Fixed inductors, also known as inductance devices, are electric components that limit the maximum amount of current in the circuit in order to prevent damage to other components. An ETQ-P6F2R0LFA is an example of a fixed inductor. Its applications and working principles are discussed in this article.

Application Field

The ETQ-P6F2R0LFA is a surface-mount inductor. It is used mainly in cellular phones and other electronic devices due to its compact size and low cost. It is suitable for use on printed circuit boards, offering high stability along with excellent regulation performance.

It can also be used in a variety of other applications. Its low-profile size makes it ideal for radio-frequency (RF) circuits, as it can provide a degree of isolation for two different frequency bands. It is also commonly used in power convertors in order to reduce the amount of electromagnetic interference (EMI) generated.

Working Principle

An inductor is a passive component, meaning that it does not need a power source to operate. Instead, it works by inducing a voltage in a closed circuit due to the flow of current. This voltage is typically referred to as “back electromotive force” (EMF).

The amount of EMF produced by an inductor depends on three factors: the amount of current flowing through the circuit, the size of the inductor, and the type of material used to make it. Typically, the larger the inductor size and the more current flowing through the circuit, the higher the EMF.

The ETQ-P6F2R0LFA has a rated inductance level of 5N7H, meaning that 5N7H is the amount of back EMF it produces when 2 amps of current are flowing through it. It also has an impedance level of 30.6 Ohms, meaning that at a given frequency its in-phase impedance will be 30.6 ohms.

The ETQ-P6F2R0LFA is typically used in high-frequency applications, as its impedance is lower at higher frequencies, allowing more current to flow through the circuit without creating high levels of back EMF. This is because the inductor’s size is sub-optimal for lower-frequency applications, and its core materials are not optimized for low-frequency applications.

Conclusion

The ETQ-P6F2R0LFA is a fixed inductor with a variety of applications. It is typically used in cellular phones and other electronic devices due to its small profile and low cost. It also has a rated inductance level of 5N7H and an impedance level of 30.6 Ohms, making it suitable for high-frequency applications. By understanding its applications and working principles, designers can ensure that this inductor is correctly applied in their circuits.
