Fixed Inductors

Inductors are passive electronic components used to store electric energy in the form of magnetic energy. They are widely used in many electronic circuits and applications due to their relatively simple construction and low cost. The physical structure and properties of an inductor are based on Faraday\'s Law of Induction, which states that an electric current flowing through a conductor creates a magnetic field around it. Therefore, by winding a wire in a certain pattern, an inductor can be created. A fixed inductor is an inductor that is manufactured with a specific inductance value. The PT12121SL Inductor is a fixed inductor with a 12.1 mH inductance, a 20% tolerance, a maximum current of 9.98A, and a maximum DC resistance of 0.126 Ω.

PT12121SL application field and working principle

The PT12121SL Inductor is a fixed inductor designed for use in a wide range of electronic circuits and systems. It is commonly used in power supplies, power converters, and switch-mode power supplies (SMPS). In addition, this inductor is used in many communication systems, such as telecommunication systems, automotive systems, and industrial systems. Furthermore, the inductor can also be used for filtering applications and other non-power applications.

The PT12121SL inductor works on the principle of Faraday\'s Law of Induction. According to this law, when an electric current passes through a conductor, a magnetic field is created around it. This magnetic field, in turn, induces a voltage in the form of an EMF (electro-motive force) in the inductor. The inductor resists the flow of current and stores energy in the magnetic field. The magnitude of the induced EMF is proportional to the rate of change of the current. As the current through the inductor changes, the EMF also changes, causing the inductor to oppose the current flow, thus providing impedance to the circuit.

The PT12121SL Inductor is designed to be used in a wide range of applications. Its 12.1 mH inductance and 20% tolerance make it an ideal choice for use in power supplies, power converters, switch-mode power supplies, automotive systems, telecommunication systems, industrial systems, and other filtering and non-power applications. This inductor also has a maximum current rating of up to 9.98A and a maximum DC resistance of 0.126Ω.
