Power Line Filter Modules 3-1609091-3: Application Field and Working Principle

Power Line Filter Modules are designed for EMI/RFI suppression in power distribution networks. This type of filter module is used to attenuate the electrical noise, or electromagnetic interference (EMI) and radio frequency interference (RFI), produced by both commercial and residential electrical equipment such as computers, microwaves, and power tools. The 3-1609091-3 power line filter module is a multi-stage passive filter designed to provide high frequency noise suppression from 30MHz to 1.2GHz.

Application Field

The 3-1609091-3 power line filter module can be used in a variety of applications. Its ability to provide EMI/RFI suppression makes it an ideal choice for industrial, commercial, and residential applications. These applications include, but are not limited to, power converters, gaming consoles, computers, audio/visual equipment, telecommunications, and automotive. The 3-1609091-3 power line filter module can also be used as a standby protection circuit against lightning strikes and other environmental surges.

Working Principle

The 3-1609091-3 power line filter module utilizes a combination of inductor and capacitor elements to attenuate and filter out both high and low frequency electrical noise. These elements are arranged in a series-parallel configuration to form multiple low-pass filter stages. The inductor elements act as current shunts to block the passage of high frequency energy and the capacitors act as low-pass filters to block the passage of low frequency noise. The resultant combination of inductors and capacitors provides a low-pass filter with a cutoff frequency that is much lower than the filter cutoff frequency of single element filters. The 3-1609091-3 power line filter module also utilizes thermistors to provide additional protection against transients and inrush current. These thermistors, along with the filter stages, form a protective shield against high-frequency electrical noise, EM and RF interference, as well as power surges and transients.

Conclusion

The 3-1609091-3 power line filter module is a multi-stage passive filter designed to provide high frequency noise suppression from 30MHz to 1.2GHz. It is an ideal choice for both commercial and residential use and can be used in converters, gaming consoles, computers, audio/visual equipment, telecommunications, and automotive applications. Its combination of inductor and capacitor elements, along with its thermistors, provides a low-pass filter with a cutoff frequency that is much lower than the filter cutoff frequency of single element filters. This allows it to provide efficient EMI/RFI suppression and protection against lightning strikes and other environmental surges.
