Power Line Filter Modules have long been used in protecting electronics, power tools and other electrical equipment against external interference and noise. One such module is the NAH-30-472-D. This module is designed to reduce EMI/RFI emissions and protect sensitive circuits from external noise.

Overview

The NAH-30-472-D Power Line Filter Module is a high-performance EMI filter with a compact Footprint of 30mm x 34mm. It features a two-stage filtering design using a low pass filter and a high pass filter on the output stage. The low pass filter is used to reduce impulse noise and other frequencies in the kHz range, while the high pass filter is used to reduce common mode noise and other frequencies in the 100 to 500MHz range. The filter module is also rated for a maximum current of 40A, so it can handle a wide range of applications.

Application Field

The NAH-30-472-D Power Line Filter Module is an ideal choice for those seeking to reduce interference in a variety of applications. Its low pass filter can provide good noise rejection for power line applications, such as consumer electronics, industrial equipment, and medical equipment. Meanwhile, its high pass filter can be used to reduce interference from high-frequency sources, such as radio transmitters and cellular towers. The NAH-30-472-D can also be used to protect sensitive circuits from high voltages, transient events, and other forms of signal noise.

Working Principle

The working principle of the NAH-30-472-D Power Line Filter Module is fairly straightforward. The module is designed to accept an input signal, which is then reduced by the low pass filter. The low pass filter removes unwanted signal frequencies, such as impulse noise and other kHz range frequencies. The remaining signal is then passed through the high pass filter, which further reduces common mode noise and other frequencies in the 100 to 500MHz range. The reduced signal is then output from the module.

The NAH-30-472-D Power Line Filter Module is an effective tool for protecting sensitive circuits from external noise, and can be used in power line applications, radio transmitters, and cellular towers. Its compact design and high current rating make it a great choice for most noise-reduction applications.
