Product Description

Hollow inductor Custom 5UH audio power amplifier inductor coli three-layer horizontal QZ copper wire wound inductor

1.function

blocking effect

The self-induced electromotive force in the coil is always resistant to changes in the current in the coil. The hollow coil has a blocking effect on the AC current, and the size of the blocking effect is called the inductive reactance xl, and the unit is ohms. It is related to the inductance l and the AC frequency f by xl=2πfl.

tuning and frequency selection

lc tuning circuit can be formed by connecting hollow coil and capacitor in parallel. That is, the natural oscillation frequency f0 of the circuit is equal to the frequency f of the non-AC signal, then the inductive reactance and capacitive reactance of the circuit are equal, so the electromagnetic energy oscillates back and forth in the inductor and capacitor, which is the resonance phenomenon of the lc circuit. When resonant, the inductive reactance and capacitive reactance of the circuit are equivalent and reverse, the inductive reactance of the total current of the circuit is minimum, and the current flow is maximum (refers to the AC signal of f= "f0"), and the lc resonant circuit has the effect of selecting the frequency, which can select the AC signal of a certain frequency f.
