Fixed inductors are electronic components that store electrical energy in a magnetic field. They are usually made up of a coil of wire wrapped around a magnetically permeable core. This core acts as a medium that can control the magnitude of the inductance. The 4590R series (R = radial) 474K application field and working principle are no exception to this rule.

4590R-474K is a type of fixed inductor with its main applications in power supplies or power transmitters, like radio frequency power amplifiers and local oscillators, and various other electronic circuits. It is a physically small inductor, similar in size to a transistor and ideal for low frequency switching power supplies. It is widely used in laptop computers, LCD TVs, lasers, and medical treatments.

This inductor offers high inductance in a small size and low resistance. It also features low to moderate DC bias characteristics, meaning the inductance value does not change significantly as DC passes through the core. The low profile (0.190" [4.83mm] maximum height) of the 4590R-474K makes it particularly suitable for applications where board space is limited. Additionally, it is a reliable and cost effective product with its operating temperature range of -55°C to +100°C.

The working principle of the 4590R-474K is based on the magnetic induction rule of electromagnetism, where a current passing through a wire produces a magnetic field. When the current passes through the core of the inductor, a large magnetic field is generated and causes the electrons on the wire to be attracted and repelled away from the core, creating an inductive effect. This effect is known as self-Inductance. The inductance value of the inductors is directly proportional to the number of turns of wire around the core, and determines the amount of electromagnetic energy stored.

In practice, the 4590R-474K is designed to handle large currents and present a low impedance, meaning that the voltage on the output is considerably lower than the voltage on the input. This feature of the 4590R-474K is widely used in power supplies and motors to reduce the amount of power wastage and the amount of energy used. It is also used in AC/DC converters to regulate the amount of current entering a device.

The 4590R-474K is a valuable part of any power circuit or system where it is important to regulate current and reduce power wastage. Its size, performance, and reliability make it a popular choice for electronic engineers and designers. It is also widely used in various medical treatments and in high-power audio amplifiers, where its high-inductance allows for higher output power. Its low profile also makes it convenient for applications requiring low profile components, and its low resistance makes it a great choice for applications that require low power consumption and a low noise environment.
