4445-21K

Fixed inductors are single-coil components used primarily in electronic circuits for the purpose of performing functions such as filtering or transient suppression. The 4445-21K fixed inductor is a simple device that is used in a wide variety of applications, including power regulators, oscillators, switching requests and for normal inductor filtering. The 4445-21K fixed inductor is reliable and versatile, making it a popular choice for those looking to get the most out of their electronic circuit components.

The 4445-21K fixed inductor is made up of two main components. First, the spiraled wire core is wound up with copper wire, which is then wrapped in enamel insulation. Next, a two-way terminal is soldered to each end of the core, and the package is then sealed with a plastic housing. These two components form the main body of the inductor, and the current passing through will be regulated by the electromagnetic field created by the two terminals.

The 4445-21K fixed inductor is capable of operating from -55°C to 125°C, making them well-suited to both harsh environments and everyday use. With a rated current of up to 1.21A, as well as a maximum DC resistance of 0.14 ohms, the 4445-21K is able to handle significant power loads in many different applications. Furthermore, the package size of the 4445-21K fixed inductor is extremely small compared to other components, allowing it to be used in tight spaces without compromising performance.

The 4445-21K Fixed Inductor has a number of applications in both industrial and consumer electronics. The primary use of fixed inductors is to introduce inductance into an electrical circuit, which can help to provide filtering or transient suppression. This is useful for limiting the current which flows through a circuit, as well as controlling any additional power components. The 4445-21K can also be used to introduce inductance into a signal line to reduce EMI, as well as providing an additional form of filtering which helps reduce noise in audio circuits.

In addition, the 4445-21K Fixed Inductor has a number of other uses in various applications. It can be used as a voltage regulator, as an inductive choke for energy storage, as an oscillator, or as an automation device for motor control. Furthermore, the 4445-21K can also be used as a damping component in high-frequency switching applications, allowing engineers to reduce the amount of current switching noise that is generated from these circuits.

The 4445-21K Fixed Inductor is a highly versatile component, providing reliable performance in a broad range of applications. With an operating temperature range of -55°C to 125°C, this fixed inductor can handle large loads with ease. Furthermore, the size of the package allows the component to be used in space-restricted applications without sacrificing performance.
