PT12133SJL Application Field and Working Principle

PT12133SJL is a fixed inductor which is a device used in electronic circuits. It stores energy in the form of magnetic field and releases the energy when required. PT12133SJL is mainly used to increase or decrease the current through a circuit. The inductors can also be used to filter out unwanted signals, control impedance and prevent high frequency signals from passing through. PT12133SJL can also block the passage of DC current.

In terms of application field, PT12133SJL find its wide range of uses in various electronic products, such as personal digital assistant (PDA), air-conditioner, PC monitor, switching power supplies, medical electronics and consumer electronics. It plays a major role in the circuit to maintain accuracy of the signal, while also having good performance in power loss.

The working principle of a fixed inductor will be best described using Faraday’s law. As a current passes through an inductor, the amount of magnetic flux is proportional to the amount of current. The magnetic field induces an EMF, or induced voltage, in the inductor at this ratio. With the right amount of current, the right amount of magnetic flux is produced in the inductor.

This magnetic flux will, in turn, induce another current in the inductor. It flows in the opposite direction of the induced current, and as such, it is called the back-emf. The back-emf will reach its maximum value when the current reaches its maximum value. The back-emf opposes the applied voltage, which results in a decrease in the amount of current flowing in the circuit. Thus, an inductor can act as a way to limit current.

PT12133SJL is constructed using a high-quality ferrite core, which ensures high inductance and low heat generation. It also features a shrink tube, which ensures reliable connection and long lasting insulation. The inductance of PT12133SJL is guaranteed in the range of 10~220mH. Its temperature stability is -55℃~+125℃, and its direct current is 0.25A. With all these specifications, this component opens up a wide range of application for different industries.

In conclusion, PT12133SJL is a fixed inductor which finds wide range of uses in various electronic products. It operates on the principle of Faraday’s law, whereby the magnetic flux produced induces a back-emf to limit the amount of current. This component has good temperature stability and direct current, made possible through its ferrite core and shrink tube. PT12133SJL is therefore a reliable component that any electronics engineer should take into consideration when making their designs.
