Common Mode Choke Inductance: Noise Suppression and EMC Compliance

There are several benefits to the common mode choke inductance that stem from its design and function. Firstly, it effectively filters out common mode noise which can cause data corruption and equipment malfunction. This in turn results in better signal quality from equipment, less frequent failures and lower built-in redundancy requirements for instance when such computers are used on an airliner to monitor engines or anywhere else that reliability is most important at least as a secondary consideration (and especially since break-points tend not trigger until the job is done). Secondly, it helps devices comply with EMC standards, which means they cannot emit excessive noise that might interfere with other devices. Thirdly, it gives protection from external sources of noise, such as electrical storms or nearby electronic equipment that might interfere with the normal functioning of the device. Fourthly, the common mode choke inductance is compact, cost-effective, and easy to implement into existing and new design (making it a perfect solution for noise suppression in a variety of systems).
