Fixed Inductors

Fixed inductors are electrical components constructed with a wire arranged in a loop and a core material inside the loop. The wire is usually made of copper or aluminum, and the core is made from powdered iron or ferrite. There are many different types of fixed inductors, with different construction properties and characteristics, which suit different applications.The HK100539NJ-T is a type of fixed inductor with a non-polarized construction, meaning that it does not have a positive or negative terminal. This type of inductor is suitable for both AC and DC applications. The inductance of the HK100539NJ-T is 390 nH, with a DC resistance of 0.135 Ohm. It has an operating temperature range of -40˚C to +85˚C, a self-resonant frequency of 2.8GHz, and a current saturation of 0.95 Ampere.The HK100539NJ-T is used in a variety of DC/DC converter applications due to its low resistance, high inductance, and stable temperature range. It is also used for switching power supplies or charge pumps, as it is able to maintain its inductance throughout the frequency range. The HK100539NJ-T is typically used with an electrolytic capacitor in order to increase the working frequency range and also to reduce the resistance of the circuit.The working principle of a fixed inductor is based on Faraday’s law of induction, which states that a changing magnetic field generates an electric field, and vice versa. This property is the basis of operation of the HK100539NJ-T. As current flows through the inductor, it creates a magnetic field around it, which induces a voltage across the inductor terminals. The voltage is then used to provide power to other components in the circuit.In addition, the core material of the HK100539NJ-T has higher magnetic permeability, which makes it more efficient. This allows the inductor to store more energy than other types of inductors, which makes it well suited for high frequency applications and allows it to handle higher current levels.The HK100539NJ-T is also used in a wide range of analog circuits. It can be used as a low-pass filter, allowing low frequencies to pass through, while rejecting high frequencies. It is also used as a voltage regulator, where the inductor helps reduce voltage fluctuations by regulating the current.In addition, the high inductance of the HK100539NJ-T makes it suitable for use in resonant or oscillator circuits, where the inductor is paired with a capacitor to create an LC (inductor and capacitor) circuit. The LC circuit has the ability to resonate, meaning it will oscillate at a specific frequency when a voltage is applied across it.Overall, the HK100539NJ-T is a versatile fixed inductor that can be used for a variety of electronic applications. Its low resistance, high inductance, and wide temperature range make it ideal for power conversion and analog circuit designs. Furthermore, its self-resonant frequency and current saturation make it suitable for high frequency operations and circuits requiring higher current levels.
