Q.Please explain why capacitors are used as noise suppression components. Capacitors >  Ceramic Capacitors >  Multilayer Ceramic Chip Capacitors A. Capacitors interrupt direct current and let alternating current pass. For electronic devices that run on DC voltage, elements of an alternating-current become noise that makes operation unstable. As a countermeasure, capacitors are connected so as to allow the AC elements to pass through to the ground. The electronic device operates properly because only the necessary DC components are supplied. Unnecessary signals (noise) are removed and necessary signals remain. >>Multilayer Ceramic Chip Capacitors Product site For any other product-related questions or inquiries, please contact us throughone of our sales representatives or this website.
