Fixed inductors are an indispensable part of electronic engineering and are used in many applications, such as signal filtration, sensing, and coupling. The 1638R-00J is an example of a fixed inductor that has a wide range of applications and a simple working principle.

One of the most common applications of the 1638R-00J is to filter electromagnetic interference (EMI) on a PCB. An inductor works by providing electrical resistance within a certain frequency range, so the inductor is connected between the uncontrolled, noisy signal and the controlled, desired signal to block some of the frequencies. The 1638R-00J is able to accomplish this task due to its low DC resistance and wide operating range.

In addition to signal filtration, the 1638R-00J is also used in DC-DC converters and current sensing applications. In DC-DC converters, it is often used to create a “flyback” voltage in order to increase the voltage levels and provide a stable output. As for current sensing, the inductor is used to measure current by creating a small magnetic field around the winding of the inductor. This magnetic field alters the inductance of the winding, which in turn allows the inductance to be measured.

The working principle behind the 1638R-00J is relatively simple. A basic two-terminal inductor consists of two wire coils, separated by a small amount of air, or other insulation material. When a current is applied to the two coils, a magnetic field is created between the two coils, which in turn creates inductance. This is due to the fact that the field will oppose the applied current, since current wants to travel in a circular path, rather than straight.

The 1638R-00J is a relatively low-cost inductor, designed to operate at low frequencies. The inductance of the device is 15 µH and the rated DC current is 20mA. The device also has a power rating of 1 watt, and an ac amplitude current rating of 200mA. It has a low DC resistance of 11 ohms, which makes it ideal for applications such as signal filtration.

The 1638R-00J is a simple yet effective fixed inductor, which can be used in a wide range of applications. Due to its low cost and wide range of features, the 1638R-00J has become a popular choice for many electronic engineers. It is capable of providing effective signal filtration, DC-DC conversion, and current sensing, making it one of the most versatile fixed inductors available.
