Fixed inductors are components that store energy in the form of a magnetic field when electric current flows through them. The IRF01ST680K is a type of fixed inductor produced by Infineon Technologies AG, a global semiconductor manufacturer. It is a molded, surface-mount, high-current rated inductor with an impressive rated current of 16A-6.8uH.

The IRF01ST680K has an operating temperature range between -55°C and +155°C, making it suitable for use in harsh industrial and automotive high-temperature environments. The package size is a compact 9.6mm x 8.4mm, reducing the footprint of the inductor in the PCB layout. The design also features a solder-resistant SMD pad on the underside which enables secure mounting of the inductor.

The IRF01ST680K can be used in applications such as power supplies, frequency converters, motor drives, and DC-DC converters. It is also used in battery charging circuits, DC-rectified supply regulated power circuits, and PFC circuits. Additionally, it can be used as an output inductor in the switching mode power supply, because of its wide operating temperature range and its low-noise profile.

The working principle of the IRF01ST680K is based on the properties of an inductor, which is an electrical component that opposes changes in current. An inductor consists of a coil of wire wrapped around a ferromagnetic core. When electric current passes through the wire, it creates a magnetic field within the core. This magnetic field stores energy, and the energy is released in the form of an opposing current when the original current is removed.

The inductance of the IRF01ST680K is 6.8uH and its rated current is as high as 16A. The inductor features a low-noise inductance profile, allowing for precise inductance measurement at high frequencies. It also has a high saturation current of 17A, which ensures a high current handling capability in high-current applications.

The high current rating and low-noise profile of the IRF01ST680K make it an ideal choice for a wide range of power supply, frequency converter, motor drive, DC-DC converter, battery charging and power supply regulated circuits. Its inductive properties make it well-suited for use in high-temperature environments, and its compact size and solder-resistant SMD pad make it easy to assemble on a PCB. This makes it an ideal choice for integrated circuits and other space-constrained applications.
