Common Mode Chokes (CMS 1-5-R) are effective filtering components that protect electronic equipment from interference and prevent transient voltages from affecting sensitive devices. They are used in a wide variety of applications, including automotive, industrial, medical, and aerospace. They are particularly effective in noise rejection and are especially useful for eliminating high frequency noise in the ICs (Integrated Circuits).

The CMS 1-5-R application field is composed of a smooth filter core with high electrical field oscillation frequency. The filter is designed to control the leakage flux to avoid signal interference and reduce power supply noise. The fields of application for CMS 1-5-R range from automotive, industrial and aerospace fields to medical and home pre-wi-fi. It is a multi-functional EMI/RFI filter, which protects against high-frequency electrical interference.

The CMS 1-5-R working principle can be understood by considering its characteristics. The EMI filter is designed to reject the high frequency interference and hence the low frequency signals will be passed through without any attenuation. The filter has two types of coils which are connected with a pair of capacitors. One coil is designed for common-mode rejection and the other coil is designed for differential-mode suppression. The capacitors pass the high frequency signals without any attenuation. The filter cores and the capacitors are encased in a special material which can block the leakage flux.

When interference occurs between input and output circuit, the coils and capacitors in the filter will block the high frequency interference, allowing only the low frequency signal to be passed. The filter helps to reduce the susceptibility of the components to noise and thus improve their performance. The efficient working principle of the filter makes it ideal for use in various types of applications such as Ethernet signal transmission, power line conditioning, power filtering, and signal conditioning.

CMS 1-5-R filters are designed to reduce the performance degradation caused by common noise sources such as RFI and EMI. Common-Mode Chokes are typically used in a variety of demanding applications, including military, commercial, medical and aerospace. These filters can also be used in automotive, home pre-wire and many other applications. They are installed in many places, such as printed circuit boards, computer systems, and power supplies. By protecting against interference, they help ensure the efficient operation of electronic components and systems.
