Fixed inductors are widely used in electrical and electronic circuits for their desirable magneto-electric characteristics. 4922-45H is one type of fixed inductor. It is designed to be used in a wide range of applications, from DC to microwave frequencies. In this article, its application field and working principle will be discussed.

Applications

The 4922-45H series fixed inductors are applicable for installation in products requiring medium to high current-handling capability in both high frequency and DC circuits. It is suitable for power supply filtering, coupling, and DC/DC converters, as well as bypass and RF decoupling applications. It provides efficient protection from the harmful effects of EMI/RFI while being extremely stable and reliable under varying temperature, humidity, and other conditions.

The 4922-45H series inductors come with a variety of sizes and shapes, making them ideal for a range of applications, both indoor and outdoor. The range includes models with a maximum current rating of 40 Amps to 41 Amps, allowing for flexible design options. Thanks to their low profile and small size, they can be easily installed into tight spaces and offer improved performance. The maximum operating temperature of this series is up to +125°C.

Working Principle

The working principle of fixed inductors is based on the principle of induction. Whenever the current flowing through an inductor changes, it induces an electric flux that is linked to it. This flux produces a magnetic field which, in turn, produces a voltage. This voltage opposes the change in current, which is known as the back emf effect.

The characteristic of an inductor is described by its inductance. Inductance is the property of a device that restricts the flow of current in response to a change in voltage. A fixed inductor consists of a coil of wire that is wound in a specific manner to achieve a desired inductance. The number of turns, the shape of the winding, the wire gauge, and the material used all play a role in determining the inductance of the part.

The 4922-45H series fixed inductors are designed to achieve high inductance values with minimal power loss. They feature a heavy-duty steel construction for extended operating life and reliable performance. They use a ferrite core, which helps minimize power losses caused by non-ideal winding arrangements, resulting in improved efficiency.

Conclusion

The 4922-45H series fixed inductors are a reliable and efficient solution for a variety of applications. From power supply filtering to bypass and RF decoupling, these parts are designed to provide outstanding performance and stability. With their small size and low profile, they can be easily installed into tight spaces, making them an ideal choice for those looking for compact and reliable inductors.
