ETQ-P3H1R4BFA is a fixed inductor that has a wide range of uses in electronic circuits. The inductor is mainly used to store energy, provide inductance, and regulate current flow. It is commonly used in power electronics, automobile electronics, and communication systems. It is also used in switching converters, such as inverters, DC-DC converters, resonant-mode converters, and PFC (Power Factor Correction) converters.

The ETQ-P3H1R4BFA fixed inductors are made of high-frequency material with an iron core. It has a maximum current rating of 3A and a maximum DC resistance of 0.44Ω. The inductance of the device is 4.2uH and it has a self-resonant frequency of 280MHz. The device is also RoHS compliant and UL listed according to its safety standards.

The inductor’s working principle relies on the principle of electromagnetic induction. It creates a magnetic field around the inductor’s core when electrical current is passed through it. This creates an opposing magnetic field and the magnetic fields of the two opposing fields will interact in a process called induction. This interaction causes the electrical current to be induced in the inductor’s core, creating a voltage drop. The amount of voltage drop is dependent on the amount of inductance and the amount of current.
