Common Mode Chokes (CMC) are components used to deliver a variety of impedance levels for electromagnetic interference (EMI) and Electromagnetic Compatibility (EMC) applications. Among these components, the CM7560-125 is developed primarily for EMI suppression applications that require an operating temperature range of -40°C to 125°C. Motors, transformers, power systems, and other industrial devices can benefit from using CM7560-125 due to its reliable and low-cost design.

The CM7560-125 is a three-core toroidal common mode choke featuring low-Estopping power, low magnetic sensitivity, high impedance, high-frequency-sided shielding and leakage-resistive insulation constructor. The CM7560-125 can suppress EMI-induced noise by successfully obviating high-frequency current in a power system and preventing it from spreading further to other circuits. As a result, the reliability of the power system is increased.

The CM7560-125 features a robust design consisting of two windings in special high-speed insulation material that provides excellent insulation capability, a stainless steel shell for mechanical protection, and a ferrite core for electromagnetic interference. The dimensions of this component are 60mm in diameter and 25mm in height.

The application fields of the CM7560-125 include power systems, automotive, elevators, consumer electronics, and industrial control, among other technologies. Specifically, the CM7560-125 can be used in power converters, solar inverters, motor drives, UPS systems, switch power supplies, and other applications. Furthermore, it can be used to reduce the common-mode current along long cable runs, mitigating radiated noise injected to the power or signal lines.

The operating principle of the CM7560-125 is simple yet effective. When a high-frequency signal passes through the coil, vertically bridged high inductive coupled pins absorb the noise energy and convert it to heat. The ferrite core increases the inductance of the coil, allowing the choke to absorb more power. Furthermore, the CM7560-125 features a series of metal screens around the core, creating an electro-shielded environment and reducing the radiative noise.

The CM7560-125 is an effective tool used to reduce EMI and enhance EMC. Its low cost, robust design, excellent insulation capability, and high-frequency-sided shielding make it an ideal choice for a variety of applications. In addition, the CM7560-125 is designed to operate reliably at temperatures ranging from -40°C to 125°C, ensuring durability in challenging environments. Thus, this component is a viable and cost-effective solution for controlling EMI and providing excellent EMC.
