Fixed inductors are electrical components that are made from a conductive material (usually copper or aluminum wire) tightly wound on a metallic core. They are used in many electronic circuits to store electrical energy, filter signal frequencies, or to provide impedance matching. The HKQ04021N5B-T is a fixed inductor with an inductance of 0.41uH and a maximum current of 210mA. It is constructed in a traditional cylindrical housing with a pin size of 5.2mm x 10mm, which makes it suitable for use in both through-hole and SMD applications.

The HKQ04021N5B-T is a surface-mountable device designed for use in high-frequency, power-conversion circuits. The inductor features an epoxy-coated core that improves current-handling capability and prevents the inductor’s windings from being exposed to any external environments – making it an ideal choice for use under harsh conditions. The inductor operates at a frequency range of 0.5MHZ to 2.5MHZ and at temperatures as low as -40℃ to as high as +85℃.

The HKQ04021N5B-T’s application field encompasses automotive, computing, communication, consumer, and industrial applications, with particular focus on switching power supplies and power converters. In automotive applications, it can be used for boosting power to fuel injection systems, dashboard lighting, interior lighting, and audio systems. In consumer electronics, its main uses include home appliances, computers, smart TVs, and game consoles. In the industrial field, it is often used in inverters, solar panels, and wind turbines.

The working principle behind an inductor is the basic law of electromagnetic induction, which states that when a current flow in a coil, a magnetic field is created. This magnetic field can then induce a voltage in a nearby coil, which is called mutual inductance. An inductor uses this concept to store electrical energy in the form of a magnetic field. The magnitude of this stored energy depends on the inductor’s inductance value, as well as the amount of current flowing through it.

The HKQ04021N5B-T uses its low DC resistance and high saturation current to reduce the amount of power lost in the inductor when it is carrying high levels of current. This helps to improve the efficiency of the system as a whole. Additionally, the inductor’s high permeability core reduces the size of the device and allows it to fit into tight locations.

The HKQ04021N5B-T is a versatile fixed inductor that can be used in a wide variety of applications due to its low DC resistance, high saturation current, and epoxy-coated core. It is an ideal choice for use in high-frequency, power-conversion circuits due to its capability to store electrical energy, filter signal frequencies, and provide impedance matching.
