Fixed Inductors

LK10051R2K-TV application fields and working principles are primarily related to fixed inductors. Fixed inductors, also referred to as "chokes," are used to limit the flow of AC electrical current, as well as limit interference from external electrical sources. By understanding the working principles of these devices, it is possible to determine the most suitable application field for their use.

Working Principle of Fixed Inductors

The working principle of fixed inductors is based on an electromagnet. When an electrical current is passed through the inductor\'s coil, it creates a magnetic field. This magnetic field stores energy in the form of magnetic flux and tends to keep the electrical current flowing in the same direction. This stored energy acts as an opposing force, reducing the amplitude of electrical current that flows through the inductor.

When the inductor is connected to an alternating current (AC) power source, the direction of the current in the inductor is constantly reversed. This reversals cause the magnetic field in the inductor to fluctuate, resulting in the alternating current being reduced to a smaller direct current (DC). This process of converting alternating current to direct current is referred to as AC/DC conversion, and is commonly used in power supplies and amplifiers.

Common Applications of LK10051R2K-TV

The LK10051R2K-TV fixed inductor can be used in a variety of applications. Its low profile makes it ideal for use in surface-mounted electronic devices, such as cell phones and tablets. Its maximum rated current of 5.2 amps makes it suitable for use in a range of power supply applications, such as LED lighting and medical devices. In addition, its high inductance and low DC resistance make it ideal for use in filters and low-frequency power conversion systems.

The inductor can also be used in EMI/RFI filter applications, such as appliances and consumer electronics. Its low resistance allows it to act as a shield against interference, while its high inductance limits the amplitude of current passing through it. This makes the LK10051R2K-TV an ideal choice for suppressing EMI/RFI noise in sensitive electronic devices.

Conclusion

The electromagnetic principles of fixed inductors make them suitable for a wide range of applications. The LK10051R2K-TV fixed inductor is a radial type, surface-mount device with an inductance of 100µH and a maximum current rating of 5.2 amps. It is suitable for use in low power devices, such as cell phones and tablets, as well as in power supplies, filters, LED lighting, medical devices, and EMI/RFI filter applications. By understanding the working principles of inductors, engineers can more effectively select the most suitable device for their application.
