Fixed Inductors

Fixed inductors are circuits which play an important role in a wide range of devices. These include radio transmitters and receivers, amplifiers, television sets, and other communication equipment. The LB3218T100K is one such fixed inductor, designed for use in various digital control applications.

LB3218T100K Application Field and Working Principle

LB3218T100K is a medium-sized fixed inductor with excellent heat dissipation capability. It is mainly used in digital control circuits and low-frequency circuits, such as for high-integrity current sensors, high-efficiency control motors, and system safety monitoring circuits with high reliability. The inductor features a high-frequency switching performance and is suitable for various electronic components. It can be used in LED drivers, buzzing noise circuits, and temperature compensation circuits.

The working principle of the LB3218T100K is based on Faraday\'s law. This law states that the voltage induced in a circuit is proportional to the rate of change of the magnetic flux passing through the circuit. Whenever there is a change in the current passing through the coil, an opposing voltage is induced in the coil, maintaining a constant magnetic flux, and the current is effectively limited.

The LB3218T100K has an inductance of 100uH. This means that any current passing through the coil has to include a delay time, since current passing through an inductor produces a magnetic field that reacts with the coil\'s current, creating an opposing voltage. This ensures that the current is limited, making it ideal for use in digital control applications.

The LB3218T100K also has a core material of high temperature thermoplastic, copper and tin plated copper wire, which ensures stable performance. This increases the stability and durability of the inductor and reduces the risks of electromagnetic interference. The maximum working temperature of LB3218T100K is 105 degrees Celsius, making it suitable for most operating environments.

The LB3218T100K can also be used for pulse circuits. This is due to its ability to hold low current for an extended period. As such, it can be used in high frequency, wide bandwidth pulse circuits, increasing its applicability for various types of digital applications.

In summary, the LB3218T100K fixed inductor is a versatile and reliable component, able to provide reliable operation in a variety of digital control applications. It features a high-frequency switching performance, high operational temperature, low current pulse holding, and excellent heat dissipation capability. Its reliable operation makes it an ideal choice for digital control systems.
