Fixed Inductors: HKQ0603S22NH-T Application Field and Working PrincipleInductors, or commonly known as coils, are electrical components mainly used in radio frequency, audio, telecommunication, and other resident electronic equipment. Their main purpose is to store energy in the form of a magnetic field, similar to a capacitor. Fixed inductors are distinct from other inductors in that they are not variable in their reactance, and thus, their inductance is fixed.An example of a fixed inductor is the HKQ0603S22NH-T. This is a surface-mount type inductor that can be adapted for use in many applications and is ideal for switch mode power supply applications and wide frequency required circuit designs.Application FieldThe HKQ0603S22NH-T is capable of offering a wide range of applications across numerous fields. Some of them include, but are not limited to, DC-DC converters, step-down peak current-mode DC-DC converters, and DC-DC linear regulators. They are suitable for high current applications such as electric vehicles and laptop power supplies. It is also suitable for automotive applications such as actuator/sensor coils, boost converters, digital power supplies, and non-contact power transfer applications.Working PrincipleAn inductor works on Faraday\'s Law of Induction which states that the voltage induced in a coil is proportional to the rate of change of the magnetic flux. However, the actual effect of an inductor is dependent on its inductance, which is determined by the length of the coil, number of turns, radius, and permeability of the core.The inductance of the HKQ0603S22NH-T is fixed at 22nH, making it suitable for high-frequency applications, while its saturation current is 1.4A and core loss is 0.0541W. The fact that its inductance is fixed also makes it suitable for switch-mode applications, meaning that the current will not be affected significantly by the change of voltage or frequency.It also offers temperature stability and a low DC resistance, which makes it suitable for high frequency/high current applications. Moreover, its effective balanced magnetic material also ensures low core losses during the operating frequency.Overall, the HKQ0603S22NH-T is a reliable and efficient fixed inductor that can be used in a variety of applications. From DC-DC converters to switch mode power supplies, it can be adapted to each application due to its excellent performance and efficient energy storage capabilities.
