Common Mode Chokes serve a variety of applications in various electrical and electronic fields. In this article, we will discuss the application field and working principle of TF2720B-402Y4R0-01, one particular type of Common Mode Choke.

Introduction

Common Mode Chokes (CMCs) are a type of electromagnetic component used in a wide variety of industries, including automotive, industrial, and consumer electronics. CMCs act as a filter to reduce the amount of electromagnetic interference (EMI) emitted from the device or circuit they are installed in. CMCs are commonly seen in applications such as power supplies, motor controls, motor drives, and audio-video equipment.Specifically, TF2720B-402Y4R0-01 is a common mode choke designed for use in industrial DC/DC converters, motor control systems, and AC/DC switch mode power supplies. It is a medium-power device with an inductance value of 13.89mH, a DCR (DC Resistance) of 1.93 ohms, and a temperature range of -40°C to +75°C. It is rated to withstand up to 0.3Amps of current, with a maximum operating voltage of 1.28V.

Application Field

TF2720B-402Y4R0-01 is most commonly used in motor control devices, power supplies, and other potential noise generating applications. Common mode chokes can help attenuate EMI in switching power supplies and DC/DC converters, as well as reduce noise folded back into the power supply by the load.In industrial applications, it is important to reduce the amount of EMI present in a system, as it can interfere with other electrical devices or components. By installing a TF2720B-402Y4R0-01 common mode choke, interference issues in electrical systems can be effectively reduced or eliminated. The choke can also be used to reduce the amount of radiated noise from the system, which is useful in environments where EMI must be kept to a minimum.

Working Principle

TF2720B-402Y4R0-01 works on the concept of common-mode noise rejection. This noise is generated as a result of currents flowing through both the live and return paths of the circuit. The common-mode choke is able to reduce this noise by diverting the unwanted current away from the sensitive components. The core of the common mode choke is made up of several windings of copper wire. When current passes through the windings, a magnetic field is generated. This magnetic field interacts with the current flowing in the circuit, which creates an opposing magnetic field and a resultant opposing voltage. This opposing voltage opposes the common-mode noise, resulting in a reduction of the noise and improved performance of the system.

Conclusion

The TF2720B-402Y4R0-01 common mode choke is a medium to high-power device designed for use in industrial applications. It is able to reduce the amount of common mode noise generated in the system, allowing for improved system performance. The choke is an effective tool for reducing EMI in DC/DC and AC/DC converters, motor control systems, and other potential noise generating applications.
