Fixed inductors are specialized components used in many electrical and electronic applications. They are, as the name implies, fixed in their properties, meaning that they are not adjustable. This is in contrast to variable inductors, which are adjustable components used mainly in radio frequency (RF) circuits. The ETQ-P4M1R0KVC is a type of fixed inductor and it is typically used in low-power or average-power applications, such as switching power supplies, LED lighting, telecom, battery charging and other consumer and commercial products.

The ETQ-P4M1R0KVC fixed inductor is a radial-leaded, surface-mount device that has been designed to provide optimized performance and reliability. It offers a rated inductance of 4.7 μH ±20% at 100 kHz and 0.001 mH, and it also has a temperature range of -40 to 105°C. This type of inductor may be subject to additional testing, such as resistance to moisture and solvents, depending on its application. It may also undergo additional strength tests, including drop tests.

The working principle behind the ETQ-P4M1R0KVC is based on electromagnetic induction. This phenomenon occurs when a varying electric current is passed through a coil of wire and produces an electromagnet. The electromagnet then induces an electric current in a separate coil of wire. This current flow is known as magnetic flux, and the rate of change of the flux through the coil is proportional to the rate of change of the electrical current. This is known as the inductance of the air gap between the two coils and it is what ultimately determines the electrical properties of the fixed inductor.

The ETQ-P4M1R0KVC inductor features an optimized air gap that provides excellent switching performance, as well as minimal heat dissipation. Its advanced construction is designed to minimize noise and improve power supply stability. The inductor’s low profile makes it suitable for use in tight spaces, and its radial legs make it easy to install. It also features an extended operating temperature range and is highly resistant to moisture and other environmental factors.

The primary application field for the ETQ-P4M1R0KVC is for use in low-power or average-power circuits, particularly in switching power supplies, LED lighting, telecom, battery charging, and other consumer and commercial products. It is also suitable for automotive, audio, and medical applications, as well as various industrial settings. The optimized air gap construction of this fixed inductor makes it well-suited for switching applications, and its extended operating temperature range and robust construction make it an excellent choice for applications requiring reliability and durability.
