The Role Of The Inductor Coil

Self-adhesive Coil Division of the company in 2003, produces various types of adhesive induction coils, coils, coils, coil flat coils, stickers, and all other hollow coils, coils for IC card access control, solar swing coils, wireless chargers, mobile phone vibration motor coils, coil antenna coils, voice coils, circuits, consumer electronics, toys, industrial products, RFID, workers Industry control and other areas. The tuning of self-adhesive coils and the influence of frequency selectivity, inductors and capacitors in parallel can be composed of lc circuits. The circuit's natural oscillation frequency f0 and the AC signal frequency f are equal, the loop impedance and capacitive reactance are equal, and the electromagnetic energy in the inductor and capacitor, oscillating back and forth,lc circuit resonance phenomenon. When the harmonic impedance and capacitive reactance of the circuit are reversed, the total current of the equivalent circuit is minimum impedance, and the current is maximum (f = "f0" AC signal), the role of the lc resonant circuit can be selected at a certain frequency, f communication signal is selected.

Choke inductor

The self-induced electromotive force of an inductor always varies with the current in a self-adhesive coil. The AC effect of the inductor coil, the effect according to the size of the inductor xl, the unit is ohms. The relationship with inductance l and AC frequency f xl = 2πfl, inductance can be mainly divided into high frequency and low frequency choke coil choke. We are not unfamiliar with the coil, because we can see it in daily life, which is quite familiar to us, but we still need to pay special attention in the process of use, because it is easy to cause excessive current.
