Power Line Filter Modules

Power line filter modules are designed to reduce interference between appliances and other sources of unwanted noise. The NBC-20-332 module operates on frequencies ranging from 12kHz to 500kHz and is designed to filter both common-mode and differential-mode noise. It can be used to filter out interference from AC and DC power sources, as well as other sources such as fluorescent lights, dimmer switches, and electric motors. Its use is recommended for applications such as home electronics, personal computers, medical devices, and audio systems.

Working Principle

The NBC-20-332 module works by using ferrite cores to filter out the unwanted noise. It consists of two separate channels for common-mode and differential-mode noise. The common-mode noise is filtered out by a pair of cores that are placed in parallel. The two cores are arranged in such a way that the flux lines cancel each other out, thus effectively eliminating the unwanted noise. The differential-mode noise is filtered out by two identical cores that are placed in series. The cores act as a capacitor, allowing only the desired signal to pass through and blocking out any unwanted noise. The module also includes a power line filter, which helps reduce high voltage spikes and other related interference.

Application Field

The NBC-20-332 module is commonly used in noisy electrical environments where interference needs to be reduced or eliminated. Examples of such environments include industrial and commercial facilities, medical laboratories, home electronics, control systems, and audio systems. The module is also suitable for automotive applications, as it is designed for both high and low voltage applications. Additionally, its small size and low cost make it a great choice for low-volume production applications.

Conclusion

The NBC-20-332 power line filter module is a powerful and cost-effective solution for reducing electrical interference from both AC and DC power sources. Its use is recommended for applications such as home electronics, medical devices, and audio systems, as well as industrial and commercial facilities, medical laboratories, and automotive applications. The module works by using two pairs of ferrite cores, one for common-mode noise and one for differential-mode noise, to filter out interference and noise. Thanks to its small size and low cost, the NBC-20-332 is ideal for low-volume production applications.
