Fixed Inductors

In today’s world, electronic components allow us to create ever more complex and powerful systems. Fixed inductors, or sometimes referred to as inductor coils, are one such component. The CF322513-120K is a one such fixed inductor, with a range of specific applications.

Description

The CF322513-120K is a type of surface mounted, portable inductor. It is built from a metal can like housing with 2, 2.5, or 6 lead pins. The terminals are soldered onto a printed circuit board. Inside, it contains a ferrite core, wrapped in a conductive wire. The wire can be most types of metal including, alumanim, copper, iron,selenium or silver. When referring to inductors, its specification is usually based upon its inductance, a measure of the component’s ability to store electrical energy. Here, it has a specificty of 1200nH (nano-Henry). This specific model is manufactured with a tolerance range of +-10%, meaning that it will keep to its specificty within a defined range. It also has a rated current of 0.53A (Amps) and a DC resistance of 0.45 ohms.

Applications

The CF322513-120K is used in a variety of industries for a range of different applications. It is commonly used in power supplies, as it’s able to smoothen out electrical current and can be used to filter noise. It is also suitable in low-frequency applications such as boosting or braking of electrical motors, and can also be used as radiation-resistant environmental monitoring.In modern technology such as in cars, it is used to help stabilise the electrical current flow and create a ‘low reactance pathway for alternating current’. Being relatively small and light, it is ideal for use in portable devices, such as laptops and and smartphones, in which energy conservation is important.

Working Principle

An inductor is a passive two-terminal electrical component that stores energy in its magnetic field. It works by creating an electrical current when exposed to a change in the magnetic field. simply, when a current flows through the wire, a magnetic field is produced around it. This generates the energy that is and transferred and stored.The CF322513-120K works according to Farady’s law, in which the electromotive force generated within it is proportional to the rate of change of the current flowing through it. Thus, it works to smooth out changes in the current flow, and upon exposing it to a sudden current change, it will compensate with an opposing force to prevent erratic behaviour.In essence, it is used to perform a range of processes that require preferential current flow or specific voltage values. As its core is wrapped in a wire, when electricity enters the CF322513-120K, it generates a magnetic field through the core. This magnetic field creates a force in the wire, which in turn, creates a changing electromotive force, resulting in induced energy.

Conclusion

The CF322513-120K is a versatile fixed inductor with a range of specific applications. It is used to stabilise current flow in circuits, smoothen the flow of electrical current, filter noise and create a ‘low reactance pathway for alternating current’. It works according to Faraday’s law, creating a magnetic field when electricity enters it, which generates a force in the wire that creates a changing electromotive force, resulting in inductive energy.
