Fixed inductors are important components in the electronic industry, and 103R-102J is a type of these devices. Fixed inductors have been widely used in various types of electronic equipment, including filter, power supply, signal processing, switching, communications and other applications. This paper aims to discuss the application field and working principle of 103R-102J.

103R-102J is an inductive reactance device with very wide frequency range. It can be used in filter, power supply, signal processing, switching, communications and other circuits. In fact, they are commonly used to control current flow os through AC or DC power supplies, sense signals or form low- and high-pass filters. 103R-102J has two terminals, one of which is composed of a ferrite core and an inductor coil. The other terminal is connected to either a DC voltage, AC voltage or an analog signal.

In general, the working principle of fixed inductors is pretty simple. When a current resides through the inductor, a magnetic field will be generated in the core, thus making impedance to the current flow. The amount of impedance is equal to the inductance of the inductor. The impedance is also affected by the frequency of the current. The higher the frequency, the higher the impedance. The amount of inductance of 103R-102J is usually preset to certain value, typically between several hundred to several thousand microhenries.

In terms of application fields, 103R-102J is often used in various electronic circuits with different needs. Firstly, they are widely used as low pass filters due to their wide frequency range and large inductance. For example, a low pass filter composed of 103R-102J can be used to filter out noise frequencies from an audio signal. Secondly, they can be used in a power supply, as they can be used to control the current flow and prevent overloading. In addition, 103R-102J can be used as signal processing devices, such as signal mixers or oscillators. Finally, they can also be used as radio frequency filter, which is commonly used in communication and switching applications.

In conclusion, 103R-102J is a type of fixed inductors that have wide frequency range and large inductance. It is commonly used in filter, power supply, signal processing, switching, communications and other applications. The basic working principle behind 103R-102J is that when a current passes through the inductor, a magnetic field will be generated and cause impedance to the current flow. Therefore, it is one of the most important components in the electronic industry and its application field keeps expanding due to its various advantages.
