Fixed inductors are electrical components used in electronic circuits to store electrical energy in the form of a magnetic field. The HKQ040230NJ-E is a fixed inductor with a current range of 0.2A to 0.4A and a voltage range of 4 V to 5 V. It has an inductance of 3.0uH, a self-resonant frequency of 270 MHz, and a tolerance of ± 20%.

The HKQ040230NJ-E has a variety of applications. It is commonly used in high-frequency switching power supplies, LCD displays, telephone switches, and other digital and analog circuits. It is also used in low-noise amplifiers, AC motor controllers, and power supply circuits for small DC motors. In addition, it is used in various automotive electronic control systems.

The working principle of the HKQ040230NJ-E is based on Faraday’s Law of Induction. When a current is applied to the inductor, it creates an electromagnetic field. This field then induces a current in the opposite direction, creating a circular current flow known as a back EMF. The back EMF opposes the applied current, which reduces the effective input current and results in a decreased output current. This is known as inductive reactance. The inductance of the inductor determines the amount of inductive reactance present.

The HKQ040230NJ-E is a high-quality, reliable fixed inductor with a wide range of applications. It has a high self-resonant frequency, a low temperature coefficient of inductance, and is capable of handling high currents up to 0.4A. It also offers excellent thermal shock resistance. All of these features make it a great choice for many different electronic circuits.
