Common Mode Chokes

Common mode chokes are typically designed using a variety of techniques. In this article, we will be discussing in detail a particular type known as the PCMF1USB30Z.

Application Field

The PCMF1USB30Z is primarily used to stop common mode noise from entering a system. This type of noise is especially problematic with high-speed data lines such as USB and HDMI connections. By using this type of choke, the noise can be filtered out before entering the system.

Additionally, The PCMF1USB30Z is designed to reduce the amount of both common mode and differential mode noise. This is done by using ferrite beads to help create a low-impedance path for the noise, and utilizing an electrolytic capacitor to help further reduce the noise. This makes the PCMF1USB30Z ideal for use in a wide variety of applications such as consumer electronics, industrial electronics, automotive electronics, and medical electronics.

Working Principle

The PCMF1USB30Z works by utilizing a combination of ferrite beads and capacitors. The ferrite beads serve to create a low-impedance path for the noise, which reduces the amount of noise that will reach the system. The capacitors are used to help further reduce the noise, by providing an additional path for the noise to travel along.

When the noise reaches the PCMF1USB30Z, it is stopped on three different levels: common mode noise, differential mode noise, and transverse mode noise. The common mode noise is stopped by the ferrite beads, the differential mode noise is stopped by the capacitors, and the transverse mode noise is stopped by the ferrite beads and capacitors working together.

The PCMF1USB30Z is designed to work with a variety of systems, and is capable of handling a range of signal frequencies. This makes it ideal for use in a variety of applications, and helps to ensure the system is protected from the damaging effects of common mode noise.
