Fixed inductors refer to the simplest type of components with a relatively fixed inductance value in electronic circuits. In general, they are composed of magnetic cores and windings, and the shape of the core and the number and orientation of the windings determine the inductance value of the inductor. 103-273HS is a specific model of fixed inductor.

Application Field
The 103-273HS fixed inductor is mostly used in power electronics circuits and high-frequency circuits. It is mainly suitable for applications such as high-current filters, pulse transformers, voltage regulator modules, speed controllers, inverters and switching power supplies.

Working Principle
The working principle of the 103-273HS is similar to that of most fixed inductors. The magnetic field produced by the current flowing through its windings and the magnetic core will cause the inductance value of the inductor to increase. The 103-273HS has an inductance value of 147 nH, which is relatively stable and rarely changes with changes in the current or the frequency of the alternating current. It also has a low DC resistance of 0.04 ohms, which means that it can pass more electric current. The core and the winding material of the 103-273HS are selected carefully in order to achieve the best performance and also to reduce the thermal noise generated by the heat generated by the large current.

The 103-273HS is also provided with some additional features such as thermal protection and over-current protection. The thermal protection mechanism ensures that the inductor does not overheat if the current passing through the winding exceeds the rated current. The over-current protection mechanism disconnects the winding if the current passing through the winding exceeds the rated current, thus protecting the device from an excessive current.

In conclusion, the 103-273HS is a fixed inductor with an inductance value of 147 nH, a low DC resistance of 0.04 ohms, and has additional features such as thermal protection and over-current protection. It is mainly used in power electronics circuits and high-frequency circuits. The core and the winding material of the 103-273HS are selected carefully in order to achieve the best performance and also to reduce the thermal noise generated by the heat generated by the large current.
