Fixed inductors are among the most commonly used electrical components. They are used in many applications as current and voltage limiting devices. One particular type of inductor, the 4922R-10L, is designed for use in precision timing and switching applications. In this article, we will discuss the application field and working principle of the 4922R-10L.

Application Field

The 4922R-10L inductors are primarily used in precision timing and switching circuits. As the name implies, precision timing circuits require exact timing between two devices and a high degree of stability over time. Time-varying signals such as digital clocks are an example of precision timing circuits.

In switching circuits, the 4922R-10L inductors are used as current-limiting components. The inductor creates an opposing magnetic field that can reduce the current in the circuit. This is particularly useful when power supplies are over-stressed and could risk destroying components due to the high current. The inductor limits the current before it can damage the other components.

Working Principle

The 4922R-10L inductors work on the principles of magnetism and Faraday’s law of induction. Faraday’s law states that if a magnetic field is changing around a conductor, then a voltage will be induced in the conductor. The inductor itself consists of a coil of wire with an insulating material wrapped around it. When the coil is connected to a voltage, a magnetic field is created around the coil and this causes a voltage to be induced in the coil.

This voltage is used to limit the current in the circuit. When the current starts to increase, the magnetic field increases and the voltage induced in the coil also increases which then limits the current in the circuit. When the current decreases, the magnetic field decreases and the voltage drops, allowing more current to flow.

Conclusion

The 4922R-10L inductors are fixed inductors that are designed to be used in precision timing and switching circuits. They work on the principles of magnetism and Faraday’s law of induction in order to limit the current in the circuit. By limiting the current, the inductor prevents damage to other components in the circuit and prevents the system from being over-stressed.
