Common Mode Chokes
Common Mode Chokes (CMC) are developed to suppress emission interference in high-voltage, high-frequency systems by transferring common mode interference voltages to the ground in a distinctly different manner than an inductor or transformer. They are commonly used to maintain signal integrity in systems that have long cables subject to high signal frequencies and interference. CMCs are also referred to as common mode filters or inductors.
Types of Common Mode Chokes
Common mode chokes come in many varieties and are made from a variety of materials and styles. The most popular type of CMC is the shielded ferrite core type. Other varieties include planar spiral, wind toroidal rings, and integrated transformer inductors. Shielded ferrite core CMCs are available in both surface mount (SMT) and through-hole (THT) configurations.
CPFC54-250C-OW Application Field and Working Principle
The CPFC54-250C-OW is a common mode choke manufactured by TDK Corporation. This device is a shielded ferrite core type common mode choke which features a frequency range of 40 kHz - 1.3 GHz, typical inductance of 240 mH, and a resistance of 12 ohms. The physical size of this choke is 54 mm in length and 23 mm in diameter. It is ideal for applications such as LED lighting, such as LED TVs, and other applications which require a high-frequency signal.
The working principle behind the CPFC54-250C-OW common mode choke is to reduce the amount of common mode currents and voltages flowing through a system. This is accomplished by a combination of the shield and magnetic core material acting together to limit the amount of interference. The shield serves to protect the signal transmission from external sources, while the magnetic core acts as an inductor to reduce the common mode current and voltage. By limiting the amount of interference, the signal is optimized for high frequency and low noise transmission.
Conclusion
Common Mode Chokes are an important component for high frequency, high voltage systems. The CPFC54-250C-OW is a popular choice for these applications due to its compact size, high frequency range, and low resistance. The combination of the shield and magnetic core material works together to reduce common mode currents and voltages in the system, allowing for more efficient signal transmission.
