Fixed Inductors

A fixed inductor, also known as an inductor, is a passive two-terminal electrical component amounting to a wire with a coil wrapped around it. It stores energy in the form of magnetic energy, which is why it is commonly referred to as an energy storage device. In more sophisticated systems, inductors interact with other inductors and capacitors to form LC networks, which can provide digital signal processing.

The LQW18AN52NG80D is a series of fixed inductors manufactured by Panasonic, targeting a variety of electronic applications. It is designed with a self-shield structure consisting of a hollow magnetic core and an external wire coil. This structure allows for improved inductance, higher saturation current, better temperature characteristics, higher Q factor, and low DC resistance. The LQW18AN52NG80D offers superior performance in terms of size, resistance, stability, and noise characteristics.

This series of fixed inductors are typically used in radio-frequency filter circuits, such as cellular base station filters, as well as antenna matching circuits, impedance matching, switching power supplies, analogue filters, and other types of electronic circuits. This series of inductors are designed with high frequency characteristics and low resistor value, making them suitable for high frequency applications.

The working principle of a fixed inductor is simple. When an electric current passes through the wire coil, it produces a magnetic field. This magnetic field interacts with the electric current in the form of inductance, resisting changes in the current. The inductance of the coil will then improve as the number of turns in the coil increases, which leads to improved performance of the inductor, and hence, better performance of the entire circuit.

The LQW18AN52NG80D offers excellent performance with its high self-shielding characteristics, as well as its low DC resistance. It is able to withstand high frequencies and temperatures, making it suitable for demanding applications. Its small size also allows it to be used in tight spaces. Moreover, its high Q-factor provides excellent noise immunity, allowing for a more reliable operation.

In conclusion, the LQW18AN52NG50D series of fixed inductors offer improved performance compared to other types of inductors. It is suitable for a variety of applications, including radio-frequency filters, antenna matching, impedance matching, switching power supplies, analogue filters, and other types of electronic circuits. Its design also allows for improved inductance, high saturation current, temperature characteristics, high Q factor, and low DC resistance.
