Magnetic Powder Core for EV Charger

Magnetic Powder Core for EV Charger

Sendust Core is made from 6%Al,9%Si and 85%Fe. It is mainly used to replace iron powder core as its core loss is 80% less than the powdered iron, so it can be applied with the frequency above 8kHz.

Sendust Cores(AS):

Sendust Core is made from 6%Al,9%Si and 85%Fe. It is mainly used to replace iron powder core as its core loss is 80% less than the powdered iron, so it can be applied with the frequency above 8kHz. Sendust core has a saturation flux density of 1.05T and permeability from 14 to 250 . The nearly zero magnetostriction alloy makes sendust ideal for eliminating audible frequency noise. It is mainly applied in AC inductor, output inductor, in-line filter, power factor correction inductor etc. It can also be used as transformer core in some circumstances.
