Fixed Inductors:

Fixed inductors are passive electronic components that store energy in the form of a magnetic field. They are widely used electrical components in electric circuits due to their ability to resist changes in current flow, voltage and temperature. The 0819R-36G is a type of fixed inductor that is particularly used in high frequency switching circuits and voltage regulation, amongst other applications. This article will discuss the application field and working principle of the 0819R-36G.

The 0819R-36G fixed inductor is a small size, high frequency surface mount device that is suited for a wide range of applications. It is able to carry up to one watt of power and has a ferrite core with an inductance of 100uH. The 0819R-36G can be used in the following applications:

• DC-DC Power Converters: The 0819R-36G can be used in DC-DC power converters to control and regulate output voltage and current. The inductance of the core helps to store energy which can be released quickly to maintain the desired output voltage and current.
• Switch Mode Power Supplies (SMPS): The 0819R-36G can also be used in switch mode power supplies. Its high frequency and small size makes it an ideal choice for this type of application. The inductance of the core helps to reduce electrical noise generated by the SMPS.
• Radio Frequency Circuits: The 0819R-36G is also suitable for use in radio frequency circuits. It can be used as a filter to pass wanted frequencies but to block out unwanted frequencies, allowing improved clarity of signals.
• Power Factor Correction: The 0819R-36G can also be used in power factor correction circuits. The core inductance helps to reduce power draw from the mains, improving efficiency and reducing electricity bills.

The 0819R-36G has a simple working principle, as with most fixed inductors. When current passes through the core, it sets up a magnetic field which stores energy. When the current is reduced or removed, this energy is released in the form of a back-EMF which induces a voltage and current in the opposite direction to the flow of current in the core. This helps to resist changes in current, voltage and temperature, which is the principle of most electrical components that use a fixed inductor.

In conclusion, the 0819R-36G fixed inductor is a versatile and highly useful device, suitable for a wide range of applications. It has a high frequency and small size, which allows it to be easily incorporated into a variety of circuit designs, from radio frequency circuits to power factor correction. Ultimately, it is the inductance of the core that makes the 0819R-36G fixed inductor an effective device for these applications, providing the resistive ability to changes in current, voltage and temperature.
