A common mode choke is an inductor used in radio frequency circuits. It is designed to reduce the amount of undesired sign waves in a circuit, such as common mode noise. The EXC-34CE670U is one type of common mode choke used in a variety of applications. By understanding its application field and working principle, its efficiency and accuracy can be further improved.

Application Field of EXC-34CE670U

The EXC-34CE670U is a common mode choke, designed and manufactured by Coilcraft, Inc. It’s mainly used in power supply circuits, switching regulator circuits, high frequency circuits, and so on. It\'s mainly used as a filter component, and can shield signals from unnecessary interferences. This type of choke is offers high signal-to-noise radio and immunity to frequency drift.

Working Principle of EXC-34CE670U

The EXC-34CE670U works by eliminating common mode noise in a circuit. The choke is composed of two inductors, each with an inductance of 1 um. The inductors are wound in the same direction and phase, so that the signals generated by the coil are all in phase. This ensures that the signal only passes through one inductor, and the other inductor is purposely left idle. The two inductors have high impedance, which isolates the circuit from any kind of interference.

The choke works by blocking signals from “unwanted sources ”, so that only the desired signals pass through. It also works as a low-pass filter, allowing only signals below a certain frequency to pass through. The choke is also capable of suppressing transients, which can damage sensitive electronic components in the circuit.

Advantages of using EXC-34CE670U

Using the EXC-34CE670U has a few significant advantages. Firstly, it is extremely robust and highly reliable. It is designed to work efficiently in harsh environments, so it is suitable for use in industrial applications. Secondly, the choke is highly efficient, and it can shield signals from a range of RF frequencies. Thirdly, the choke is inexpensive compared to other common mode chokes of the same specification. Finally, the choke has a wide working temperature range, so it can be used in a variety of different environments.

Conclusion

The EXC-34CE670U is a common mode choke designed and manufactured by Coilcraft, Inc. It is widely used in power supply circuits, switching regulator circuits, high frequency circuits and many other applications. The choke works by eliminating common mode noise in a circuit, and is capable of blocking signals from “unwanted sources ”, and suppressing transients. It is highly efficient, reliable, and cost-effective, and can be used in a variety of different environments.
