Fixed Inductors

An inductor, also known as a coil, is an electrical component that stores energy in a magnetic field when electric current flows through it. A Fixed Inductor is a type of inductor that can be manufactured with precise inductance values, which are soldered or connected to PCBs in order to form a circuit. There are many types of Fixed Inductors used for different applications, such as power lines, loudspeakers, radio transmission, and signal filtering. The most common type is the SMD (surface mounted device) inductor, which consists of a core with windings located underneath. The SMD inductor is commonly found in electronic circuits, and has the advantage of being able to be used in limited spaces because of its compact size. The application field of Fixed Inductors is varied. They are commonly used in power supplies, voltage regulators, switching power supplies, and mobile device chargers. Fixed Inductors also play an important role in RF (radio frequency) applications, such as antennas and filters. Additionally, they are used in power amplifiers, energy storage, and speaker engineering.

Working Principle of Fixed Inductors

The working principle of Fixed Inductors is based on the principle of electromagnetic induction. When an electric current flows through a wire, a magnetic field is created around the wire. If the current changes, then the magnetic field will also change, which will induce a voltage in the wire due to Faraday’s law of induction. The induced voltage is proportional to the rate of change of the current.

The inductance of an inductor is related to the amount of magnetic field created and the amount of voltage induced. When the current increases, the magnetic field increases, and the voltage induced increases. When the current decreases, the magnetic field decreases, and the voltage induced decreases. The Fixed Inductors have a fixed inductance value that does not change with the current.

The Fixed Inductors are used to limit the current flow in a circuit, which can protect components from over-current. They are also used in radio transmitters, which require a stable current flow over time in order to successfully transmit a signal. Additionally, Fixed Inductors are used in filters to reduce the amount of noise in a signal.

Conclusion

Fixed Inductors are a type of inductor that can be manufactured with precise inductance values. Their application field includes power supplies, voltage regulators, switching power supplies, mobile device chargers, RF applications, power amplifiers, energy storage, and speaker engineering. The working principle of a Fixed Inductor is based on the principle of electromagnetic induction, and it is used to limit the current flow in a circuit, and also in radio transmitters and filters.
