Common Mode Chokes are electrical filters designed to stop common mode interference on a circuit. B82522VC5 is an example Common Mode Choke mainly used in applications for signal integrity. The following article outlines the application field and working principle of B82522VC5.

Application Field

B82522VC5 has been widely used in common mode suppression, EMI/RFI suppression, signal line conditioning, and grounding. It is mostly used in signal integrity applications such as USB, Ethernet, HDMI, DVI, and CATV applications. It is a low-profile and low-cost alternative to the traditional larger chokes.

The B82522VC5 can be used to suppress signal and common mode voltages in both balanced and unbalanced pairs. This makes it suitable for most circuit types. The B82522VC5 has a center tap conductor, which allows it to work in high density installations. The center tap conductor helps to evenly suppress interference that is common in a densely populated environment.

Working Principle:

The B82522VC5 works through an inductive principle. The artificial inductor, also known as a common mode choke, is a passive electronic component made up of a combination of an inductor and resistor. The inductor is connected to two pins in the center of the choke on one side of the circuit and acts as a small transformer. The inductor and resistor combination creates a filter that filters out unwanted noise in the signal. The resistor portion helps keep the current at an acceptable level. As high frequency noise passes through the inductor, it causes an oscillation of the magnetic field which dampens the signal and thus reduces the interference.

The B82522VC5 is designed with one additional feature. The center tap conductor allows the user to evenly distribute the field of the choke, thereby increasing its suppression effects. The tap conductor is located in the middle of the device and helps to create a neutralizing field around the entire B82522VC5. This helps to reduce the noise generated by the inductor and thus increases the effectiveness of the device.

Conclusion:

The B82522VC5 is a low-profile and low-cost alternative for signal integrity applications. It has the capability to suppress signal and common mode voltages in both balanced and unbalanced pairs providing an effective solution for most circuit types. In addition, the center tap conductor helps to create a neutralizing field around the entire B82522VC5, increasing its noise suppression capabilities.
