Fixed InductorsFixed inductors are essential components in electronic circuits, primarily used for the purpose of storing energy in a magnetic field, such as providing a direct current (DC) path for electric flow, blocking direct current (DC) and allowing alternating current (AC) to pass, or providing passive filtering, to reduce energy transmission or improve signal quality. The 0819R-42K fixed inductor is widely used in a range of applications.The 0819R-42K is a cylindrical inductor with a screw-top terminal and leads that fit securely into a board. The inductor’s core is made of a high-permeability ferromagnetic material that provides good inductance and high efficiency. This type of inductor is popular because it is compact, lightweight, yet provides excellent performance.The working principle of this device is based on Faraday’s law which states that when a magnetic field passes through a winding of wires, it creates an induced current. This induced current creates an opposing magnetic field and the total magnetic flux increases as the current is increased. This increasing magnetic flux induces a voltage into the winding of the inductor, which limits the rate of current increase and is called inductive reactance. The inductance of an inductor is the opposition to an AC current and is quantified as the ratio of the induced voltage between the winding of the inductor to the current amplitude.The 0819R-42K inductor is widely used in automotive, aerospace, and telecommunications applications. It is mainly used in filtering and high-frequency circuitry, such as voltage regulators, power supplies, amplifiers, RF amplifiers, and other power electronics applications. It is also used as a low-dropout regulator, reducing power dissipation in power supplies. In addition, it can be used as a high-speed data coupling and bypass filter, as well as for signal conditioning and surge protection. The performance of the 0819R-42K fixed inductor is excellent, with high inductance over extended temperature ranges, low profile and low power dissipation in a wide range of operating conditions. It is also reliable and shock and vibration resistant. The inductor is available in a wide variety of form factors, including SMT, radial, and axial.The 0819R-42K is a high-quality fixed inductor that is used in a wide range of applications. Its features, performance, and reliability make it one of the most popular inductors on the market today. It is suitable for use in a wide variety of electronic circuits and systems, including automotive, aerospace, telecommunications, and industrial control.
