Iron powder core series and purposes

The magnetic ring is composed of magnetic core+plastic shell or insulating enamel, which has the function of protecting the magnetic core, moisture-proof and enhancing insulation. The magnetic ring is mainly divided into iron powder core magnetic ring, manganese zinc ferrite magnetic ring, nickel zinc ferrite magnetic ring, high magnetic flux magnetic particle core magnetic ring, iron nickel molybdenum magnetic particle core magnetic ring, iron silicon aluminum magnetic ring, amorphous magnetic ring, etc.

The iron powder core magnetic ring is generally the one with the highest frequency of use. Different coatings represent different materials, and the international standard for color coating is generally adopted. So what are the main classifications of iron powder core magnetic rings? Here are some classifications of the editor. Let's have a look

Materials: - 2 (red/transparent), - 8 (yellow/red), - 18 (green/red), - 26 (yellow/white), - 28 (gray/green), - 33 (gray/yellow), - 38 (gray/black), - 40 (green/yellow), - 45 (black), - 52 (green/blue);

Size: the outer diameter is from 30 to 400D (Note: the outer diameter is from 7.8mm to 102mm).
Size: the outer diameter is from 3.5mm to 77.8mm.

In addition to the ring shape, there are also E shape, bar shape, etc., which can also be customized according to the parameters required. They are widely used in connecting harnesses, computer mainboards, computer power supplies, power supplies, mobile phone chargers, lighting variable voltage dimmers, uninterruptible power supplies (UPS), various household appliance control boards, etc
