Fixed inductors are electrical components that have the ability to store and release energy in the form of an electromagnetic field. For many electrical applications, a fixed inductor is an ideal choice. The LAL02VA1R2K fixed inductor is used in appliances, military applications, industrial controls, and other electrical applications. This article will explain the use cases for this inductor and its working principle.The LAL02VA1R2K is designed for applications that require high current, such as filters and power amplifiers. This inductor is rated at 2 watts and offers a low effective series resistance at 0.48 ohms. It is a surface-mounted device that offers a large variety of mounting options. Its construction also allows for high reliability and performance in extreme temperatures.The LAL02VA1R2K is capable of handling up to 33A of continuous current. This inductor is also very efficient, with a tan δ value of 0.03 and a Q factor of >100. The coil is wound with filter grade wire and consists of an outer shell for shielding from EMI and RFI.The working principle of a fixed inductor is similar to that of a transformer. A transformer converts one AC voltage to another based on a set of electric coils. Similarly, an inductor stores energy in an electric coil and then releases it in the form of a magnetic field. When current flows through the coil, a magnetic field is created around the coil. This magnetic field generates voltage, which is then stored in the form of an electric field.The field created by the coil is used to store the energy and to control the current flow. By controlling the current, the inductor can behave as an AC-DC converter or a frequency filter. In addition, the stored energy can be used to reduce the noise or ripple in power supplies.The LAL02VA1R2K offers a high-current, low-distortion solution for power supplies and other electrical applications. Its large variety of mounting options and its efficient construction make it an ideal choice for many applications. Its high current and high-Q factor make it a great choice for design applications such as filters and power amplifiers.
