Fixed inductors refer to components in the circuit that are composed of winding core and other accessories. The main function of these components is to store the elastic energy of the magnetic field generated by the current. 5022-821H is a type of fixed inductor which is widely used. This article will mainly focus on its application field and working principle.

Application Field

5022-821H series are available in SMD packages with a number of performance options for extreme temperature, vibration, and noise applications. With their high impedance, stable electrical performance and steady inductance, they are mostly used in board level power supplies, automotive electronics, portable device, base station and 5G telecom circuits to filter and reduce voltage ripple.

Working Principle

The basic working principle of 5022-821H is based on Faraday\'s Law of Electromagnetic Induction. When an AC or DC current flows through the circuit, a magnetic field is generated and the magnetic energy is stored in the form of current. Then as the current changes, a voltage will be generated at both ends of the inductor. This allows inductors to act like a voltage-limiting element that both filters and reduces voltage ripple, making them ideal for a wide range of applications.

Conclusion

5022-821H are fixed inductors widely used for EMI and EMC mitigation, filtering and voltage reduction. Their surface-mount package makes them easy to install and integrate into the circuit, while their stable inductance and high impedance ensure reliable performance in a wide variety of applications. With their useful functions and excellent features, 5022-821H are the perfect choice for board level power supplies, automotive electronics, and 5G telecom circuits.
