Fixed inductors are passive electrical components used in electronic circuits to store electrical energy in the form of a magnetic field. The magnetic field produced by the inductor can be used to induce a voltage or provide resistance to current flow. The LHL16TB471K is a type of fixed inductor commonly used in electronic circuits due to its small form factor, reliable performance and ease of use. Its applications include decoupling and filtering circuits, power supplies, and audio circuits.

The LHL16TB471K fixed inductor is a surface mounted device (SMD) that measures 1.6 mm x 1.2 mm x 0.72 mm. It features an inductance of 0.47 µH and an operating temperature range of -55°C to +125°C. It is rated at 100 mA with a maximum DC resistance of 20 mΩ and a Q factor of 7. This makes it ideal for decoupling medium-frequency ripple from signals in high-speed digital circuits.

The working principle of a fixed inductor is based on Faraday\'s Law of Induction. Faraday\'s Law states that when a conductor is exposed to a changing magnetic field, an induced current will flow in that conductor. Fixed inductors rely on this concept, using a coil of wire to create a magnetic field when current passes through it. When the current is removed, the magnetic field of the coil collapses, and a voltage is generated in the conductor proportional to the rate at which the field collapsed. The voltage induced in the conductor is opposed by a reactance that is based on the inductance of the coil. The inductance is measured in Henries, also known as ohm-seconds (Ωs).

Fixed inductors are widely used in electronic circuits due to their low cost and ease of use. They are commonly used for decoupling, filtering, and audio signal conditioning. The LHL16TB471K is a popular fixed inductor because of its small size, high performance, and wide operating temperature range. Thanks to its 100 mA current rating and low resistance, it is suitable for a wide range of applications up to medium frequencies, including power supplies and audio circuits.
