Je höher die Permeabilität des Magneten Ringinduktivität, the lower the temperature it can withstand. If the inductance of the magnetic Ringinduktivität is very high, the number of winding coils of the inductor can be reduced, and the large wire diameter copper wire winding system can be used.
Choose the appropriate magnetic core according to your own needs, but the core selection principle of magnetic Ringinduktivität is generally unchanged, there are the following points.

1. Die Größe der Magnetring sollte vollständig und glatt sein, ohne Vorsprünge, und je länger, desto besser.
2. Je näher die Öffnung des Magnetkerns am Kabeldurchgang liegt, desto besser.

3. Im Niederfrequenzband werden 2-3 Umdrehungen empfohlen. Im Hochfrequenzband sind keine Wendungen erlaubt.
What is the relationship between the color of a Magnetring and its material?
Most of the Magnetrings need to be painted to facilitate the difference. Generally, iron powder core is distinguished by two colors, commonly used are red/transparent, yellow/red, green/red, green/blue and yellow/white, manganese core ring is generally painted green, iron silicon aluminum is generally all black and so on.
In fact, the color of the Magnetring after firing has no inevitable relationship with the coating dyeing after spraying, but it is just an agreement in the industry.
For example, green represents a high-permeability Magnetring;
The double color represents the iron powder core Magnetring;
Black represents iron silicon aluminum Magnetring and so on.
