Fixed Inductors

An inductor can be simply described as a coil or winding of wire that produces a magnetic field when current is passed through it. This magnetic field can affect the way electrons in other components of a circuit behave. Fixed inductors are components designed to precisely control the inductance of a circuit. One of the most popular products in this category is the LK1608R68K-T.

LK1608R68K-T Application Field

The LK1608R68K-T is a compact and high-performance multi-layer ceramic power inductor. It is used in a wide range of automotive, consumer, and industrial applications. It also has strong corrosion resistance and low noise levels, making it ideal for any environment. This inductor can also handle temperatures up to 150°C without any degradation. It is typically used in switched-mode power supplies, DC/DC converters, and SMPS applications. Due to its small size, the inductor can also be used in mobile phones, digital cameras, and other small devices where space is limited.

LK1608R68K-T Working Principle

The LK1608R68K-T inductor works by creating a magnetic field when current flows through the inductor. This magnetic field stores energy in the form of a magnetic field. The magnetic field then causes the electrons in other components of the circuit to move in a particular pattern, limiting the current to a specific level.The main principle of operation for the inductor is that of the self-inductance. This means that when a current passes through the inductor, a self-induced back voltage is generated. This back voltage will oppose the current and the inductor will act as a resistor, limiting the current and providing the required inductance. The LK1608R68K-T inductor also has an additional feature called an “inrush current blocking function”, which prevents an overvoltage spike during the power on phase of the device.

Conclusion

The LK1608R68K-T fixed inductor is a highly efficient component that can be used in a multitude of applications. Its small size and high temperature tolerance make it suitable for use in a variety of devices, and its inrush current blocking function ensures that the device is protected against overvoltage during the power on phase. The main principle of operation for the inductor is that of the self-inductance, meaning it creates a back voltage that opposes the current, providing the required inductance.
