Fixed inductors, also known as coils, are electronic components used in circuits to contain and store energy in the form of a magnetic field. They work by passing a current through a coil of wire, creating a magnetic field around the wire, and thereby causing an inductance, or buildup, of energy. The 4922-42L is a fixed inductor that is built with axial leads, making it suitable for most types of applications.

The 4922-42L has an inductance of 2.2 μH, a resistance of 0.199 ohms, and a tolerance of 5%. The maximum current rating for the inductor is 1.25A, and the maximum voltage rating is 1KV. The temperature coefficient is +- 10%, making it suitable for use in temperature-sensitive applications. The inductor also has a high self-resonant frequency of 800MHz, making it suitable for high-frequency applications.

The 4922-42L is commonly used in applications such as RF filters, oscillators, transformers, power supply filters, and motor drive circuits. As a two-wire component, it is ideal for use in AC-DC and DC-DC applications. The inductor is also used in high-end systems where its low electrical noise and temperature coefficient provides greater temperature stability and efficiency. In addition, the inductor can be used in precision circuits, such as precision timers, clocks, level detectors, voltage converters, and voltage regulators.

The working principle of the 4922-42L is based on Lenz’s law, which states that an induced current in a circuit will always oppose the original source of current. The Lenz’s law takes effect when a current is passed through a wire. The current in the wire will create a magnetic field around it, and this magnetic field will oppose the source of the current. This opposition is known as inductance or damping, and it is this effect which allows the 4922-42L inductor to filter out high-frequency noise and prevent the buildup of heat.

The 4922-42L has a range of features that make it suitable for a variety of applications, from RF filters to power supply filters, and from level detectors to voltage converters. It is an effective component for controlling current flow, providing a stable and efficient operating environment, and it is also highly reliable and durable. With its axial lead construction, the 4922-42L is simple and easy to use, making it an ideal choice for a wide range of applications.
