Fixed inductors, or non-variable inductors, are passive components used in many electrical and electronic applications. The HLQ021R8BTTR is a surface mount fixed inductor used in a variety of low-frequency circuits. It has several features that make it an excellent choice for switching power supplies, DC-to-DC converters, and on-board power supplies. This article will discuss the application field and working principle of the HLQ021R8BTTR.

Applications
The HLQ021R8BTTR is a low-profile, fixed inductor that is designed to provide stable current filtering and voltage regulation in high current circuit designs. It is suitable for switching power supplies, DC-to-DC converters, and on-board power supplies. It is also suitable for use in general-purpose low-frequency electric circuits. The unique configuration of the inductor allows it to provide good filtering and voltage regulation in wide-variable current conditions.

Principle of Operation
The HLQ021R8BTTR is an inductor, a passive electrical component used to store energy in a magnetic field. Its fixed form is made up of a wire core made of a material such as ferrite or iron, wrapped in a coil of wire. When a current passes through the inductor, it generates a magnetic field. The magnitude of this field depends on the amount of current passing through the inductor. As the current passing through the inductor changes, the magnetic field also changes, thus inducing a voltage in the inductor. This voltage is then used to control the current through the inductor, providing voltage regulation and filtering.

The inductance value of the HLQ021R8BTTR (in µH) is marked on the label along with its peak current value (in A). The inductance value determines how strongly the magnetic field is generated and how much voltage is induced during operation, which in turn determines the current regulation of the inductor. The peak current value determines the maximum current that can be passed through the inductor without damaging it.

Conclusion
The HLQ021R8BTTR is a low-profile, fixed inductor that is suitable for use in low-frequency applications. It offers excellent current filtering and voltage regulation capabilities in wide-variable current conditions. The inductor’s peak current and inductance values can be found on its label, and these values determine the current regulation and maximum current, respectively. The HLQ021R8BTTR is an excellent choice for switching power supplies, DC-to-DC converters, and other low-frequency circuits.
