Iron Dust Core/iron powder core/soft iron core
General Description
Iron powder cores/iron dust cores may come in numerous sizes and configuration, each of which is available in different materials. However the toroidal cores are the most efficient configurations due to its highly shelf-shielding characteristic. Iron powder toroidal core is seldem necessary to shield a toroidal inductor as most of the flux lines are contained within the core.
Characteristics:
1. Lowest costs.
2. Good for low frequency application (<100 khz).
3. High maximum flux density: 15,000 guass.
4. Inductance tolerance: ≤10%.
