Fixed inductors refer to components formed by winding a coil former in the forms of a cylinder, hexagon, rectangular box and so on, using magnetic wires such as copper wires or cobalt wires and then forming it into an inductor component. The main purpose of it is to store electromagnetic energy, filter signal or adjust current and impedance. SRU3028-330M is one of the fixed inductors.

SRU3028-330M, a radial inductor of 0805 body size, belongs to the SR series, designed with high current rated. It is an enhanced version of SRU3028 series, allows higher ripple current, lower ACR, lower DCR and bigger dimension. It has a dimension of 2mm x 1.25mm x 0.8mm and the tested inductance tolerance reaching to 10%.

The maximum current rating of SRU3028-330M is 2.2A. It is designed mainly for automotive and consumer electronics. As for the application field, it is mainly used in pulse and ripple filtering circuit, this part inductance is 330nH. Application of this product includes LCD TV, notebook PC, PDA, and wireless communication.

The working principle of SRU3028-330M also lies in the fixed inductor. When the current flows through the winding of the inductor, the magnetic field is produced. As a result, the inductor stores energy through the generated magnetic field. Thus it can store and release energy as current, thereby attaining the effect of anti-interference for the electronic components.

In addition, fixed inductors do not only provide inductance, but they also perform impedance transformation functions at certain frequencies. This is because of its unique frequency characteristic, which increase the resistance with the increase in frequency. Besides, when the inductor coils are wound in different numbers, different inductance values will be obtained.

Apart from being used in pulse and ripple filtering circuits, fixed inductors like SRU3028-330M can also be used in other applications. These include power lines, DC to DC converters, coil antenna, timer, clock circuits and so on. All these applications show the actual functioning of the inductors, and provide proof of how well they can enhance the performance and effectiveness of electronic components.

In conclusion, SRU3028-330M is a fixed inductor with 330nH inductance and 2.2A current rating. It is mainly for use in automobiles and consumer electronics, which provides inductance, anti-interference and impedance transformation functions during different frequency signals. Apart from being suitable for pulse and ripple filtering circuits, it can also be used in various other applications such as power lines, DC to DC converters, antenna and timer circuits, demonstrating its great potentials in the electronics industry.
