Fixed inductors play a significant role in industry such as electronics. The RL110-121K series of fixed inductors are highly sought after in the market. It offers a wide range of features and benefits that make it a popular choice. This article will provide an overview of the application field and working principle of the RL110-121K series.

Features of the RL110-121K Series

The RL110-121K series of fixed inductors offers up to 10 different inductance values. It also features a voltage rating of up to 50VDC and a rated current of up to 2.6A. The series also offers a high frequency rate, up to 250MHz, and an over temperature protection range from -20°C to 110°C. Moreover, the series has a high radiative performance, as well as superior temperature coefficient of inductance (TCL).

Application Field

The RL110-121K series of fixed inductors are mainly used in the field of audio semiconductors, such as power amplifiers, speaker protection circuits, multimedia cards, FM/AM tuners, and other audio devices. It is also used in other applications where a high frequency rate is desired, such as in digital filters, LED power boosting circuit, flyback and step-up circuit, switching regulator, and over current protective circuit, among others.

Working Principle

The working principle behind the RL110-121K series of fixed inductors is based on electromagnetic induction and Faraday’s law of induction, which gives rise to the relation between an electric current and a magnetic field that surrounds it. The inductor is a two-terminal electronic component with a coil of wire and a magnetic core. When the current passes through the coil, it creates a magnetic field. This magnetic field induces a secondary current in the opposite direction, resulting in a recycling of energy. This is what is known as the inductor’s self-induction mechanism.

The RL110-121K series of fixed inductors offer superior performance due to the combination of the self-induction mechanism and a high frequency rate. The device is also equipped with an over-temperature protection range to prevent the overheating of the device. This ensures the long-term performance and reliability of the device.

Conclusion

The RL110-121K fixed inductor series is an excellent choice for a wide range of audio semiconductor and other applications. It features a wide range of inductance values, a high frequency rate, over-temperature protection, and superior temperature coefficient of inductance. It is a highly reliable device for various applications due to its solid construction and superior performance.
