Fixed Inductors are a type of electrical component consisting of a coil or loops of wire that, when an adherent is present, stores energy and produces a magnetic field. The inductor is commonly used to create a local voltage or current change in a circuit by inducing a small amount of energy into it, often when the circuit is powered down or disrupted. An example of a common type of fixed inductor is the SPM4015T-1R5M-CA, here we will discuss its application fields and working principle.

The SPM4015T-1R5M-CA is a high-performance, high-current fixed inductor designed for use in DC-DC conversion circuits. It has a wide range of rated current levels from 1A up to 6A and a wide temperature range from -25℃ to 125℃, meaning it can be used in many applications with various cooling requirements. Additionally, the inductor has a very low DC resistance of 0.018ohm, making it an ideal choice for high-current applications.

Common applications for the SPM4015T-1R5M-CA includes use in DC-DC converters, Li-ion battery charging circuits, power inverters, LED lighting modules, switched mode power supplies (SMPS), and audio amplifiers. The inductor is also often used in power supplies for computers, as it is highly resistant to thermal changes, allowing it to handle high currents. This makes it a great choice for applications that require a reliable and dependable electrical component.

The working principle of fixed inductors is fairly simple. When an electric current passes through the conductor, it creates a magnetic field which then induces a current into the adjacent parts of the circuit. This alternating current produced by the inductor is typically referred to as the “inductance”. As the inductance changes, so does the voltage or current in the circuit. This is the main function of the SPM4015T-1R5M-CA; to regulate voltage and current levels within a circuit.

In conclusion, the SPM4015T-1R5M-CA is a high-performance fixed inductor that is primarily used in DC-DC converters. It has a wide range of current levels and a high temperature range, making it ideal for many applications. The working principle of fixed inductors is to induce a current into the circuit, which can then be used to either increase or decrease the voltage or current in the circuit.
