Product introduction

Product Introduction
Ferro-Silicon Aluminium magnetic ring inductor is one important type of magnetic ring inductor. The Ferro-Silicon Aluminium core is made of three metal powders (85% iron[Fe], 9% silicon[Si], and 6% aluminum alloy powder[Al]). It has the characteristics of high hardness and high resistivity, so that it has higher permeability than other iron powder cores when working at high frequency. Ferro-Silicon Aluminium magnetic ring is a kind of material with low loss and relatively high saturation, so it is very suitable for power factor correction circuits, as well as one-way driver applications, such as the pulse transformers and flyback transformers. Due to the near-zero magnetostriction, Ferro-Silicon Aluminium is the best choice for eliminating audible frequency noise in in-line noise filters and inductors.

Products Advantage
    1. With good DC superposition characteristic,It can work under high current state;
    2.With high saturation flux density,so it is not easy to saturate under a large magnetized fields;
    3.With a high magnetic permeability;
    4. Good magnetic stability,low temperature, high current withstand capacity, low noise; 
    5. The size is smaller.

Application
Ferro-Silicon Aluminium magnetic ring inductors are widely used in computer host board, computer power supply, power supply, phone charger, variable voltage dimmer for lighting, uninterruptible power supply (UPS), various household appliances control board and so on.
    1. Power inductors, such as the computer main boards;
    2. Power factor correction, such as power supply;
    3. Common mode filtering, such as mobile phone chargers;
    4. Current regulation, such as a lighting dimmer;
    5. Choke, such as an uninterruptible power supply;
    6. Choke coils, such as control panels for various household appliances;
    7. Differential mode filtering, such as strong industrial boards;
    8. Chokes, such as speed regulating motor control equipment.
