NAH-20-331-D

NAH-20-331-D is a power line filter module that can effectively reduce electromagnetic interference (EMI) in a power system. It is mainly used in power supplies, frequency converters, switching power converters, inverters, power amplifiers and other electronic equipment. The filter module is designed to reduce the ripple noise frequency of the power supply and filter out the EMI between different power supplies.

The basic principle of NAH-20-331-D power line filter module is the magnetic and electric field coupling effects. There is serial inductors and capacitor outside of the filter module, and these inductors form an LC filter network with each other. The inductor can form a magnetic field outside the filter module, and the capacitor can prevent the interference current from flowing in the circuit. When the high frequency noise enters the power line, it passes through the inductor, the LC filter network can absorb the high frequency noise, and the capacitor will reduce the output current change which can guarantee the output voltage accuracy. The filter module can reduce the high frequency interference effectively and ensure the power system stability and accuracy.

The NAH-20-331-D power line filter module has high inductance and low capacitance performance, which will reduce the switched frequency of the filter module to lower frequency, and reduce the interference noise. It is compact in size and has stable performance. It is designed for the EMI and power supply applications that require high frequency noise reduction.

In addition, the NAH-20-331-D power line filter module has a wide operating temperature range and wide frequency range performance. It can reduce the interference caused by frequency conversion from 50HZ to 10kHz. The filter module has a temperature range of -25℃ to +70℃, which allows them to be used in harsh environment. The NAH-20-331-D power line filter module is also equipped with a protective device, which can protect the filter module from lightning strikes and surges.

In summary, the NAH-20-331-D power line filter module can effectively reduce the EMI and provide high frequency noise reduction in the power supply system. The filter module can reduce the ripple noise frequency of the power supply and filter out the EMI between different power sources. It has a wide temperature range, wide frequency range performance and is compact in size. It also has a protective device to protect the filter module from lightning strikes and surges. Therefore, it is a great filter module for EMI and power applications that require high frequency noise reduction.
