Power Line Filter Modules

The NAH-30-472 power line filter module is a common solution used in a wide range of electronic equipment to reduce electromagnetic interference (EMI). Its primary purpose is to prevent high frequency noise from entering or exiting the equipment’s power supply. The module combines a series inductor, capacitor, and other components into one compact and easy to install unit.

Applications

The NAH-30-472 power line filter module is intended for use in a variety of applications. These include DC-DC converters, AC-DC converters, LED lighting systems, power supplies, and other noise sensitive electronics. It is suitable for electronic systems operating from either DC or AC power sources.

EMI Mitigation

The NAH-30-472 power line filter module acts as a low-pass filter to attenuate high frequency emissions from entering or exiting the power supply of the system. This reduces the amount of EMI escaping the system and helps ensure regulatory compliance. It is also beneficial for systems operating in noisy environments, as it can provide additional EMI mitigation.

Working Principle

The inner workings of the NAH-30-472 power line filter module are fairly simple. The module consists of an inductor, capacitor, and other components. The inductor stores energy in its magnetic field, and the capacitor stores energy in its electric field. Together, these components create a filter which only allows low frequency signals to pass. This prevents higher frequency noise from entering or exiting the power supply.

Conclusion

The NAH-30-472 power line filter module is a common solution for reducing EMI in electronic systems. It is suitable for applications operating from both DC and AC power sources. The module consists of an inductor, capacitor, and other components. Together, these components create a filter which only allows low frequency signals to pass. This prevents higher frequency noise from entering or exiting the power supply, helping to ensure regulatory compliance and improved system performance.
