Fixed inductors are among the most common linear components used in electronics circuits. They are used to induce a set amount of current or voltage in a circuit and provide a stable inductance value across a wide range of frequencies, from low-frequency signals through high-frequency signals. In this article, we’ll discuss the application field and working principle of the LQH32DN100K53L, a fixed inductor.

Application field: The LQH32DN100K53L is designed specifically for high-frequency applications, such as RF amplifier and antenna circuits, as well as various power supplies and more. The high self-resonant frequency (SRF) of 101 MHz makes it ideal for these applications, enabling it to achieve up to 7.6 dB of guaranteed impedance bandwidth for an operating frequency range of 1–300 MHz. This fixed inductor also exhibits excellent temperature stability and low ESR values, making it suitable for filter circuits and high-current applicaitions.

Working Principle: A fixed inductor is a component that uses its magnetic storage property to oppose electrical current. It is composed of a coil of winding wire with an air gap in the center. The electrical energy passing through the coil generates a magnetic field, and the inductor stores the energy until the current stops flowing. This is known as inductive reactance and is measured in Ohms.

The LQH32DN100K53L uses this reactance to reduce the amplitude of AC signals, which is known as impedance matching. The inductor can also be used as an inductive filter, preventing certain frequencies from passing through. This enables it to be used for EMI noise suppression, and it can also be used for impedance stabilization to prevent damage to the signal due to signal distortion.

Additionally, the LQH32DN100K53L can be used to generate an inductive load, allowing designers to create low-power circuits. This can be used to create a bridge rectifier circuit, which uses alternating current to power a circuit that functions as both an rectifier and an inductor. This kind of circuit is used in many devices such as solar panels, automotive systems, and many other applications.

Overall, the versatile nature of the LQH32DN100K53L makes it an ideal choice for a variety of high-frequency applications. It provides excellent temperature stability, low ESR values, a high SRF, and a wide impedance bandwidth. Its ability to act as an inductive load or filter make it a very powerful component for a range of different applications.
