Fixed inductors are electronic components which store electrical energy in a magnetic field. They are primarily used to filter signals, smooth voltage, and improve signal-to-noise ratio. The ELJ-QE3N9ZFA is a type of fixed inductor that is widely used in many applications, such as wireless communications, satellite navigation systems, and base station power supplies. In this article, we will discuss the application field and working principle of the ELJ-QE3N9ZFA.

The ELJ-QE3N9ZFA is a small size fixed inductor with excellent high-frequency characteristics, which makes it an ideal choice for various applications. It has an operation frequency range of 4 kHz to 10 GHz, high-accuracy inductance range of 4 nH to 10 mH, and ultra-low noise performance of − 68 dB. The ELJ-QE3N9ZFA is also equipped with a built-in temperature compensation circuit, which allows the device to maintain stable performance in temperatures ranging from 25°C to + 85°C.

The ELJ-QE3N9ZFA can be used for a variety of applications, including RF matching networks, RF filters, diplexers, and various high-frequency power circuits.

The ELJ-QE3N9ZFA is a reliable and cost-effective solution for many of these applications.

The working principle of the ELJ-QE3N9ZFA is based on the principle of inductance. Inductors are devices that store energy in the form of a magnetic field, which is created when a current is passed through the device. The inductor acts as a resistor, causing the current to decrease the closer it gets to the source. The size of the inductor can be adjusted to achieve different levels of inductance, which can be used to achieve specific performances, such as high-Q factor, stable frequency response, or low-noise performance. By adjusting the size of the inductance coil inside the ELJ-QE3N9ZFA, users can achieve their desired performance.

The ELJ-QE3N9ZFA is a widely used fixed inductor with excellent performance, making it a popular choice for many applications. Its low noise performance, high-accuracy inductance range, and built-in temperature compensation circuit make it an ideal choice for applications that require precision performances. Furthermore, its small size and cost-effectiveness also make it an attractive choice for many users.
