Common Mode Chokes are widely used in many applications to provide signal and power isolation, offer input protection for downstream equipment, and provide EMI/RFI noise filtering. EXC-14CE650U is an example of a common mode choke that is regularly used in industrial and commercial power applications. This article will explain the application fields for this product and the working principle behind the product.

Application Field

EXC-CE650U common mode chokes are mainly designed for high-voltage and medium-current applications in the high-frequency area. It exhibits better performance than existing single-phase filters in many application fields, such as industrial automation, inverter and switching power supplies, aircraft auto-control systems, communication and network equipment, and power-driven controllers.

Working Principle

EXC-CE650U common mode chokes are composed of a toroidal core, two sets of symmetrically wound common mode inductors, and an encapsulated coil. The toroidal ferrite core concentrates the flux generated by the current passing through the inductors, to provide enhanced inductance in the common mode circuit. In addition, the encapsulated design of the coil prevents external hazards from causing any damage to the components.

The choke works by reducing the differential-mode interference while balancing the current flowing through the two windings of the inductors. The differential-mode interference is reduced due to the inductor’s magnetic field, which restricts the current from changing rapidly. The balanced current magnitude helps cancel out the magnetic flux which is generated when current flows through the two windings, thereby suppressing common-mode interference.

The performance of EXC-CE650U common mode chokes is further enhanced by a number of features, such as their low-resistance, low-inductance, and wide bandwidth. This ensures that these chokes are able to handle high-frequency signals even under heavy load, and that they are able to withstand extreme current and temperature conditions.

Conclusion

EXC-CE650U common mode chokes are designed to provide reliable and high-quality signal and power isolation in medium- to high-voltage and high-frequency applications. They feature enhanced inductance, low-resistance, low-inductance, and wide bandwidth, as well as an encapsulated coil design that protects the core from environmental hazards. The combination of these features makes these common mode chokes an excellent choice for a variety of power and signal isolation applications.
