Common Mode Chokes, often referred to as CM chokes, are, as the name suggests, devices that block currents and signals of a provided frequency range and support the use of cleaner power sources with improved signal quality in an array of applications. CM6560-225 is one such device manufactured by Bourns, a company widely renowned for its work in specialty components. A Common Mode Choke can be defined as a ferrite device utilized in electronic circuits to stop any common mode currents that could be induced in a power supply, to filter out noise from electronic devices, and to ensure good signal integrity. The main purposes of CM chokes are stated to be frequency-selective filter networks, EMI or RFI reduction, and common mode noise reduction. In the domain of power systems, for instance, CM chokes are deployed to reduce power disturbance and electromagnetic interference. It is crucial to use these chokes in extensive power systems in order to shield the electrical systems from externally generated electrical disturbances that can disrupt an entire operation as well as eliminate any power system oscillations. That way, the system performance as a whole is enhanced by increasing the operating life of the system.A CM6560-225 Choke manufactured by Bourns, as previously mentioned, is a high-frequency common mode inductor, designed for applications in LED lighting, AC/DC adapter, and switching power supply. It is a commercial temperature range part with a maximum DC resistance of 0.37 ohm and an inductance of 0.225 uH. It features an operating visible core temperature of up to one hundred seventy degrees Celsius, and it comes in the SMD (Surface Mounted Device) package. The working principle of the CM6560-225 is quite simple. It implements two winding coils that can share a common magnetic core, which usually comes in the form of a ferrite bead or tube, making the device an inductor. During operation, the highest level of common-mode noise is seen on the two winding coils. This noise creates a high level of harmonic oscillation on the equipment, leading to a non-linear operation. So, in order to eliminate this type of problem, CM chokes are used to filter out the harmonic oscillation which in turn helps the device to run at a linear phase operation. When it comes to application fields, the CM6560-225 specifically is utilized for LED lighting, AC/DC adapter, and switching power supply. The choke is capable of maintaining high current capability based on its wide operating temperature range. The choke is used for small size LED lighting devices which are often heavily loaded in nature and require robust components to keep up with the zero current switching conditions. It is also used in AC/DC adapter which requires a low operating temperature as well as low levels of interference. The CM chokes are utilized in switching power supply devices because they help to reduce the ripple of power sources in harsh working conditions. In conclusion, CM chokes in general are extensively used devices in a wide array of applications and the CM6560-225 model specifically is a high-frequency common mode inductor with a wide operating visible temperature range and low DC resistance. It is used in operations such as LED lighting, AC/DC adapter, and switching power supply to reduce harmonic oscillation and noise, while also improving signal integrity and reliability.
