Fixed inductors, also called non-variable inductors, are a type of component found in electronic circuits. They are used in a variety of applications including filters, amplifiers, and power supplies. One particular type of fixed inductor, the 0819R-22H, is commonly used in high-quaIity audio circuits and other signal processing applications.

The 0819R-22H is a high-quality, low-inductance inductor. Its construction consists of an aluminum case with two layers of insulation, a base, and two gold-plated terminals. The inductor is wound with 18 to 22 gauge enameled copper wire and has a self-resonant frequency of 24kHz to 40kHz. Its maximum DC current rating is 1.5A with an inductance of 4.2mH - 5mH.

The 0819R-22H is primarily used in audio amplification, signal processing, and power supply circuits. In audio circuits it is often used as an input filter or for crossover applications. Due to its low-inductance characteristics, it can produce a very shallow roll-off in response to higher frequencies, allowing for smoother and more transparent sound reproduction. In signal processing applications, the 0819R-22H is often used as a high-quality lowpass filter.

The 0819R-22H is also used in power supply circuits. Its lower inductance characteristics make it well-suited for power supplies that have components which require a steady DC supply. As the inductor prevents large ripple current from flowing, it helps reduce undesirable noise in the power supply circuit. The 0819R-22H is also immune to temperature changes, which makes it an ideal choice for power supplies which operate in extreme temperatures.

The 0819R-22H operates on the principle of electromagnetic induction. An alternating current passing through the inductor\'s windings creates an electromagnetic field which induces a voltage in the winding. This voltage opposes the voltage which created it, effectively slowing down the current and limiting the amount of current that can pass through the inductor. This is known as inductance, which is measured in henries (H). The 0819R-22H has an inductance of 4.2mH to 5mH.

The 0819R-22H is a versatile and reliable component which can be used in a variety of applications. Its low-inductance characteristics make it particularly well-suited for audio and signal processing circuits, while its immunity to temperature changes makes it an ideal choice for use in power supply circuits. As this versatile component continues to be used in a variety of applications, it will no doubt remain a critical component in the world of electronics.
