Fixed inductors are electrical components that are designed to induce a certain amount of current, usually alternating current. They are commonly found in circuits and are used in a variety of applications ranging from consumer electronics to industrial applications.The 1638-20H is an extremely popular fixed inductor and is used in many different applications. It\'s able to provide reliable electromagnetic performance, as well as better power handling compared to other inductors. The main reasons people choose the 1638-20H for their applications are its simple installation process, its low cost, and its ability to accurately and efficiently regulate current.One of the most common applications for the 1638-20H is in motor control. An inductor works by having a coil wrapped around a permanent magnet. When current flows through the coil, the magnetic field created induces a voltage in the opposite direction, thus producing a current. This current can then be used to control a motor or other electrical device.The 1638-20H inductor is able to provide accurate control over a wide range of current. This is because the core material used in the 1638-20H is designed to be completely non-linear. This allows the inductor to provide efficient current levels without needing an excessive range of voltages.The 1638-20H is also effective for noise reduction. The inductance of an inductor is determined by the turns ratio of its winding, and the 1638-20H has a lower turns ratio than most standard inductors. This means that it is less likely to be disturbed by electronic noise. For applications where noise reduction is desired, the 1638-20H can be a great solution.In addition to noise reduction, the 1638-20H also provides better temperature stability. The core material is designed to have good thermal properties, meaning it will maintain its properties at a wide range of temperatures. This makes it ideal for applications such as rectifier, filters, and power supplies, where a stable inductance is needed.Finally, the 1638-20H is also very reliable. The core material has excellent dynamic properties, meaning it won\'t be prone to wear or degradation over time. The winding has also been designed to last for years, even in high current applications. This makes it a great choice for high reliability applications, such as automotive and medical electronics.Overall, the 1638-20H is an extremely versatile fixed inductor that is perfect for a wide range of applications. Its simple installation process, low cost, and reliable operation make it an ideal choice for many applications, including motor control, noise reduction, temperature stability, and reliability. With all these features, it\'s easy to see why the 1638-20H is a popular choice for many applications.
