SPM5020T-3R3M-CA

The Fixed Inductor is a vital component of many electrical and electronic systems. Within this category of components, the SPM5020T-3R3M-CA stands out as an application-specific component designed to serve a specific purpose.

SPM5020T-3R3M-CA is a type of fixed inductor manufactured by Sunpower Technology Corporation that is used in electrical and electronic circuits to store electrical energy in the form of a magnetic field. It is a non-polarized type of inductor consisting of a coil of copper wire with a solid core, although it can also be produced with an air core. This type of inductor has a nominal inductance rating of 3.3 mH and a current rating of 2.2 Amps. The SPM5020T-3R3M-CA also has a maximum DC resistance of 0.25 ohms, a temperature coefficient of -220 ppm/C, a turn ratio of 1:1, and a saturation current of 2.5 amps.

The primary application of the SPM5020T-3R3M-CA is in power supply circuits and filters. In a power supply circuit, this type of inductor is used to reduce electrical noise caused by voltage ripple. To do this, the inductor acts as a low pass filter and blocks high frequency components from passing through the circuit while allowing the low frequency components to pass through. This type of inductor can also be used as a choke in an AC circuit, where it acts to reduce the amplitude of the AC waveform, thus creating a smoothing effect on the signal passing through it.

The working principle of the SPM5020T-3R3M-CA is based on the concept of mutual inductance. This is the phenomenon of two coils of wire of the same inductance and current rating influencing each other’s magnetic fields. The resulting effect is that the inductance of one coil directs energy to the second coil and vice versa. This phenomenon is exploited in the SPM5020T-3R3M-CA to regulate current flow and filter electrical noise in circuits.

In summary, the SPM5020T-3R3M-CA is a type of fixed inductor manufactured by Sunpower Technology Corporation for use in power supply circuits and filters. It is primarily used to reduce voltage ripple noise and act as a choke in AC circuits. The working principle of this type of inductor revolves around the concept of mutual inductance.
