Fixed Inductors: 103-820K Application Field and Working Principle

Developed in the late 19th century, fixed inductors are components used for storing and controlling electrical current in a device. While they can be mechanical, manual, or off-the-shelf, they typically are passive components in the form of coils. According to Ohm’s Law, a fixed inductor in a circuit causes a voltage drop proportional to the current passing through it. In this way, fixed inductors impact the flow of electrical current throughout a device, making them essential for device operation.

The 103-820K fixed inductor is a good example of a fixed inductor. Unlike mechanical and manual inductors, these are off-the-shelf components specifically designed for high-frequency applications. The model number indicates the range of the inductor, with 103 representing a range of 10nH to 820nH. The inductor also has an operating frequency of 250MHz to 900MHz.

In addition to these technical characteristics, the 103-820K inductor has six primary elements that make it useful for a variety of applications. The first is a "Coil", a length of wire wrapped around a "Core" in order to generate a magnetic field. This magnetic field affects the flow of electrical current. The core is usually made out of metal or ferrite, and it serves to focus the magnetic field generated by the coil. The core also helps to reduce losses in the system.

The second element is a "Terminal", which is used to attach the inductor to a circuit board. Typically, electrical current is passed through the terminal, which then goes on to the Coil and Core. The last element is a "Package", which is a casing meant to protect the inductor and stabilize its operation. The package also keeps the inductor in place in a circuit board and has a nominal inductance value inscribed on it.

A 103-820K fixed inductor is ideal for high frequency applications, mainly because of its high operating frequency range of 250MHz to 900MHz. This range is well suited for applications such as amplifiers, RF transmission, microwave circuits, and air filters. Additionally, the high frequency allows for more efficient operation for these applications without consuming too much power.

The 103-820K fixed inductor works by forming a closed loop with the Coil and Core. When an electrical current passes through the terminal, the Coil creates a magnetic field which is focused and amplified by the Core. This magnetic field then interacts with the electrical current, causing it to flow in a circular motion, thus forming a closed loop. This loop produces a voltage drop proportional to the current passing through it, which can be used to control the flow of electrical current.

The 103-820K fixed inductor proves to be a useful technology for high frequency applications. Through its six elements, such as the coil, core, and package, it efficiently applies the principles of Ohm’s Law to generate a voltage drop proportional to the current passing through it. Additionally, its broad operating frequency range allows it to be used in many different applications such as amplifiers and air filters. With this high-tech component, engineers are able to control electrical current in a more efficient and reliable manner.
