Power Line Filter Modules have become an increasingly vital component in electronics manufacturing due to their ability to protect equipment, systems, and people from hazardous voltage. B84144A0090R120 is an example of such a power line filter module, offering protection from voltage transients in different applications. In this article, we will discuss the application fields and working principle of B84144A0090R120.

B84144A0090R120 is a single-phase AC power line filter module and is suitable for filtering in 2-wire AC main socket applications. The filter is designed to filter EFT pulses, high-frequency switching transients, high-frequency spikes, and surge pulses from AC mains. The filter comprises a ferrite core with two wire windings that filter different AC power ranges, making it suitable for both single-phase applications and three-phase applications.

The filter can be used in various application fields such as telecommunications, medical equipment, computering, audiovisual equipment, industrial automation, home appliances, automotive, etc. It helps to protect sensitive components in these various application fields from the harmful effects of electromagnetic interference (EMI) and radio-frequency interference (RFI).

In addition to protecting against EMI and RFI, the filter also offers protection from overvoltage and undervoltage too. This is achieved through the use of overvoltage protection components, such as varistors and transient voltage surge suppressors (TVSSs), incorporated into the design. These components block any overvoltage surges from passing through the filter and damaging the sensitive components.

The working principle of the B84144A0090R120 filter is based on the fact that any electric current flowing through a conductor generates a magnetic field. This field will induce an electric current in any other conductor in close proximity, and this induced current is known as a transient voltage. The filter works by intercepting these transient voltages and diverting them into the filter housing, where they are dissipated as heat. This helps to protect the sensitive components from transient voltages.

The B84144A0090R120 filter also offers ESD protection. ESD, or electrostatic discharge, is a sudden release of static electric energy, usually created when two objects come into contact. The filter serves to divert any electrostatic discharge energy away from the connected components. This helps reduce the risk of components being damaged by ESD.

In summary, B84144A0090R120 is a single-phase AC power line filter module that offers protection from EMI, RFI, overvoltage, undervoltage, and ESD. It has been designed for use in a variety of applications and provides effective protection from transient voltages. The filter works by intercepting the transient voltages and dissipating them as heat.
