Common Mode Choke (CMC) is a device used to prevent electrical signals from travelling along parallel paths; it works to protect electrical communications systems by suppressing the passage of signal currents. The CM9900-474 is a specific type of CMC designed for applications with extreme frequencies. It works by reducing the electrical strength of the signals or noise travelling along power or control lines. This article will discuss the CM9900-474 application field and working principle.

The CM9900-474 is mainly used in high-frequency and high-noise applications such as computers, mobile phone chargers, laptops, servers, networks, and communication systems. This type of CMC provides superior noise suppression in these applications; it can reduce common mode currents up to 50 kHz and effectively reduce both high frequency and low frequency interference. In addition to the advantages of wide range common mode current suppression, the CM9900-474 also has excellent transmission line protection ensured by its fast response time and wide range of inductance values.

The working principle of the CM9900-474 is based on magnetics. It is composed of multiple ferrite core components, which have the ability to absorb and divert current in different directions. As the current of the signals enters the CMC, it is divided into alternate parallel paths, preventing them from travelling along one path. This reduces the power or strength of the signals or noise, as they are forced to travel different directions and through different mediums. As a result, the electrical signals or noise are effectively suppressed.

In addition to its superior noise suppression, the CM9900-474 has excellent temperature durability and wide frequency range. It can operate under temperatures ranging from -30 to 85°C without overloading the system. Its frequency range ranges from 1M to 400M, so it can also be used in applications with extreme frequencies. Additionally, the CM9900-474 is built with high-grade material to eliminate sudden power loss and ensure maximum performance.

The CM9900-474 CMC is a versatile device suitable for high noise applications. Its wide frequency range and fast response time ensure superior noise control and environment protection. Its excellent temperature and durability make it a reliable device in various harsh conditions. For those looking for a robust CMC for high noise applications, the CM9900-474 is an excellent choice.
