Color ring inductors have important applications in radio technology and other production technologies. In the circuit, the inductor (color ring inductor) often forms a resonant circuit, a filter circuit, and the like together with the capacitor. The basic working principle of the color ring inductor is charging and discharging, of course, rectification, oscillation and other functions. The color ring inductor is generally used for circuit matching and signal quality control, and the general connection and power supply connection is also an energy storage element.
The role of color code inductance
1. There is a layer of insulating material between the two conductors of the color code inductor. The charge cannot pass, and the conductors on both sides accumulate the opposite charge under the action of the electric field. If it is DC, there will be no more current after charging. DC-blocking effect. If AC power is applied, due to the charge and discharge of the capacitor, the charging charge will change from time to time with the voltage direction. The current will change, and the charge will be charged as if the current passed through the capacitor. This is coupling.
2. The tuning loop is a parallel loop of color code inductors. The current of the color code inductor cannot jump. When there is no voltage outside, the loop has current flowing to the capacitor. The potential of the color code inductor can be released, and the capacitor is charged. Then, the inductor is discharged, and the inductor is reversely charged to the capacitor. This forms an oscillation. If the external signal frequency is equal to the oscillation frequency of the loop, it causes resonance, and the electric power is called resonance.
3, can be used to select the frequency, used for tuning and filtering. What happens in this loop is the potential energy (in the inductor) variable electric field energy (in the capacitor). The electric field energy (in the capacitor) variable potential energy (in the inductor The delay is to use the string resistor in the capacitor charging loop to limit the charging current and reach the delay necessary to fully charge the capacitor.
4. Color code inductance (or inductance) is the physical quantity that characterizes the ability of the inductor to hold charge. The amount of electricity we need to increase the potential difference between the two plates of the inductor by one volt is called the capacitance of the capacitor. Color code inductor is physics, it is a static charge storage medium (just like a bucket, you can charge the charge into, in the absence of a discharge loop [1], the dielectric leakage self-discharge The effect/color code inductance is significant, and the possible charge is permanent, which is its characteristic. It is widely used, and it is an indispensable electronic component in the field of electronics and power. Mainly used in power supply filtering, signal filtering, signal coupling, resonance, DC blocking and other circuits.
