Fixed Inductors

Fixed inductors are electrical components used to provide a controlled amount of inductance. They are available in many different types and sizes and can be used for a variety of applications. Fixed inductors are essential components in many electronic circuits and provide a vital function in a variety of applications in the modern world.

The SPM4012T-1R0M-CA is a fixed inductor specifically designed for power supply applications. It is an axial-leaded, high performance inductor. The inductor is composed of powder-coated nickel-zinc core with a tin-plated copper body and sleeve. This device has an inductance of 1µH, resistance of 0.0725ohms, and a distinct current rating of 1.4A.

The SPM4012T-1R0M-CA is highly suitable for use in switching power supply circuits. Its high current rating makes it a robust and reliable component in such circuits. It is also suitable for use in motor drives, audio amplifiers, and many other applications.

The working principle of the SPM4012T-1R0M-CA is based on the property of inductance. Inductance is the property of an electrical circuit that opposes the change of current in the circuit. It occurs when the current through a coil changes, and it can be thought of as the energy stored in the coil when an electric current passes through it. As the current increases, the magnetic field increases and the inductance increases. As the current decreases, the magnetic field decreases and the inductance decreases.

The magnetic field created by a current in a coil is proportional to the number of turns in the coil, the amount of current through the coil, and the magnetic field around it. The magnetic field also interacts with any neighboring magnetic fields, which can affect the inductance of the coil. Generally, the more turns in a coil, the more inductance it will have. However, the amount of inductance also depends on other factors including the diameter of the coil, the material the coil is made of, and its proximity to other nearby coils.

The SPM4012T-1R0M-CA is a reliable and robust fixed inductor that is suitable for use in switching power supply circuits due to its high current rating as well as its ability to withstand high temperatures. Its ability to efficiently store energy makes it an essential component in many electronic circuits and modern application.
