Common Mode Chokes

A common mode choke, also known as a differential mode choke, is an electronic component that blocks or suppresses electrical noise on the line. It is a type of inductor consisting of two sets of coils wound around a core of ferrite or other materials. Common mode chokes can filter out electromagnetic interference such as radio frequency interference (RFI) or electromagnetic interference (EMI) from the power line. Additionally, they can also suppress the action of brushes that generate electrical sparks from motors. The common mode choke is a vital component in high-efficiency electrical motor systems.

The TF3435VU-500Y10R0-1H common mode choke is designed for a nominal DC current rating of 50 amperes and is designed for high frequency noise suppression in multiplexed power line systems. This product has many features that make it well-suited for applications such as current sensors, electric vehicle drive systems, and renewable energy systems. It has a maximum 30µH DC inductance and a maximum DC current rating of 60 amperes. The device is made of a ferrite material and comes in a convenient TO220 package for easy mounting.

Application Field and Working Principle

Common mode chokes are used in a wide variety of application fields, from the consumer electronics and computer sectors to industrial machinery and automobiles. In consumer electronics, common mode chokes are used to suppress EMI and RFI interference from modems, routers, and wireless LANs. In industrial machinery, they are used to filter out unwanted EM signals and to reduce noise in power systems. In automated vehicles, they are used to reduce electrical sparks generated by DC motors.

The TF3435VU-500Y10R0-1H common mode choke utilizes two sets of coils with differing inductances wound on a core material to form a fourier series of signals at EMI/RFI frequencies. The two coils are connected in series, creating an inductance of 30µH at DC current, which is able to suppress EM and RF interference. The device also utilizes a high DC current rating of 60 amperes, making it suitable for use in high-efficiency electrical motor systems.

In addition, the TF3435VU-500Y10R0-1H is designed to be highly resistant to thermal shock, making it suitable for use in high-temperature environments. The device is also designed to have a long mean time between failures (MTBF) of 500 years, proving its high reliability.

Conclusion

Common mode chokes are essential components in various types of applications, such as consumer electronics, industrial machinery, and automated vehicles. The TF3435VU-500Y10R0-1H common mode choke is a high-quality device designed for high efficiency, long MTBF, and excellent temperature resistance. By utilizing two sets of coils with differing inductances, the common mode choke is able to remove EMI/RFI interference from the power line, making it a vital component in high-efficiency motor systems.
