Super toroidal inductor core produced by Feneng

Toroidal inductor core is a kind of electronic components, the main role is a role of electromagnetic induction conversion, simple inductance can be a wire, it can be used as an antenna. It can be used in frequency selection circuit and RF transmitting circuit. Compared with the former two inductors and I inductor, it can be used for filtering and energy storage. There are common mode inductance available anti - drying effect, etc

This toroidal inductor core is a bule/green core, winding the wire to some turns to meet the requirement inductace.




The composition of fe-si-al magnetic powder core includes 85% iron (Fe),9% silicon (Si), and 6% aluminum alloy powder (Al), which has the advantages of high energy storage, high saturation flux density, high permeability C, and stable performance at high temperature. Ideal for power factor correction circuits, it is a low loss and relatively high saturation material.
Iron, silicon aluminum for distributed air-gap magnetic powder core, especially suitable for switching power supply of the energy storage. Filter inductance, the BS because of its high value and low loss, and with the volume. Compared with the iron powder core and ferrite magnetic permeability has higher energy storage capacity, so it is widely used in rotary transformer, pulse transformer, power factor correction (PFC) circuit, because of its stable performance at high temperature, can be smaller than the iron powder core, now have used for transformer used to replace iron powder core. When through the large ac voltage does not produce noise, zero magnetostrictive properties, can also be used to filter, iron, silicon aluminum magnetic powder core coating is black, The following is a look at the actual application of iron, silicon and aluminum magnetic ring inductance:
1, common mode filtering, such as mobile phone charger
2. Differential mode filtering, such as strong industrial board
3. Choke coil, such as speed-regulating motor control equipment
4, choke coil, such as various household appliances control panel
5. A choke, such as an uninterruptible power supply (UPS)
6, current regulation, such as lighting voltage dimmer
Power inductance, such as computer motherboard
8. Power factor correction, such as power supply
