Fixed Inductors

Inductors are a key element in electronic circuits, widely used in many areas. Fixed inductors, also known as fixed inductance components, can be divided into two categories: regular fixed inductors and precision fixed inductors. This article will introduce the application field and working principle of one model precision fixed inductors – RLB0912-821KL.

Application Field and Working Principle

RLB0912-821KL is a 1210 size precision winding ceramic core electronic components. Due to its low DC resistance, low temperature drift, low magnetic sensitivities and high reliability, it is mainly used in LCD related device and digital communication device.

The RLB0912-821KL precision winding ceramic core is made of high permeability ferrite core with a small gap. Inside it, a fine wire is wound around the core in multiple layers, leaving very little space between each layer in order to control the gap. The multiple turns of the fine wire, as well as the core, form the inductance of the inductor. The space between the windings is very small, so the distributions within the fine wire is regular. This results in a very small DC resistance, which is often used to calculate the value of the inductor.

Resistance and capacitance also play an important role in the working principle of the RLB0912-821KL precision winding ceramic core. The resistance is mainly the DC resistance of the fine wire, the capacitance is caused by the gap between the layers of winding and the ferrite core. When AC current passes through the inductor, these three components will interact with each other and form an inductor equivalent circuit. This equivalent circuit will generate reactance at a certain frequency, obstructing the flow of current and creating the inductance.

In summary, RLB0912-821KL is a precision winding ceramic core with great performance. With its low DC resistance, low temperature drift and low magnetic sensitivities, it is widely used in LCD related device and digital communication device.
