Fixed inductors are electronic components that store and release energy in the form of a magnetic field. Common fixed inductors are used to regulate current, filter signal, increase voltage, and even generate an alternating current. The HKQ04023N9B-T is an example of a fixed inductor.The HKQ04023N9B-T is a low profile, high current, radial leaded power inductor. It features a metal composite core construction with a maximum DC resistance of 0.24 Ohm. It has an inductance range of 2.7 to 3.2 uH and a rated current of 40A. It is an exceptionally reliable inductor, powered by a wide operating temperature range from -55°C to 125°C. Its small size and ease of use makes it an excellent choice for automotive and general-purpose applications.The working principle of a fixed inductor is relatively simple. When a direct current (DC) flows through the inductor coil, a magnetic field is formed. As the current passes through the coil, an inductive voltage is generated. This voltage opposes the current, resulting in a decrease in the voltage and an increase in the current. The inductor stores energy in the form of a magnetic field, which is released when the current is shut off.The main purpose of a fixed inductor is to generate an alternating current. By changing the direction of the electric current, a fluctuating magnetic field is created, which can be used to produce an alternating current. In this case, the ability of the inducer to induce an opposing voltage is paramount. Thus, the strength of the magnetic field created by the inductor is largely responsible for the overall efficiency of the device.Fixed inductors are also used in networks for signal filtering. Filtering includes noise reduction, order preservation, and indirect or direct signal selection. In electronic circuits, capacitors and inductors form the two primary components for producing AC and DC signals, respectively. Fixed inductors are also used to control the voltage in a circuit in order to maximize the performance of highly sensitive electronic devices.In conclusion, the HKQ04023N9B-T is an example of a reliable, high current radial leaded power inductor. It is suitable for automotive and general-purpose applications due to its small size and ease of use. The working principle of a fixed inductor is relatively simple – when a direct current (DC) passes through the inductor coil, an inductive voltage is generated, which opposes the current, resulting in a decrease in the voltage and an increase in the current. Fixed inductors are mainly used to generate an alternating current and for signal filtering.
