4922-39H

Fixed inductors are widely used in a variety of fields, including telecom, dimmers, switching power supplies and logic circuits. These inductors are used to store electrical energy and create a magnetic field. The type 4922-39H is a fixed inductor that comes with a self-heating temperature compensation technology that increases its life. It also has an epoxy sealed body, which makes it very suitable for use in harsh environments.

The 4922-39H has a good performance over a wide temperature range, which is suitable for use in extreme temperatures. It has a thermal compensation coefficient of 0.820/°C, and can withstand temperatures up to 185°F (85°C). Furthermore, the inductor is designed with a high frequency capability, so that it can handle signals up to 3 GHz. The device also works with various inductance values, ranging from 0.1 uH to 100 uH, and has a high insulation resistance of more than 5 GΩ.

The 4922-39H operates on the principle of electromagnetic induction. It has a two-wire connection and a core that can be composed of ferrite or iron. When a DC voltage is applied across the leads, a current flow is created within the core, generating a magnetic field around the inductor. This magnetic field stores the energy, and blocks the flow of AC currents. When the current flows, the inductor opposes the current, thus inducing a counter-voltage around the inductor. In this way, the 4922-39H helps in stabilizing the voltage and avoiding oscillations or changing variations.

Due to its stable performance and operation under extreme temperatures, the 4922-39H fixed inductor is used in various applications, such as RF amplifiers, switching supplies, inverters, and motor controllers. It is also commonly used in automotive systems, for ignition timing and in dimmers for controlling the flow of electricity. The inductor is designed to be highly reliable, and has a minimum linear power rating of up to 4 watts. Additionally, it has a lower starting current and can operate at extremely low frequencies.

The 4922-39H fixed inductor is a useful device for controlling electrical signals and the flow of current in various applications. It operates on the principle of electromagnetic induction, where a current flow through the core creates a magnetic field. This field then stores energy and blocks the flow of AC currents. Furthermore, the device is designed to withstand extreme temperatures and is highly reliable in various applications.
