Fixed inductors are inductors that have a fixed geometry that cannot be altered. These inductors are used for a variety of electrical applications, and the 2890R-18K is one such example. This inductor is used in various applications, and this article will discuss the field of application and the working principle of the 2890R-18K.The 2890R-18K is a surface mounted, shielded, molded power inductor with a ferrite core. It has a high current capacity and can handle up to 14 amps of current. It has a wide range of application fields, including automotive electronics, consumer electronics, power supplies, and so on. In addition, the inductor is also suitable for high-frequency switching applications.The inductance of the 2890R-18K is 20µH ±10%. This is relatively high for an application like this, and it allows the inductor to be used in high-current, low-ripple operations. The inductor also has a low DC resistance of 5.3Ω and a high saturation current of 16.5A. Furthermore, the inductor is immune to magnetic interference, making it suitable for RF applications.Now let’s take a look at the working principle of the 2890R-18K. The inductor works by creating a magnetic field when current flows through it. The magnetic field induces a voltage across the inductor, which opposes the current. This helps to reduce the current in the circuit. Thus, the inductor acts as a voltage and current regulator and can be used to reduce the amount of ripple in the output of a power supply.The 2890R-18K is built to be robust and has good heat dissipation. This helps to extend its life and improve its performance. The inductor also has a wide operating temperature range (–40 to +125 °C), making it suitable for a variety of applications.The 2890R-18K is a versatile inductor that can be used for a wide range of applications. Its wide range of specifications and robust design make it an ideal choice for many applications. From automotive electronics to consumer electronics and power supplies, the 2890R-18K is suitable for a wide range of applications that require high current, low-ripple operations.
