Fixed inductors, such as LAL04SK471K, are typically used in applications where inductance needs to be maintained over a range of frequencies. This type of inductor is available in a variety of sizes and shapes and can be either or axial or radial lead type. It is commonly used in filter circuits, pulse transformers, switching power supplies, and other high-frequency applications.

The LAL04SK471K is an axial lead type inductor with a wide range of inductance values. It is rated at 0.4uH to 4.7uH and has a DC resistance range of 0.04 ohms to 0.4 ohms. It also has a temperature tolerance of +/- 5% and a temperature coefficient of 0.1mH/deg C or better. It is capable of handling up to 3 Watts of power and can operate over a temperature range of -55C to +105C Celsius.

The working principle behind a fixed inductor is based on the fact that current produces magnetic fields, and a changing magnetic field can induce an electromotive force in a conductor as described by Faraday’s Law. This is also known as electromagnetic induction. Basically, when an electrical current passes through a coil of wire, a magnetic field is created around the coil. This magnetic field then induces an electric current in any nearby wires in proportion to the change in magnetic flux. This electric current can then be used to maintain a steady magnetic field in the coil and thus sustain the desired inductance.

The LAL04SK471K is a good choice for applications that require a broad range of inductance values and need to be capable of dissipating up to 3 Watts of power. It also has relatively low DC resistance values and temperature tolerances. This fixed inductor can be used in a variety of applications such as filter circuits, pulse transformers, switching power supplies, and other high-frequency applications.
