Fixed inductors, also known as inductors, are two-terminal passive electrical components that store energy in the form of a magnetic field. SDS850R-474M is one of the most popular fixed inductors, which is widely used in a wide range of applications.

The SDS850R-474M is a high-performance toroidal inductor from a manufacturer of leaded components. The inductor is designed to deliver high performance at both low and high frequencies, with a working frequency range from 10 Hz to 10 MHz. It has a very low DCR of only 0.4 ohms, a very low saturation current of 8.5 A, and a very high inductance of 4.7 mH. The size is also very small, with dimensions of just 9.5 mm x 8.5 mm. Additionally, the component has an insulated wire core and is very lightweight.

The SDS850R-474M is mainly used in DC/DC converters, switching power supplies, and voltage regulation applications. It is commonly used in single-ended and bridge-mode power converters, because of its high performance, low saturation current, and small size. The component is also ideal for wideband noise suppression, impedance matching, and general DC filtering.

The working principle of the SDS850R-474M is based on Faraday\'s law of electromagnetic induction. When electric current flows through the component, a magnetic field is produced, which induces an electric voltage in the device. This voltage is inversely proportional to the rate of change of the magnetic field, i.e. the rate of change of the electric current. This voltage is used to regulate the current flow. Additionally, the component has a small self-resonance frequency, which can be used to reduce high-frequency noise.

In summary, the SDS850R-474M is a high-performance toroidal inductor from a manufacturer of leaded components. It has a very low DCR of only 0.4 ohms, a low saturation current of 8.5 A, and an inductance of 4.7 mH. The component is mainly used in DC/DC converters, switching power supplies, and voltage regulation applications. Its working principle is based on Faraday\'s law of electromagnetic induction, and it can be used for wideband noise suppression, impedance matching, and general DC filtering.
