Fixed inductors are three-terminal passive components found in electronic circuits. The ASPI-0403H-3R9M-T is a ferrite bead type fixed inductor with a nominal impedance of 3.9 ohms, designed to filter high frequency noise in applications such as LCD TVs, mobile phones, and laptop computers. Its low profile and size make it well-suited for use in both through-hole and SMD (Surface Mount Device) applications in a wide range of communication, consumer electronics, and automotive applications.

The ASPI-0403H-3R9M-T is an inductor with three terminals; a terminal at each end, and one in the center. The two terminals at the ends are the inductive winding, and the one in the center is the ground terminal. The inductive winding is made of copper wires. The ground terminal is sandwiched between two ferrite core beads that act as a shield against EMI and RFI radiation. The terminal is connected to the ground plane and the PCB (printed circuit board).

The ASPI-0403H-3R9M-T works on the principle of Faraday’s law of induction. When current flows through an inductor, it creates a magnetic field which then induces a voltage across the component. The voltage is inversely proportional to the rate of change of the current. This means that when the current decreases, the voltage increases and vice versa. This voltage drop is what is known as inductive reactance. The ASPI-0403H-3R9M-T is designed to filter high frequency noise by introducing inductive reactance, which reduces the current and thus the noise. This inductor is also used in applications such as noise suppression, filtration, and energy storage.

The ASPI-0403H-3R9M-T is a low-profile, small size fixed inductor that is suitable for both through-hole and SMD applications. It is designed to filter high frequency noise, suppress noise, provide filtration, and store energy. Its three-terminal design and ferrite core beads make it an ideal choice for communication, consumer electronic, and automotive applications. With its wide range of applications and working principle, the ASPI-0403H-3R9M-T is a versatile and reliable inductor.
