Fixed Inductors

Fixed inductors, also known as fixed coils, are electronic components designed to store energy in the form of a magnetic field. They are generally made up of a core material such as ferrite or iron-dust sandwiched between two conducting plates, which are typically copper. They are usually wrapped with insulated wire coils, which act as the primary coil. When current is passed through the primary coil, it produces a magnetic field which stores energy and inducts voltage into the secondary coil.The LAL04SK331K is a Fixed Inductor that is most commonly used in power-conversion circuits, especially in applications that require high-inductance. This type of inductor is suitable for commercial operating frequencies of up to 1MHz. The LAL04SK331K has an inductance of 330nH, a high current of 49 A and a saturation current of 58.5 A.The LAL04SK331K works in the same way as other inductors by converting electrical energy into magnetic energy. When current is applied to the coil, it stores energy as a magnetic field. This energy is then converted back into electrical energy, inducing a voltage in the secondary coil. This voltage can be used to power other circuits or components.The LAL04SK331K’s main application field is in AC to DC power converters. Its high-inductance and high saturation current allow the inductor to provide efficient and reliable power conversion for circuits with high peak current. The LAL04SK331K is also suitable for applications in other high-power circuits such as automotive and LED lighting, mobile phones, laptop adapters and even household appliances.The LAL04SK331K is also a popular choice for switching converters, such as buck, boost, flyback, and forward converters. It can also be used in winding transformers and motor-starting applications for its high-inductance and high saturation current. In conclusion, the LAL04SK331K is an inductor specifically designed for power conversion projects due to its high-inductance, high saturation current, and low DC wind resistance. It is suitable for use in a wide range of applications from AC to DC power converters, automotive, LED lighting, and even motor-starting. The LAL04SK331K is a reliable and efficient inductor that is widely used in fixed inductor circuits.
