Introduction

Fixed inductors, also known as Fixed-Value or Fixed-Value Resistors, are electronic components used in electronic circuits to regulate current along a voltage source or return pathway. They can also be used to produce predetermined voltages and/or different frequencies. The 5022-204F is a type of fixed inductor produced by Murata, which is suitable for audio, switching and other applications.

Application Field

The 5022-204F fixed inductor is commonly used in audio and switching applications. It offers high inductance and low resistance, making it ideal for audio applications by providing the necessary electrical energy for speaker coils, ensuring the preservation of low level audio signals during signal transmission. Its low resistance is also beneficial in switching applications, as fewer power supplies are needed for the same amount of current, resulting in reduced power loss and improved efficiency.

Working Principle

The 5022-204F fixed inductor operates on the principle of inductance. This means that when a current is applied to the inductor, it will generate a magnetic field that builds up around the inductor, resulting in an increase in the inductance of the inductor. This magnetic field will cause the inductor to oppose any changes in the current passing through it, thus maintaining a constant voltage level. This implies that the inductor stores energy in its magnetic field, and releases it as the current is changed.

Types

The 5022-204F fixed inductors are available in two types: axial and radial. The type of inductor is determined by its mounting configuration. Axial inductors have terminals on either end, while radial inductors have terminals on the side. The design of the inductor also affects its performance in different circuits. Axial inductors typically offer higher inductance values while radial types are desirable for space-constrained applications.

Performance Parameters

The performance parameters of the 5022-204F fixed inductors include the inductance range, rated current, rated voltage, resonance frequency, and self-resonance frequency. The inductance range of the 5022-204F fixed inductors is between 0.22 uF and 1.8 mH. The rated current is the maximum amount of current that the inductor can handle without any significant damage. The rated voltage is the maximum voltage that can be applied to the inductor without damaging it. The resonance frequency is the frequency at which current oscillates around the inductor’s coil, while the self-resonance frequency is the natural frequency at which current oscillates when no external load is applied.

Conclusion

The 5022-204F fixed inductor is a type of fixed inductor produced by Murata for audio and switching applications. It has a high inductance and low resistance, making it suitable for maintaining low level audio signals and reducing power loss in switching applications. It is available in axial and radial types, and has various performance parameters, such as inductance range, rated current, rated voltage, resonance frequency, and self-resonance frequency.
