ACF321825-220-TD01 EMI/RFI Filters (LC, RC Networks)

ACF321825-220-TD01 is a type of EMI/RFI filter used in power supplies and other applications to reduce the risk of interference. The filter combines both inductive (LC) and capacitive (RC) networks and is designed to protect electronic circuits from electromagnetic interference (EMI) and radio frequency interference (RFI).

Application Field

The ACF321825-220-TD01 filter is suitable for many different applications, including power supply, board-level, and system-level. It is ideal for use in applications ranging from mobile phones to industrial control systems, medical equipment, and other commercial and consumer electronics. It is also suitable for applications including servers, personal computers, and other digital equipment. The ACF321825-220-TD01 can also be used for automotive, military, and aerospace applications, as well as for other applications requiring high-frequency noise reduction.

Working Principle

The ACF321825-220-TD01 filter works by combining inductive (LC) and resistive (RC) networks. These networks are designed to reduce the amount of energy passing between the input and output of the filter, reducing the risk of EMI/RFI radiation. The filter uses an inductor-capacitor (LC) network at the input and a resistor-capacitor (RC) network at the output to form a low-pass filter. The LC network reduces the high-frequency noise and the RC network reduces the low-frequency noise. The filter also incorporates additional components including varistors, fuses, spark gaps, and other features to provide further noise reduction and protection.

The ACF321825-220-TD01 filter is designed to be highly efficient and have a low insertion loss. It is designed to meet high levels of EMI/RFI radiation and meet MIL-STD-461C or FCC emission requirements. The filter also meets UL safety requirements, ensuring that the design is safe for use in consumer applications.

Conclusion

The ACF321825-220-TD01 is a type of EMI/RFI filter designed to protect electronic circuits from EMI/RFI radiation. The filter combines both inductive (LC) and capacitive (RC) networks and is suitable for a variety of applications. It is designed to be highly efficient and meet high levels of EMI/RFI radiation and MIL-STD-461C or FCC emission requirements. The filter also meets UL safety requirements, ensuring that the design is safe for use in consumer applications.
