Common Mode Chokes (CMCs) are an important component for noise suppression in electrical systems. The PCMF3USB3B/CZ is a common mode choke filter designed for use in USB 3.0 applications. It helps ensure low-noise operation by suppressing EMI and reducing high-frequency voltage levels while maintaining complete signal integrity.

The PCMF3USB3B/CZ is ideal for USB 3.0 applications, where the signal data transfers at an incredible speed of 5 Gbps. It utilizes a three-line USB 3.0 connection with four terminals (or contacts), two for the differential (signal) lines and one for the common-mode line and ground. The combination of common-mode and differential-mode filtration helps to ensure optimal EMI suppression performance.

The PCMF3USB3B/CZ has been designed with a magnetic field that is created by energizing the windings with a constant current. The magnetic core is designed with two closed magnetic circuits: one for the differential-mode and one for the common-mode filters. The common-mode circuit consists of two Faraday shields, which create a tight screening effect. The Faraday shields also provide a uniform magnetic field that efficiently captures and suppresses common-mode interference.

The differential-mode circuit of the PCMF3USB3B/CZ is composed of two inductors that reject common-mode noise from two opposing directions. As the differential-mode signal passes through an inductor, its energy is absorbed by the ferrite core. This creates a low-frequency electrical opposition to the incoming signal that allows only the desired signal to pass through. The inductors also act as a low-pass filter and reduce high-frequency noise.

The PCMF3USB3B/CZ features a variety of methods for EMI shielding, including filtered feed-throughs, pin-and-socket EMI gaskets, shielded cables and enclosed shielding cages. These methods provide superior protection against EMI interference and help to prevent data loss due to excessive noise. The PCMF3USB3B/CZ also features an LED indicator that signals when the device is functioning correctly.

The PCMF3USB3B/CZ is an ideal choice for providing superior EMI protection in USB 3.0 applications. It combines common-mode and differential-mode filtration with various methods of EMI shielding to ensure optimum performance in noise-prone environments. Its small size and low profile allows easy installation and helps to save on space and material costs. The LED indicator helps to quickly and easily confirm that the device is functioning correctly.
