Würth Elektronik’s webinar, “Safety by Design: X and Y Interference Suppression Capacitors for Power Line Filters,” focuses on the role of safety-certified capacitors in ensuring electromagnetic compatibility (EMC) and electrical safety in mains-connected systems. It explains how X and Y capacitors are used in power line filters to suppress conducted interference and protect equipment from electromagnetic disturbances. The session covers key international standards such as IEC 60384-14 and highlights their importance in designing compliant and reliable products. It also introduces the latest developments in capacitor technology, including new Y2 film capacitors and THB X2 capacitors, designed to meet modern performance and environmental requirements. In addition, the webinar provides practical guidance on selecting the appropriate capacitor types based on application needs, safety constraints, and regulatory compliance, helping engineers make informed design decisions.
