Foreword YAGEO Group is a global leader in electronic components, uniting trusted brands like YAGEO, KEMET, Pulse, and Telemecanique. Our comprehensive portfolio includes capacitors, resistors, inductors, magnetics, RF, sensors, and circuit protection components that enable innovation across automotive, industrial, renewable energy, and computing markets. With a strong focus on quality, reliability, and application-driven design, we support engineers in solving complex challenges through advanced materials, robust technologies, and global support. This document highlights key trends and system requirements while showcasing how YAGEO Group's solutions help drive progress in next- generation electronic systems. A single leap does not define the transformation of the automotive industry; rather, it's the convergence of many innovations transforming how vehicles are built, powered, and experienced. From 48V architectures enabling smarter subsystems, to wide bandgap semiconductors unlocking new levels of power density and efficiency, to 800V electrified powertrains reshaping propulsion, we are witnessing a reinvention of the vehicle from the inside out. Enabling every fast switch, efficient conversion, and autonomous feature is a foundation of robust passive components. These components must now withstand higher temperatures, greater vibrations, faster switching frequencies, and increased voltages, while minimizing electrical parasitics, to deliver greater power efficiency and uncompromising reliability. At YAGEO Group, we see this moment as an inflection point where quality and reliability are no longer just product specifications but critical system enablers. We're engineering passive technologies not only for today's EVs, but for the challenges of tomorrow's mobility platforms: more electrified, more integrated, and more software-defined. This guide explores how passive components are evolving to meet the demands of electrification and how we're helping engineers to design confidently in the face of new voltage domains, shrinking design envelopes, and higher thermal profiles. The future of mobility begins with what is Built Into Tomorrow. By Claudio Lollini, Senior Executive Vice-President, YAGEO Group 5 Powering the New Automotive Era with Smart Passive Solutions
