Fixed inductors are a type of electrical devices which have a specified range of inductance values. In the case of the 4590-126K, this particular device is an surface-mountable rectangular inductor, designed for applications requiring inductance values in the range of 0.33 mH to 10 mH. The device housing, which measures 6.3mm x 5.3mm in size, is molded in a glossy blue plastic material with a white top and four copper leads. The device is also RoHS compliant.

Fixed inductors like the 4590-126K are used in a variety of applications, typically those where inductance is an important parameter. Common uses include power supplies, electronic transformers, current limiters, timing circuits, as well as control and filter circuits. They are also used in automotive, industrial, medical, and military applications.

The basic operating principle of a fixed inductor is the same regardless of the specific device being used: an electrical current is passed through a coil of insulated copper wire, the resulting magnetic field induces a reaction in the wire, and a back voltage is generated. This back voltage can be used to perform various tasks, such as storing energy, limiting or shaping current flow, or controlling other circuit parameters. The amount of inductance is determined by the design of the coil, making inductors Voltage-controlled devices.

The 4590-126K is specifically designed for high-temperature applications, with an operating temperature range of -55 °C to +125 °C. The device also features various parameters designed to maximize reliability, such as the use of a glass-filled epoxy for the housing. The inductor also features a low-resonance frequency of 250 MHz, making it ideal for applications requiring high performance and high efficiency.

In conclusion, the 4590-126K is a high-temperature surface-mountable rectangular inductor, designed for applications where inductance is an important parameter. The device is RoHS compliant, featuring a low-resonance frequency and a temperature range of -55 °C to +125 °C. The inductor’s operation is based on the collective principles of electromagnetic induction, whereby a current passing through a coil generates a back voltage which is used to perform various tasks. This device is commonly used in power supplies, automotive, industrial, medical, and military applications, among others.
