Fixed inductors are passive components consisting of a coil of wire and a core, which provide a known resistance to an electrical current. The SDS850R-393M from Bourns is a device from the family of fixed inductors, specifically developed to provide reliable and efficient electrical current regulation in a wide range of applications. This fixed inductor offers excellent thermal stability, high-temperature endurance, low cost and high efficiency – all in a compact design.

The SDS850R-393M is a low-profile, surface-mountable device which is designed to provide a known, consistent resistance to current in a wide range of applications. Its main use is in power supply applications, where the fixed inductor is used to regulate the flow of current in order to ensure a stable voltage level. This device can also be used in order to efficiently convert nonlinear alternating current signals to linear direct current signals in power management systems, ensuring that the power supplied to a circuit stays within acceptable levels.

The working principle of the SDS850R-393M is based on Faraday\'s Law of induction. This states that when a magnetic field is changed through time, a current will be induced in a circuit. The fixed inductor works on this principle in order to provide a known resistance to current in a circuit. The core of the device consists of a tightly wound coil of wire, which creates a magnetic field when current is passed through it. As the current passes through the coil, a magnetic field is generated which applies a reverse, or “back-emf” voltage to the current, which opposes the movement of charge. This back-emf voltage, when combined with the direct current flowing through the device, results in the desired amount of resistance in the circuit.

The SDS850R-393M is one of the most popular devices from the family of fixed inductors, and is used in a wide range of applications. Its high efficiency, low cost, and compact design make it an ideal choice for power supply applications, as well as electrical current regulation and conversion. The device is also resistant to high temperatures, ensuring reliability and durability in long-term commercial and industrial applications.
