Fixed inductors are components that store electric energy when a higher input voltage or current is applied to them. In this article we\'ll discuss the application field and working principle of 4922-31L, a fixed inductor used in a variety of electronics products.

What is the 4922-31L?

The 4922-31L is an electrical component used as a fixed inductor. It is a product of Yageo, a global provider of electronic parts and components. The 4922-31L is categorized as an “Axial Power Inductor” with a high saturation current rating.

The 4922-31L is a two terminal component with an axial lead type, and is available in two form factors: one with a solderable lead and one with a through-hole lead. While the solderable lead is made of lead-free silver, the through-hole lead is constructed of phosphor bronze. It has a wide inductance range from 0.006 to 10uH, and can store up to 845mA of current at 25°C.

4922-31L Application Field

The 4922-31L is widely used in power and audio applications, as it is specially designed to withstand high temperature and high currents. It is used in systems such as switching regulators, voltage regulators, DC/DC converters, EMI filters, audio equipment, and telecom circuits. It can also be used for power inductors, RF filters, electronic ballast, and motor control.

Working Principle

The principle of operation of the 4922-39L can be described in two parts: the storing of energy and the ability to regulate the current or provide a path for the current.

When an input voltage or current is applied to the 4922-39L, it stores this energy in the form of a magnetic field. This stored energy can be released later when the voltage or current is removed. In this way, the 4922-39L acts as an energy buffer, allowing for a smooth transition in the current or voltage during switching or high-frequency signal paths.

The 4922-39L also acts as a regulator to provide a path for the current. The ability of the 4922-39L to regulate the current is crucial in preventing devices from being damaged by high-frequency or large amounts of static current. The inductor can also be used in circuits to prevent signal distortion, attenuate noise, and control current in order to reduce power consumption.

Conclusion

The 4922-31L fixed inductor is a versatile component that can be used in power, audio, and telecom applications. It stores energy in the form of a magnetic field when current is applied to it, and then releases the energy when the current is removed. It can also be used to regulate current or provide a path for the current, helping to protect devices from damage and reducing power consumption.
