PL9307 Datasheet/PDFFixed Inductors
A fixed inductor is an inductor whose inductance value is fixed, with the windings of its coils arranged in a specific pattern to attain the inductance value. The most common type of fixed inductor is the PL9307, which is a convenient way to add inductance to electronic circuits. It is widely used in a range of devices, such as amplifiers, radio transmitters, receivers, and signal processing circuits.
Application Field
Fixed inductors are commonly used in electronic components and systems that require inductance. This includes power supplies, radio receivers, and antenna circuits. In these applications, the inductor can reduce interference from other signals or provide a preferred signaling path. It is also used in amplifiers, signal conditioners, power supplies, and other circuits that require inductance. Fixed inductors can also be used to filter high-frequency signals, reduce noise, and provide power conditioning for sensitive circuits.
Working Principle
The working principle of a fixed inductor is based on Faraday’s law of induction. This law states that when a current is passed through a conductor, it produces a magnetic field around the conductor. This field induces voltage in the neighboring conductors through the principle of electromagnetic induction. A fixed inductor works by creating an induced electric current in a closed circuit. The induced current passes through the inductor’s coil, creating a magnetic field that increases as the current increases. When the current reaches its maximum, the magnetic field stops increasing and the inductor reduces the current. This helps reduce interference in the circuit, allowing it to operate as intended.
Fixed inductors are widely used in many types of electronics. They offer a convenient and reliable way to modify or regulate current flow in a circuit, helping to reduce interference and create a desired signal path. The PL9307 is a popular choice for many electronics applications, making it an essential part of any electronics toolkit.
