Inductance Coil
Inductance Coil
Product Classification
Inductance type: fixed inductance, variable inductance. Classification according to the properties of the magnetic body: hollow coil, ferrite coil, iron coil, copper coil.
Classification according to the nature of work: antenna coil, oscillation coil, choke coil, trap coil, deflection coil.
According to the winding structure classification: single coil, multi-layer coil, honeycomb coil, close winding coil, interwinding coil, spin-off coil, disorderly winding coil.
Product Features
The electrical characteristics of inductors are the opposite of those of capacitors: "pass low frequency and resist high frequency". When high- frequency signals pass through the inductor coil, they will encounter great resistance, which is difficult to pass through; while the resistance presented by low-frequency signals when passing through it is relatively small, that is, low-frequency signals can pass through it more easily. The inductor coil has almost zero resistance to direct current. Resistance, capacitance and inductance, they all present a certain resistance to the flow of electrical signals in the circuit, this resistance is called "impedance". The impedance of an inductor coil to a current signal utilizes the coil's self-inductance.
