Common Mode Chokes are the preferred choice for electrical noise suppression in many applications. There are several types of common mode chokes available in the market which are categorized on the basis of voltage and current ratings, form factor, and working principle. One such common mode choke is the CM9900R-127, which is of the epoxy line-filter type.

Applications of the CM9900R-127

The CM9900R-127 is a very versatile common mode choke which is suitable for a wide range of applications including but not limited to electronic ballasts, LED drivers, motor drives, industrial control systems, and solar inverters. It is especially suitable for switching power supplies with its high power rating and low leakage current. Due to its very low insertion loss and wide range of working frequencies, it can be used in Ethernet, CAN, and Profibus networks as well. Its ultra-compact design makes it suitable for use in equipment with limited space constraints.

Working Principle of the CM9900R-127

The CM9900R-127 is a high performance common mode choke which works on the principle of inductive noise elimination. It operates by using inductive coils which create magnetic fields which inhibit the transmission of noise through the electrical lines. The inductive coils act as an effective countermeasure for common mode noise, RFI, and EMI. The choke has two terminals, one for the signal line and one for the ground. As the current in the signal line passes through the coils, the magnetic field created blocks the noise from propagating, thus preventing it from reaching any other sensitive components connected to the system.

Advantages of the CM9900R-127

The CM9900R-127 offers several distinct advantages over other types of common mode chokes. It is highly effective in reducing common mode interference in electronic circuits and high-speed data buses. It is also much more compact than other available common mode chokes, making it suitable for use in equipment with space constraints. Additionally, it requires minimal maintenance which makes it an ideal choice for continuous use applications. Furthermore, it is easy to install and thus requires no technical expertise for its installation or operation.

Conclusion

The CM9900R-127 is highly suitable for use in a wide range of applications due to its effective noise suppression, compact design, and easy installation. It offers use with both low and high frequency signals and provides excellent protection from noise interference. Owing to its solid build and high power rating, it is perfect for use in industrial, commercial, and residential systems.
