Fixed Inductors

Inductors, known as coils, chokes, or reactors, are passive two-terminal electrical components used to store energy in a magnetic field. Fixed Inductors are coils with a constant inductance, meaning no matter what current is flowing through them, they provide a fixed, unchanging inductance. An example of a fixed inductor is the B82144A2104J009.

The B82144A2104J009 is a 104-millihenry inductor featuring a wirewound construction and molded body. It has a high self-resonant frequency of up to 200 MHz and a low DC resistance of just 0.006 ohms. It also has a wide current range of up to 3 amperes and an operating temperature of -55 to +150 Celsius, making it suitable for use in a range of different applications.

The B82144A2104J009 is primarily used in power supply and radio frequency circuits. As an inductor, it stores energy in its magnetic field when a current flows through it. Its ability to store energy makes it useful for filtering DC signals in low and high-pass filters, and its high self-resonant frequency also makes it useful for high-frequency switching applications.

The B82144A2104J009 also plays an important role in power supplies, where it is used to help reduce hum created by EMI (electromagnetic interference) and other sources. To do this, it helps to filter out unwanted noise picked up by the power supply, while also regulating the supply voltage, ensuring that a stable output is produced.

The basic principle of operation for fixed inductors is based on Faraday\'s Law of Induction. According to this law, when a current is applied through an inductor, a magnetic field is created around the wire. This in turn induces an electromotive force (EMF), which opposes the current flow, creating a back EMF. The magnitude of this back EMF is proportional to the rate of change of the current, and ultimately this determines the inductance of the coil.

In summary, the B82144A2104J009 is a fixed inductor used primarily in power supplies and radio frequency circuits, where it helps filter out unwanted noise while also providing stable output voltages. It works on the principle of Faraday\'s Law of Induction, which states that when a current is applied through an inductor, a back EMF is created that is proportional to the rate of change of the current.
