Iron Dust Core
The basic raw materials for Iron Dust Core are a high purity electrolytic iron or iron alloy, in powder form. Conventional powder compacting technology is used in compacting core bodies. Function of material is to absorb noise emitted from electronics or electrical devices and also acts as a choke body. As compared to soft ferrites, these cores have higher saturation flux density, high curie temperature, excellent DC biasing characteristics. Almost all core bodies are produced in various sizes of toroids, having close magnetic circuit, making low leakage of magnetic flux. Core bodies are coated with epoxy resin, making core bodies resistant to humidity and high surface electrical resistance.
1. They maintain high saturation flux density and can be used with large currents.
2.Toroids - limits hum and magnetic flux leakages.
3.Their temperature characteristics are excellent and exhibit linearity.'
4.Suitable as choke coils for preventing noise in switching power sources.
5. Excellent noise suppression performance particularly very suitable where noise is emitted from the circuits in which thyristers are used.
