Fixed Inductors

Fixed inductors, also known as fixed-inductance devices, are electrical devices used to generate an electromagnetic field that induces a voltage in a workpiece. They consist of a coil of wire or some other conductive material, such as an air-core or ferrite core, and a core that provides mechanical support. When a current flows through the wire coil, a magnetic field is created, which in turn induces a voltage in the workpiece. Fixed inductors are used in a variety of electronic applications, such as radio receivers, power supplies, instrumentation, and audio systems.

744902112 Application Field and Working Principle

The 744902112 fixed inductor is a multi-layer structure integrated device. It has a wide range of applications in communication, consumer electronics, power supply, automotive electronics and other fields. Its working principle is basically the same as that of other fixed inductors. When an alternating current is applied, a time-varying magnetic field generates an electromotive force (emf) in the same coil. The magnitude and direction of this induced emf are related to the magnitude and direction of the current applied and the winding structure of the coil. The 744902112 uses a multi-layer winding structure, making it more efficient and having better performance in radiation resistance and other aspects.

The 744902112 fixed inductor is mainly used to store energy, create filter circuits, and increase current in high-frequency circuits such as radio communication equipment and other consumer electronics. Since the 744902112 has a high Q (quality factor), it is widely used in power supply circuits in the LM series used in mobile phones, PDAs, stereo components, and other electronic equipment.

Overall, the 744902112 fixed inductor is a popular choice for communications, consumer electronics, and power supply applications due to its relatively small size, high stability, and strong anti-radiation interference. In addition, it is also used in automotive electronics, railway high-speed networks, audio equipment, aerospace components, and other areas.
