Fixed Inductors are passive components that consist of a coil of wire with several turns that link with two opposite sides, which store energy temporarily in the form of a magnetic field when a current is passed through the wire. The 2890R-39G is one of the most popular types of Fixed Inductors, and its application and working principles are worth exploring in greater detail.

The 2890R-39G is a fixed inductor device that utilizes a ceramic core material and is enclosed in a molded plastic cover. It has a typical inductance range of 13.4 to 600 μH with a 3 A, 4 A, 5 A or 10 A rated current. Additionally, it has relatively low DC resistance and tolerates high temperature applications that make it suitable for various power electronic devices.

The primary application of the 2890R-39G is in power electronic circuits such as motor drivers, DC-DC converters, Pulse Width Modulation (PWM) converters and DC-AC inverters. It is typically used as a major part of regulating the current in these systems as its inductance works as a filter to the power devices. Additionally, the device\'s self-heating feature makes it applicable in resonant converters.

The working principle of the 2890R-39G is based on the magnetic field created when a current runs through the device. According to Lenz\'s Law, the induced current created by the passing current creates an opposing magnetic field that limits the current in the device, resulting in its inductance. This makes the 2890R-39G an ideal device for power electronics applications as it is capable of filtering and controlling the current even when subjected to high temperature applications.

Moreover, the 2890R-39G also has a wide range of operating temperatures, and can resist temperatures up to 125℃, which makes it suitable for a variety of heat related scenarios. Additionally, the device is also highly reliable, as it is capable of operating continuously for a long period of time without any significant degradation in performance.

Overall, the 2890R-39G is a highly versatile and reliable Inductor that has several applications in power electronics. Its low resistance and high temperature tolerance make it well suited for various current filtering and regulation tasks. Additionally, its low cost and long-term reliability make it an ideal component for any electronic device.
