<p>Common Mode Chokes, or CMCs, are electromagnetic induction components that can help to control high frequency electromagnetic interference (EMI) and electrostatic discharge (ESD). EXC-14CH120U is a type of common mode choke which is also known as an EMI/RFI filter, an inductor coil, or a ferrite bead. </p><p> EXC-14CH120U consists of two windings that are wound onto a ferrite core. These two windings are connected in series to form a single electrical circuit. The choke\'s job is to block the unwanted current and attenuate the unwanted signal. It also helps to increase the common mode impedance of a given circuit, thereby ensuring better signal integrity. </p><p>EXC-14CH120U is designed specifically for use in applications where high frequency noise needs to be controlled and prevented from entering the circuit. It is mainly used to reduce the impact of EMI/RFI noise from entering the circuit. The EXC-14CH120U can also be used to reduce common-mode noise which is caused by an imbalance between the two signal wires of a differential signal. </p><p>EXC-14CH120U\'s working principle is based on the concept of electromagnetic induction. When an alternating current (AC) or a signal passes through its windings, a magnetic field is generated around the windings. This, in turn, induces a reverse current in the opposing winding which is known as counter EMF. This counter EMF acts to oppose the original current and attenuate the signal. </p><p>The EXC-14CH120U is mainly used in a variety of industrial and medical applications such as power supplies, motor drives, circuit boards, and other communications systems. It is also used to suppress EMI from entering a printed circuit board (PCB) or any other relevant electronics components. For example, the EXC-14CH120U can be used to reduce EMI from entering the circuit board, thereby preventing any damaging or interfering signals from entering the system and causing damage. </p><p>In addition, the EXC-14CH120U can also be used to reduce ESD in communication systems. ESD can occur due to an imbalance between the positive and negative voltages in the system. The EXC-14CH120U will help to reduce the imbalance by suppressing the ESD voltage and thus reduce the chances of damages due to ESD. </p><p>In conclusion, the EXC-14CH120U is a type of common mode choke which is designed to help reduce high frequency noise and also help reduce EMI and ESD which can cause damage to the circuit. It is used in a variety of applications, from power supplies to motor drives and circuit boards.</p>
