Fixed Inductors are components, which are used to store magnetic energy, and when experiencing an increasing or decreasing current, induce the opposing change in its current. The most common type of fixed inductor is the lossless coil, which is a passive component without any internal power sources. The most common applications of these devices are power supplies, DC/DC converters, switched-mode power supplies, amplifiers, and filters. In the electronics industry, the HKQ0603U3N1S-T is a common type of fixed inductor. It is an axial leaded, surface mountable device with a 3mm (0.12”) body height. Its design includes a ferrite core with an air gap, which is an important feature for power applications. The inner coil technology allows for very low resistance, resulting in improved power handling capabilities, and reduced thermal losses compared to other types of coils.The HKQ0603U3N1S-T is primarily used in high-frequency switching and driver applications, and is commonly found in AC-to-DC power adapters, DC-DC converters, motor drivers, and industrial systems. Its small size allows it to be used in applications where space is limited, and its performance and stability over a wide range of current and voltage makes it a popular option with system designers. The working principle of the HKQ0603U3N1S-T is based on Faraday\'s law. At a given current, the induced voltage across the device is equal to the time rate of change of the magnetic flux within its core. As such, when a positive or negative current is applied to the device, the oppositely directed voltage is induced. The magnetic flux stored within the core of the device is proportional to the current flowing through it. At a given fixed current, the stored magnetic flux remains the same, producing a value of inductance which is proportional to the current. This is why the inductance of the device is referred to as a ‘lossless’ inductor, as the energy is not dissipated but stored in the core during current changes.The inherent characteristics of a fixed inductor make it an ideal device for filtering high-frequency energy, and for smoothing out voltage changes in power supplies. In addition, they are widely used to store energy for triggering devices, and for creating sinusoidal current output from an AC-DC power supply. An important consideration when designing with the HKQ0603U3N1S-T is its current handling capability. Its wide inductance range is suitable for various applications, from low current diode steering to high current switching applications, and its power handling capabilities make it a practical choice for many DC-DC converter designs. Overall, the HKQ0603U3N1S-T is a versatile and reliable fixed inductor, which can be used in a range of applications. Due to its low resistance and high power handling capability, it can be used in power supply, AC-DC adapter, and DC-DC converter designs, as well as a range of other applications. Its inherent characteristics and design features make it an ideal solution for designers seeking a low-cost, space-saving component capable of meeting their power requirements.
