Fixed Inductors

Fixed inductors are electronic components which are made up of coils of wire insulated by special materials, allowing them to build up a magnetic field when current is passed through them. They are most commonly used for the filtering of DC current and for the creation of resistance circuits, providing an alternating current or a signal of some sort. The RLB9012-333KL is an example of a fixed inductor, and its application and working principle can be broken down into three key components.

Structure

The RLB9012-333KL is made up of two sets of coils. The first is a single layer of windings, which contains 170 windings of various sizes. This layer is connected to the second layer, which is composed of approximately 250 windings of the same size. This combination allows the inductor to have a maximum capacity of 333KL.

Applications

The RLB9012-333KL is most commonly used for the filtering of DC current and for the creation of resistance circuits, providing an alternating current or a signal of some sort. This type of inductor is also often used in the manufacture of electronic components, such as radio frequency circuits, power supplies and motor control circuits.

Working Principle

When a current is applied to the RLB9012-333KL, it will create a magnetic field, which creates a counter-electromagnetic force, or EMF. This EMF will oppose the flow of the current, eventually reducing it to zero, in a process known as ‘self-induction’. This is what makes inductors so effective in the filtering of DC current.In conclusion, the RLB9012-333KL is a type of fixed inductor which is used in the filtering of DC current and for the creation of resistance circuits, providing an alternating current or a signal of some sort. Its structure consists of two layers of variously sized windings, and its working principle is based on self-induction, whereby the EMF created by the inductor opposes the flow of the current, reducing it to zero.
