Fixed inductors are a type of passive component used in electronic circuits. They are used to provide a constant or variable electric signal to a circuit and are available in various sizes and shapes to suit the needs of different applications. SDR0503-391KL is a type of fixed inductor, specifically designed for aerospace applications.

The working principle of SDR0503-391KL is based on the use of an electromagnetic field to induce current in its windings. The current in the windings of the inductor produces a magnetic field which interacts with the adjacent magnetic field of the environment and induces a voltage. This voltage is proportional to the external magnetic field strength and the inductance of the inductor. For an inductor with a given size and winding structure, the inductance is determined by the number of turns in the winding. By changing the number of turns, the inductance of the inductor can be altered.

SDR0503-391KL is well-suited for applications that require high stability and high performance in low frequency signals, such as in RF applications, aerospace and satellite communication. The inductor has a standard tolerance of 1%, and an inductance range from 10uH to 390uH. It has a superior temperature coefficient, with a low temperature coefficient of -10,000ppm/°C, which makes it ideal for applications that require temperature stability. This inductor also has a high shielding capability and is ideal for high frequency applications, as it can effectively filter out the noise.

SDR0503-391KL is also an excellent choice for power management applications. It has a wide operating temperature range from -55°C to +125°C, and can easily handle peak currents of up to 20A. It is also RoHS compliant. Due to its high thermal capabilities, this inductor is highly suitable for power circuits, where it can store and transfer energy efficiently.

SDR0503-391KL is a reliable, high performance fixed inductor that is suitable for a variety of applications. Its high inductance range, excellent temperature stability, low temperature coefficient, and high power handling capabilities make it an ideal choice for many different types of projects. Additionally, its RoHS compliance makes it an attractive option for users in need of an environmentally friendly solution.
