The ACF321825-681-TD01 module is a type of EMI/RFI filter comprised of LC, RC Networks. It is used in a variety of applications in order to reduce the amount of electromagnetic interference (EMI) or radio frequency interference (RFI) that may be present in the external environment. It is commonly used in mobile phones, medical equipment, vehicles, aircraft, and military applications, as well as in many other industries. This article will discuss the application field and working principle of the ACF321825-681-TD01.

The ACF321825-681-TD01 module is designed to reduce the amount of interference present in the environment. It is composed of two inductors, two capacitors, and a diode which all work together to provide filtering of EMI/RFI. The inductors provide a low-pass filter, which eliminates high frequencies, and the capacitors provide a high-pass filter, which eliminates low frequencies. Additionally, the diode is used as a clamp in order to prevent voltages that are higher than the rated maximum voltage from passing through the filter.
