Fixed Inductors: 2150-38F Application Field and Working PrincipleFixed inductors, such as the 2150-38F, are devices that store and transfer electrical energy. They are used in any electronic circuit where precise, reliable voltage regulation is required. This field of application includes anything from power supplies, to audio or video equipment, to computers, to telecommunications systems.To understand how fixed inductors work, it is necessary to understand how current and voltage are related. Voltage is the difference in electrical potential between two points in a circuit. Current is the movement of electric charge through the circuit, and is measured in amperes (A). The relationship between voltage and current is described by Ohm\'s law, which states that voltage divided by current is equivalent to an electrical resistance.As electrical energy moves through a circuit, some of it is lost to heat or other forms of energy. In order to maintain a steady voltage and current, this energy must be regularly replenished. This is where fixed inductors come in. Fixed inductors use the principle of electromagnetic induction to generate a magnetic field that induces a voltage in the winding inside the inductor. This induced voltage in turn both stores and replenishes the lost energy, allowing the circuit to remain stable.The basic components of a fixed inductor, like the 2150-38F, are an iron core, a winding, and a coil. The core is made of steel and ferrite and is surrounded by the winding. Around this winding is an electrical coil, which is wound around the core to create a magnetic field. When a current flows through the circuit, the winding in the inductor stores energy, creating a magnetic field.When the voltage in the circuit drops, the stored energy in the winding acts to replenish the energy losses. This is referred to as "self-inductance" and is a basic principle of fixed inductors. The magnitude of the induced voltage is directly proportional to the rate of change of the current in the circuit. This means that the response of the inductor to voltage changes is very fast, allowing very precise regulation of voltage and current in the circuit.Fixed inductors are widely used in many electronic circuits, providing essential stability and reliability. The 2150-38F, for example, is a fixed inductor designed for use in audio equipment and consumer electronics. Its inductance is 0.0039H, and its maximum dissipation power is 0.75W. Its inductance is stable over the temperature range of -10 to +85°C, making it an ideal choice for use in even the most demanding applications.In summary, fixed inductors such as the 2150-38F are electrical components that store and transfer electrical energy. They use the principle of electromagnetic induction to generate a magnetic field that induces a voltage in the winding inside the inductor. This voltage helps to maintain a steady voltage and current level in the circuit. Fixed inductors are widely used in many electronic circuits, providing essential stability and reliability.
