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.
