Fixed inductors are inductors that are designed to produce a fixed inductance for a given number of turns. They are widely used in many electrical and electronic circuits, from audio equipment to digital circuitry. The 103R-123HS inductor is an example of a fixed inductor that is specifically designed for use in high-frequency applications. This article will provide an overview of the application field and working principle of the 103R-123HS fixed inductor.

Application Field

The 103R-123HS fixed inductor is a surface mount component that is specifically designed for high-frequency applications. It is designed for use in DC-DC converters and isolated DC-DC converters up to 20KHz, making it ideal for a wide range of applications, including signals from mobile phones, GSM base stations, amplifiers and more. It is also used in switching DC-DC converters for medical and industrial applications. It is also suitable for applications with higher switching frequencies, up to 200KHz.

The 103R-123HS inductor is also designed to provide high temperature operation up to 200°C, making it suitable for use in very harsh industrial environments. It is rated to withstand up to 500mW of power, and can also handle up to 10A of current. It has a very low profile, making it suitable for use in space-constrained environments. As a result, it is widely used in communication systems, power supplies, audio equipment and more.

Working Principle

The 103R-123HS inductor works on the principle of inductance. In a component such as this, the inductance is created by creating a magnetic field with a wound coil of wire. This coil is made of an insulated copper material, which is then wound into a specific configuration. This winding design determines the inductance of the inductor. The 103R-123HS inductor is designed with a specific winding pattern, which gives it the high frequency operation for which it is designed.

The 103R-123HS inductor is also designed with an attrition layer to protect the inductance over time. This attrition layer protects the inductance from wear and tear due to vibrations and shocks. The attrition layer also protects the component from corrosion, resulting in a long life span.

The 103R-123HS inductor also includes a pre-set frequency stability feature, which ensures that it maintains its stated operating frequency throughout its lifetime. This is necessary for use in high-frequency applications, such as DC-DC converters and isolated DC-DC converters. It also helps to ensure that the inductor maintains its operating frequency even if the input voltage or current changes.

The 103R-123HS inductor is also designed with a low core loss, which helps to reduce power consumption in the circuit. This helps to reduce the overall cost of the circuit, as well as improve its efficiency.

The 103R-123HS inductor is a high-quality and reliable component that is designed for use in high-frequency applications. It is designed with a very low profile, making it suitable for use in space-constrained environments. It is also designed with a pre-set frequency stability feature and an attrition layer, which ensures that it maintains its stated operating frequency throughout its lifetime. As a result, it is widely used in communication systems, power supplies, audio equipment and more.
