Common mode chokes, also known as common mode inductors, are inductor hardware components commonly used in power electronic circuits. They are a type of device used for suppressing high-frequency signals in circuits and thus in reducing the disturbances in the circuit. EXC-24CB221U is a type of common mode choke, which is widely used in various applications such as power systems, power supplies, telecommunications, and optoelectronics. In this article, we will take a closer look at the application field and working principle of EXC-24CB221U.

Application Field

The EXC-24CB221U can be used in a variety of applications, such as:

• Power supplies and UPS systems
• Lighting systems
• Telecommunications
• Optoelectronics
• Automotive electronics
• Instrumentation

The EXC-24CB221U are designed to be robust and can provide stable performance in conditions like extreme temperatures and vibration. It features low leakage current, low self-resonance, and high current capability, making it suitable to use in power systems, telecommunications, and optoelectronics.

Working Principle

The EXC-24CB221U common mode choke uses two cables or wires to wrap around a core, which is usually made from an iron material. These two wires are linked together so that they can pick up the same signals, or otherwise known as ‘common mode signals’. As the signals travel through the choke, they become attenuated or reduced. This helps to reduce interference and noise in the circuit.

The working principle of the EXC-24CB221U is based on inductance. When a current passes through one of the two cables, the alternating magnetic field generated by this current interacts with the other wire, inducing a current. This current causes an opposing magnetic field that works to cancel out the original current, thus reducing the signals. This helps to suppress the common mode signals and reduce interference.

The EXC-24CB221U can be used with either a single-ended or differential mode topology. In single-ended mode, the common mode signal travels between the two wires in the same direction. In differential mode, the common mode signal travels between the two wires in opposite directions. The EXC-24CB221U can be used with either of these modes, depending on the application.

Conclusion

The EXC-24CB221U is a type of common mode choke, which is widely used in various applications such as power systems, power supplies, telecommunications, and optoelectronics. It features low leakage current, low self-resonance, and high current capabilities, making it suitable to use in power systems, telecommunications, and optoelectronics. Its working principle is based on inductance, as it blocks alternating magnetic fields that cause interference or noise in the circuit. The EXC-24CB221U can be used with either a single-ended or differential mode topology, depending on the application.
