Fixed inductors are passive electronic components that are used to store energy in the form of magnetic fields. They can be found in many applications due to their wide range of electrical characteristics, from high frequency to low voltage operation. The 105R-221HS is a type of fixed inductor specifically used for DC-DC converters, high frequency filters, switching regulation circuits, and motor control circuits.

General Specifications

The general specifications of the 105R-221HS provide detailed information on the electrical characteristics of this type of fixed inductor. It has a rated inductance of 0.36mH, and rated current of 0.5 Amps. It also has a saturation current of 1.2 Amps and saturation flux of 0.065 Wb (Wb stands for Webers). The temperature coefficient of inductance is -0.11dB/deg C, and the self-resonant frequency is 12MHz. Additionally, its core material is ferrite and its configuration is toroidal. In terms of shape, the 105R-221HS is almost circular with a total diameter of 8.2mm and a body height of 5.7mm.

Application Field

The 105R-221HS is mainly used for DC-DC Converters and other applications that require a high frequency filter or switching regulation circuits such as motor control circuits. These inductors are particularly useful for switching increase and step-down voltages, as they can reduce the amount of current being drawn, thereby reducing energy usage. In addition, they are often used in switching power supply applications, as they can reduce the ripple voltage and current significantly. Furthermore, they are highly efficient and can handle large current loads.

Working Principle

The working principle of the 105R-221HS is based on an electromagnetic field. When a current flows through the inductor, a magnetic field is generated that generates a voltage across its terminals. This is known as Faraday\'s Law, which states that the voltage induced is directly proportional to the rate of change of the current through it. Due to this, inductors can store and release energy in the form of a magnetic field, making them a key component of many electrical circuits.

Conclusion

In conclusion, the 105R-221HS is a type of fixed inductor that is mainly used for applications that involve high-frequency filters, switching regulation circuits, and motor control circuits. It has a rated inductance of 0.36mH, a rated current of 0.5 Amps, and a temperature coefficient of inductance of -0.11dB/deg C. The working principle behind this type of inductor is Faraday\'s Law, which states that a voltage is induced across its terminals when a current is passed through it. As such, they can store and release energy efficiently in the form of a magnetic field.
