High Current Toroidal Power Inductor 20a 200u 470uh Customized
Inductance is mainly filter, oscillation, delay, notch, the image saying: "pass DC, block AC". The magnetic beads are mainly used to suppress electrical radiation interference, high-frequency noise and spike interference, and absorb ultra-high-frequency signals. They are often used in PCBs, DC/DC modules, high-frequency switches, switching audio amplifiers, data lines, power lines, and signal lines. Wait.
1. The frequency characteristics of the magnetic bead and the
inductor are different. In the low frequency band, the inductance
of the magnetic bead increases, the resistance of the winding
inductance decreases, and the inductance of the magnetic bead
works, which can be regarded as a low-loss, high-Q value. Inductor;
at high frequency, the inductance of the magnetic bead becomes
smaller and the resistance value becomes larger, resulting in an
increase in the total impedance, which can be regarded as a
high-frequency blocking device.
2. The selection of the size of the magnetic ring inductance
magnetic beads completely depends on the frequency and strength of
the interference wave that needs to be absorbed. The main
parameters based on: impedance (unit is Ω), DC resistance (unit is
mΩ) and rated current (unit is mA) at a frequency of 100MHz.
