Common Mode Chokes

Common mode chokes are passive electrical components used in a circuit to reduce the amount of common mode noise that can occur in current paths. It does this by blocking the alternating current of the noise while allowing the other current to pass. The 7512-RC series of common mode chokes is the latest in ferrite-based filtering technology, with a wide range of applications and operating principles.

Applications of the 7512-RC Series

The 7512-RC series common mode chokes are designed to reduce the electromagnetic interference (EMI) of switching power supplies, motor control noise, and the like. It is also used as a noise reduction filter in various electrical systems. In addition, it has many applications in the consumer electronics, automotive, and telecommunications industries. It can be used to reduce electromagnetic radiation from automobile engines, computer monitors, and other devices. The 7512-RC series of common mode chokes is particularly suitable for applications with high AC ripple current, such as switching power supplies. It can also be used for reducing electromagnetic interference in communications, and to reduce noise in audio systems. In addition, these common mode chokes are a good choice for applications such as UL-certified systems, where high peak currents and low passband losses are desired.

Working Principle of the 7512-RC Series

The 7512-RC series of common mode chokes operates in a similar way to normal inductors. The inductor blocks the alternating current of the noise and allows the other current to pass. This eliminates the common mode noise by creating a strong magnetic field, which consists of both the static and the alternating parts of the current flow. When an alternating current is applied to a common mode choke, two equal-amplitude and opposed-phase magnetic fields are created. This reduces the common mode noise and allows a higher DC isolation voltage. The 7512-RC series of common mode chokes are designed to work efficiently even in high frequency applications, and able to reduce the EMI noise of motors, switching power supplies and other noisy applications.

Conclusion

The 7512-RC series of common mode chokes is a great solution for reducing common mode noise. It is suitable for a variety of voltage levels, and can be used in a variety of applications. The common mode choke works by creating two equal-amplitude and opposed-phase magnetic fields, which reduces the common mode noise and allows a higher DC isolation voltage. It is a great choice for applications such as motor control noise, UL-certified systems, and any other project that requires noise reduction.
