Fixed inductors refer to a type of passive component that consists primarily of a coil of insulated metal wire wound around a core. The most common type is a magnetically-coupled inductor, which consists of two coils; one with fewer turns of wire than the other, usually referred to as a primary winding or a primary coil, and the second with more turns of wire, usually referred to as a secondary winding or a secondary coil. The 8230-74 application field and working principle of these components can be divided into three main categories.

1. Power Supply or Voltage Regulation: Inductors are used as part of a power supply or voltage regulator circuit to provide a storage device for electrical energy. The inductor stores the energy in the form of a magnetic field and then releases it as needed. When current flows through an inductor\'s primary winding, it generates a magnetic field. The magnetic field then induces a current in the secondary winding, providing the output voltage needed to power a device.

2. Filter Circuits: These components are used in filter circuits to block high-frequency signals while allowing low-frequency signals to pass. For example, filter circuits are used in radio receivers to tune in to specific frequencies. The inductor helps to filter out unwanted signals by blocking the higher-frequency signals and allowing only the desired frequency to pass through.

3. Oscillator Circuits: Inductors are used in oscillator circuits to produce AC signals for use in radios and other devices. The inductor is connected to a capacitor, and the combination of the two produces an oscillating voltage. This voltage fluctuates in a specific frequency and can be used to control the frequency of an oscillator circuit.

The 8230-74 application field and working principle of a fixed inductor depend on its specific design but typically include filtering, power supply regulation, and oscillator circuit applications. In each case, the inductor helps to regulate, filter, or create a specific signal necessary for the device being used.
