Uses of soft ferrite
Release time: May 28,2024
The magnetic permeability of ferrite for telecommunications ranges from 750 to 2300. It has low loss factor, high quality factor Q, and stable magnetic permeability relationship with temperature/time. It is the type with the slowest magnetic permeability decrease during operation, about It decreases by 3% to 4% every 10 years. Widely used in high Q filters, tuned filters, load coils, impedance matching transformers, and proximity sensors. Broadband ferrite is often referred to as high permeability ferrite, with magnetic permeabilities of 5000, 10000, and 15000 respectively. Its characteristics are low loss factor, high magnetic permeability, and high impedance/frequency characteristics. It is widely used in common mode filters, saturated inductors, current transformers, leakage protectors, insulation transformers, signal and pulse transformers, and is widely used in broadband transformers and EMI. Power ferrite has high saturation magnetic induction intensity, which is 4000~5000Gs. In addition, it has low loss/frequency relationship and low loss/temperature relationship. In other words, as the frequency increases, the loss does not increase much; as the temperature increases, the loss changes little. Widely used in power chokes, parallel filters, switching power supply transformers, switching power supply inductors, and power factor correction circuits.
