Fixed inductors are components used in electrical circuits and in a wide range of applications where inductance is needed or required. They come in a variety of sizes and shapes and provide a variety of functions. In particular, the ER1025-44KR is a popular choice due to its high quality. This type of inductor is often used for switching, power supply protection, and other applications.

The ER1025-44KR is a horizontally-mounted, surface-mount inductor with a magnetically shielded construction. Its size is typically 0.38" (9.7mm) by 0.36" (9mm) for most sizes and it provides and inductance range of 0.3 to 15uH at a current range of 0.1 to 10A. It also features a high rated current up to 17A and an ability to operate up to 100 mΩ, thanks to its low DCR (DC resistance).

This type of inductor is ideal for a variety of applications. It is especially useful in filtering high-frequency, high-power applications, such as automotive and industrial power supplies. With its high current, it can effectively absorb high surge current, which can be a problem for other inductors. It can also be used for common-mode choke applications, such as limiting high-frequency noise that might cause interference.

The working principle of the ER1025-44KR is fairly straightforward. When a current is placed through the inductor coil, a magnetic field is created. This magnetic field then reacts with the inductor core, causing it to store energy. This stored energy then produces a resistive force, which opposes the current in the coil and reduces the current’s rate of flow. The amount of this resistive force depends on the inductance of the coil, which can be adjusted by changing the coil\'s shape or size.

In addition to its applications mentioned above, the ER1025-44KR can also be used as a RF choke, a transducer for convert parameters such as a temperature, or a low pass filter for power supplies. It is often used in space-constrained applications such as smartphones or computers, as its size gives it a certain level of versatility. Thanks to its many uses, the ER1025-44KR is an extremely popular choice for a wide variety of applications.
