Power Line Filter Modules provide advanced protection from electrical disturbances caused by electromagnetic interference (EMI) and radio frequency interference (RFI). The B84143G20R112 is a power line filter module designed to reduce electrical noise applications. This article will discuss the application field and working principles of B84143G20R112.

The B84143G20R112 is an AC filter module with a voltage range of 85 to 265 volts. It is suitable for use in a wide range of applications, from home audio systems to industrial machinery, such as pumps and compressors. The wide voltage range allows it to be used in a variety of different environments, such as high-voltage industrial settings and operations requiring low-voltage solutions. It is also suitable for use in applications requiring EMI and RFI reduction. This filter module can be used in high-frequency switching applications to reduce conducted and radiated emissions as well as reduce the effect of conducted and radiated interference on electronic equipment.

The B84143G20R112 has three independent power lines that allow for customization to meet specific requirements. The lines are connected in parallel for better current capacity. It is designed to have a maximum of 1000 kilohertz (kHz) pass band width with a minimum of 30dB attenuation from 30kHz to 1000kHz. The filter module also has a dV/dt rating of 7kV/μsec, making it ideal for fast switching applications. Finally, it features an environmental temperature range of -55 to +105°C, so it can handle harsh environments.

The working principle of the B84143G20R112 is based on the use of inductance, capacitance and resistance to reduce electrical noise. The inductor and capacitor form an LC filter circuit, which acts as a low-pass filter. This filter reduces the amplitude of signals above its cutoff frequency and passes signals below its cutoff frequency. The resistor is used to limit the current and dissipate the heat generated by the other components. The combination of the inductor, capacitor and resistor allows the filter to reduce both conducted and radiated interference.

The B84143G20R112 filter module is a powerful and reliable device designed for a wide range of applications. Its wide voltage range, frequency response, dV/dt rating and environmental temperature range makes it suitable for a variety of applications, including high-frequency switching applications and general interference reduction. Its working principle is based on the use of inductance, capacitance and resistance to reduce electrical noise. It is an excellent choice for reducing conducted and radiated interference.
