Fixed inductors are components used to store electronic energy in an electromagnetic field. This energy is then released in the form of an electric current when the component is activated. DR1040-221-R is a type of fixed inductor used for a variety of applications.The DR1040-221-R is a shielded inductor with a cylindrical body and four lead wire connections. Its electrical properties make it suitable for a variety of broad applications, including RF filter inductors, DC-DC converters, motor drive circuits, and switching power supplies. The inductor is also designed for resonance and high-frequency applications, as well as for use in switch-mode power supplies, charge pumps, and switching regulators.The DR1040-221-R is constructed with two windings of wire. The core material is composed of a metallic substrate and a dielectric coating. This combination creates an electromagnetic field when a current passes through the windings. The dielectric coating increases the inductor’s energy storage capacity, allowing it to handle larger currents without saturation.DC inductance and inductive reactance of the DR1040-221-R are usually around 2 mH and 38 ohms respectively, depending on the application and size of the inductor. The DC current rating of the inductor is 4A, and the rated DC resistance is 0.7 ohms. The maximum operating frequency of this inductor is 1 MHz and its temperature range is 0°C to 70°C.The working principle of the DR1040-221-R inductor is based on Faraday’s law of induction. This law states that when the number of coils in a winding changes, an electromotive force is produced. The current induces an electromagnetic field in the inductor core, which then stores energy in the form of magnetic flux. When the current is removed, the stored energy is dissipated as a current through the inductor’s winding.The DR1040-221-R is a versatile fixed inductor, ideal for controlling current and voltage in a variety of electronic circuits. Its shielded construction and high power capacity make it suitable for applications ranging from computer to consumer electronics. The DR1040-221-R is a reliable and cost efficient choice for both professional and hobbyist users.
