Introduction

Fixed Inductors are components used in electronic circuits that resist the flow of current by magnetically storing energy. One such component is the NS12575T1R2NN, which is used for high-frequency applications. In order to properly understand how this specific inductor works it is important to explore its design, application field, and working principle.

Design

The NS12575T1R2NN is shaped like an elongated cylinder and measures 7.0 x 5.7 x 3.6 mm. It is wound from copper wire, with a 28 AWG core. The outer coating is aluminum and the top is a silicon material. The impedance of the inductor ranges between 0.9 to 3.5 Ohms. The operating temperature range of the inductor is between -40 to +85°C. It is rated to operate at peak currents of up to 4.5 Amps. Maximum power rated for the NS12575T1R2NN is 11.75 Watts.

Application Field

The NS12575T1R2NN is used in a variety of high-frequency applications, such as radio and telecommunications equipment, radar systems, and switching converters. It is also used in power supplies, motor drives, and antenna systems. It is suitable for high-speed circuit applications, as it can provide fast response for signals with high frequency.

Working Principle

The NS12575T1R2NN operates on the principle of inductance. The inductor resists the flow of current by magnetically storing energy. When current is passed through the body of the inductor, it produces a magnetic field that is proportional to the applied current. This magnetic field then creates an opposing electrical force to the current, which results in a decrease in energy travelling through the inductor. The NS12575T1R2NN also works on the principle of resistance. As current passes through the wire, it generates heat. This heat is dissipated through the body of the inductor, which means that the inductor will operate at a lower temperature. This helps increase the durability of the inductor.

Conclusion

The NS12575T1R2NN is a fixed inductor used in high-frequency applications. It operates on the principles of inductance and resistance, with the magnetic field created by current flow producing an opposing electrical force, thus reducing energy flow, while heat generated by wire resistance is dissipated through the body of the inductor. Its design includes an aluminum casing, a silicon top, and 28 AWG copper wire wound around a 7 x 5.7 x 3.6 mm body. The operating voltage range is -40 to +85 °C and the rated peak current is up to 4.5 Amps. The power rating is 11.75 W.
