Fixed inductors are components or devices that are often used in electric, electronic, radio frequency and other kinds of circuits, and serve important roles in these circuits. Fixed inductors are designed to create a stable current or voltage in a circuit, using a steady magnetic field. The model number B82472G4222M000 itself illustrates the quality and use of fixed inductors.

The first two characters of the model number, B8, refer to the manufacturer, EPCOS Bourns Inc., a manufacturer of fixed inductors and other semiconductor devices. The following two digits, 24, denote the series number of the inductor. The 72 in the middle stands for the inductance value, which is expressed in nanohenries (nH). It is followed by the last two digits, G4, which refer to the tolerance of the inductance, in this case +120/-80 percent. The letter M represents the package or body size of the inductor, which in this instance is 0.2 inches.

A fixed inductor is a type of inductor with a fixed inductance, meaning it does not vary with the changes in current. This makes fixed inductors suitable for controlling the current flow in electric and electronic circuits, and for filtering high-frequency noise from the signal. The main purpose of a fixed inductor is to store a certain amount of energy in the form of a magnetic field, which it releases as required. This helps maintain the stability of the voltage or current in the circuit.

The working principle of fixed inductors can be explained in simple terms. When current flows through the inductor, the wires around the inductor core generate a magnetic field, which stores the energy in the form of an electro-magnetic field. This stored energy is released when the current drops, forming an electrical field in the inductor core. In essence, the current that flows through a fixed inductor is limited by the amount of energy stored in the field.

The B82472G4222M000 is a general purpose fixed inductor, suitable for a wide range of applications such as filters, oscillators, choke coils, transformers, amplifiers, audio circuits, power supplies, and control circuits. Due to its high inductance and stable operating characteristics, it is an ideal component for use in noise filtering and signal conditioning.

Fixed inductors are widely used in a wide range of industries and applications, from aerospace to consumer electronics. They offer superior performance, making them a dependable and reliable component for many years. The B82472G4222M000 is a great example of how fixed inductor technology has advanced over the years, offering superior performance and stability in a variety of applications.
