Common Mode Chokes

A common mode choke is an electrical component used to reduce common mode noise in electronic signals. It does this by preventing the transfer of common mode signals, which are DC signals that run in both directions on a signal line. Common mode chokes are typically constructed by winding two or more adjacent wire coils around a magnetically conductive core.

The common mode choke known as the SC-02-10G is a miniature wire-wound common mode inductor designed for use in automobiles. This type of common mode choke is used to reduce and attenuate the electrical noise and interference generated as a result of power surges, fluctuations, and the usage of high-powered equipment. It is most commonly used in the electrical systems of vehicles to provide EMC (electromagnetic compatibility) and reduce the levels of radiated and conducted electromagnetic noise.

SC-02-10G Application Field and Working Principle

The SC-02-10G common mode choke has an operating temperature range of -55°C to +125°C, and features a wide range of inductance values from 3.3μH to 100μH. It is housed in a small shielded package which provides excellent ESD and EMI shielding performance. This common mode choke is designed for use in a variety of automotive applications, and may be used to reduce common mode noise in electrical systems that utilize CAN BUS, CCD, and other data communication lines.

The working principle of the SC-02-10G common mode choke relies on the idea of inductive reactance. When a current is passed through the two wire coils, an electromagnetic field is generated. This field has a higher inductance than that of a single wire coil, and hence produces a higher reactance against an AC signal. This reactance is what ultimately causes the common mode signal to be blocked from being passed through the signal line, thus reducing the amount of noise present in the signal.

In addition to its use in automotive applications, the SC-02-10G common mode choke is also suitable for use in other high-power equipment, such as antennas, power supplies, and computers. Additionally, it can be used to protect digital signals against static electricity in certain situations.

Conclusion

The SC-02-10G common mode choke is a miniature wire-wound common mode inductor designed for use in automobiles and other high-power equipment. It serves to reduce and attenuate the electrical noise and interference generated as a result of power surges, fluctuations, and the usage of high-powered equipment. Its working principle relies on the idea of inductive reactance to reduce the amount of common mode noise present in a signal line.

This common mode choke is designed for use in a variety of automotive applications and other applications involving high-powered equipment. Its small, shielded package allows it to provide excellent ESD and EMI shielding performance, making it suitable for a number of different applications.
