Fixed Inductors

Inductors are electronic components that store energy in the form of a magnetic field when a current passes through the wire element. Fixed inductors are designed for use in constant frequency applications, such as oscillators, filters and timing circuits. A popular type of fixed inductor is the 2020R-28H, which is designed for use in applications requiring a current rating up to an ampere value.

Application Field

The 2020R-28H is most commonly used for matching piezoelectric elements, such as crystal oscillators, filters, transformer cores, and timing circuits. This type of fixed inductor is also used to generate pulse applications, improve DC linearity, and as voltage regulator components. The 2020R-28H can also be used as a high current transformer for low voltage applications with low current flow.

Working Principle

The 2020R-28H is a fixed inductor, which means that when an electrical current passes through its wire element, it creates a magnetic field that stores energy. The strength of the magnetic field is determined by the number of turns in the wire element, the diameter of the wire, and the amount of insulation used. The higher the inductance of the device, the higher the stored energy will be. The 2020R-28H has an inductance of between 1 and 10 Henries, depending on the number of turns of the wire element and the type of core used.

The 2020R-28H also has a high current capacity with a maximum of 5.6A. This indicates that the wire element must be tightly wound to create a strong field with a high voltage tolerance. When a current is passed through the wire element, the magnetic field generated by the inductance creates a back-EMF, or a counter-electromotive force, that decreases the current flowing through the wire element. This is a crucial factor in allowing the 2020R-28H to be used as a high-current transformer in low-voltage applications with a low current flow.

Advantages

The 2020R-28H has several advantages when compared to other types of inductors, such as having a high current capacity and a low power consumption. The ability to generate a strong magnetic field with a high inductance also allows the 2020R-28H to be used for pulse applications with a high current rating. Finally, the 2020R-28H also has a high tolerance to voltage changes, making it well-suited for use in applications that require a large amount of voltage stability.

Conclusion

The 2020R-28H is a type of fixed inductor that is most often used in applications requiring a current rating up to an ampere value. It is designed for use in constant frequency applications and is capable of generating a strong magnetic field with a high inductance. The 2020R-28H also has a high current capacity and a low power consumption, along with a high tolerance to voltage changes. These features make the 2020R-28H ideal for applications such as crystal oscillators, filters, transformer cores, and timing circuits.
