Introduction to Common Mode Chokes

Common mode chokes (CM chokes) are components that are designed to reduce the amount of common noise that is found in signaling and power supply applications. This type of choke is used to prevent interference from one application area from travelling to another in the form of energy. This is accomplished by having two current paths that are isolated from each other, thus blocking the flow of common mode noise.

CM2021Y330R-10 Application Field and Working Principle

The CM2021Y330R-10 is a common mode choke manufactured by Yageo. It is designed for use in power, signal, and communication lines that require minimal noise reduction. The indicator provides small size, low cost, wide operating temperature range, and high inductance value. It has a maximum current of 5 A and can withstand a maximum voltage of 200 V. It has an input impedance of 330 Ω at a frequency of 20 MHz.The working principle of the CM2021Y330R-10 is based on the choke\'s inductive property. It acts as an inductor, where a magnetic field is generated when current passes through it. This magnetic field creates opposing force on the current, resulting in a decrease in the overall current. Since the current is reduced, the associated noise is reduced as well. This is how CM chokes provide noise reduction in applications.In addition, the CM2021Y330R-10 also features a high number of windings, which increases the inductance value of the choke and thus providing an even more effective noise reduction.

Conclusion

Common mode chokes are highly effective components that can be used to reduce noise in a variety of power, signal and communication lines. The CM2021Y330R-10 is a common mode choke manufactured by Yageo with a high level of inductance and a maximum current of 5 A, as well as a wide operating temperature range. It has a high impedance of 330 Ω at 20 MHz and uses its inductive property to reduce the amount of noise present in an application. When combined with its high number of windings, the CM2021Y330R-10 provides an even more effective noise reduction solution.
