EMI/RFI Filters are internationally standardized low-pass filters used to reduce the electromagnetic interference (EMI) and radio frequency interference (RFI) from electronic equipment. They are also known as LC (inductance-capacitance) or RC (resistance-capacitance) networks.

The CM6400A is a very popular and effective solution in this domain, used in a range of industrial, telecommunications and consumer applications. It provides effective and reliable reduction in both EMI and RFI noise.

The CM6400A is an integrated differential filter with a wide bandwidth from DC to 2GHz, and it features miniature footprints in size from 0201 to 1210. This makes it a great choice for high-density PCBs. It offers effective noise reduction, superior high-frequency attenuation and a wide response curve.

To understand the CM6400A, one must first understand the fundamentals of EMI and RFI and the functioning of LC and RC networks. EMI is defined as the signal interference within a device caused by stray electrical fields, generated by another device. RFI is a different kind of interference and is caused by high-frequency signals in the environment.

An LC or RC network is a passive device consisting of a series of L-C or R-C components connected together in an LC- or RC-circuit. The components are sometimes referred to as "tank" or "trap" circuits. These networks are used to reduce unwanted signals by providing a low-pass filter to the noise-affected signal.

The main purpose of an LC or RC network is to reduce the amplitude of higher frequency signals and allow only the desired frequencies to pass through. In the case of the CM6400A, it has a wide range from DC (direct current) up to 2GHz. As a result, it is able to reduce a wide range of EMI and RFI frequencies, providing effective and reliable protection. It also features a BOM (Bill of Materials) protection feature that prevents component breakdown due to EMI or RFI.

The CM6400A is also designed with advanced ESD protection, making it ideal for high-voltage applications. The filter also features high isolation levels, up to 5dBm, allowing for very effective signal protection. In addition, the filter operates at temperatures from -55°C to 150°C, further improving its reliability in industrial environments.

Overall, the CM6400A is a great choice for applications where EMI and RFI noise reduction is a priority. With its high performance and small form factor, it\'s perfect for a range of industrial, telecommunications and consumer applications. And, with its wide bandwidth and advanced protection, it provides effective, reliable and cost-effective EMI and RFI filtering.
