magnetic powder core Product Description
Fe-Si-Al series of magnetic powder core is composed of Fe-Si-Al alloy, it has excellent magnetic characteristics, low-loss power, high magnetic flux density (Bs). When using in the temperature range of -55℃~+125℃, it has high reliability of heat resistance, humidity resistance, vibration resistance and so on;
Meanwhile, the customer can choose the wideband magnetic permeability range from 60 to 160. Sendust core has better cost performance too.
Ferrite Transformer Core Feature
magnetostriction,lower cost than MPP cores.
Soft Magnetic Powder Coil Toroid Core Application
- In line noise filters
- Pulse and flyback transformers
- Power Factor Correction (PFC)
- Switching amplifier
- AC/ DC filters
- Energy storage inductorsand so on
