Fixed Inductors

Fixed inductors, also known as fixed chokes, are electrical components used in a wide variety of electronic circuits. These are typically used to provide consistent current, create resonant frequency, store energy, and reduce Radio Frequency Interference (RFI). PA4349.202ANLT is a specific type of fixed inductor with usage in the field of low power switching applications, such as low power regulators. It has a robust construction such as a self-hinged cover for electrical isolation and a high finish for corrosion protection. It is also UL and CSA approved.

Application Field

PA4349.202ANLT has a wide range of applications including audio equipment, telecom devices, HVAC systems, automotive audio, and other communication systems. Additionally, they are used in LED lamps, power supplies, and other low power switching applications. The inductor has a working temperature range of -40°C to +85°C with a wirewound construction for low DCR, allowing for low power switching applications with low DCR current.

Working Principle

The working principle of PA4349.202ANLT is based on the principles of magnetic induction and Faraday’s law. This involves the flow of electric current through a coil which creates a magnetic field that induces an electromotive force (EMF) in the coil. This EMF is the inductance, which is the opposition of the flow of electric current. So, the inductance is a measure of the opposition to current flow, with higher inductance having more resistance. PA4349.202ANLT has a high inductance of up to 1.2 mH, making it suitable for use in low power switching applications.

Conclusion

PA4349.202ANLT is a fixed inductor designed to fulfill the need of low power switching applications. It works on the principles of magnetic induction and Faraday’s law, generating a high inductance of up to 1.2 mH. This makes it suitable for use in audio equipment, telecom devices, LED lamps, automotive audio, HVAC systems, and other communication systems.
