work in medium and low frequency（commonly5kHzfollowing，And the loss is large）。therefore，The magnetic ring inductors designed by our shop are all made of iron, silicon and aluminum、High flux orMPPMaterial Science（International core brandCSCOr magneto）。The inductor made of Fe Si Al magnetic core has high comprehensive cost performance；The volume of inductor with high flux core is small，But the price is higher；MPPThe volume of the core winding inductor takes the second place，Low loss（Fe Si Al、The loss of high flux is also relatively small），But it's expensive。All three materials can work up to500kHzHarmonic frequency of。
