Common Mode Chokes are electronic components used to reduce noise or reduce electromagnetic emissions in electric devices. A common mode choke, such as B82721J2301N020, is designed to reduce or limit the amount of common mode noise on the signal lines running between two points. The common mode noise is caused by the high-frequency interference, which is generated by the power lines, wireless signals, and switching signals.Common mode chokes use the principle of inductance to reduce the interference from high-frequency signals. The common mode noise is characterized by its equal magnitude on both signal lines. The choke consists of an inductor, which acts like a coil and can store energy inductively within a magnetic field. As current flows through the inductor, the magnetic field generated by the inductor acts as a filter, blocking the high-frequency interference.Common mode chokes are used in a wide range of applications, such as motor control, telecom, automotive, and industrial applications. They are also used in consumer and mobile applications, such as smartphones, satellite receivers, TVs, and radios. Common mode chokes are also used in data and network communications, automotive engine controls, and robotic applications.Common mode chokes provide both common mode noise attenuation and differential mode noise attenuation. Differential mode noise is an interference generated when current flows through the two signal lines in the opposite direction. The differential mode noise can cause errors in the communication signals. The choke acts as a filter, blocking the differential mode noise and allowing only the desired signal to pass through. The common mode choke also helps in the prevention of electromagnetic interference (EMI) generated by the device.Common mode chokes are available in various sizes, shapes, and capabilities. They can be either embedded into PCBs or be an external component. They are also available in a wide range of package styles such as THR, SMD, and DO-214. The selection of the choke depends on the application and on the environment in which it will be used. The specifications of the choke depend on its intended application, frequency range, and inductance, as well as on environmental conditions.The B82721J2301N020 is a common mode choke designed to reduce common mode noise at the rated voltage of 13V. It is a surface mount package with a 0Ω impedance that can operate at frequencies up to 200MHz. The inductance of the choke is 0.6mH. The maximum DC current is 500mA, and the maximum AC current is 500mA. The package size is 5x12x6.75mm and the temperature range is -40 to +125℃.Common mode chokes are widely used in electronic designs as a filtering device. They are used to reduce high-frequency noise and eliminate differential mode noise. They provide an economical and efficient way to filter out unwanted noise, thereby improving the performance of the system. Common mode chokes are also used to reduce EMI emitted from the system, thus complying with the FCC regulations.
