C h a p t e r 4 | P u s h i n g Pa s s i v e s t o t h e L i m i t Naturally, any failure in these areas can compromise functional safety. Capacitors must, therefore, withstand surge voltages and transient events without breaking down. Inductors must not saturate during regenerative braking or during fault conditions. Resistors used for current sensing must maintain values across temperature ranges and over the entire vehicle lifespan to support diagnostic and safety logic. Furthermore, the implications of these reliability requirements become a matter of system integration. As vehicles adopt more centralized or zonal architectures, the physical distance between control modules and sensors is increasing and places added demands on signal integrity and EMI suppression, both of which fall to the passives in the design. Components that once operated in quiet local environments must now maintain clean signal paths across longer distances and more complex wiring harnesses, without adding noise, reflection, or loss. YAGEO guarantees automotive component reliability by • Designing components that exceed AEC-Q200 with enhanced resistance to thermal cycling, humidity exposure, and long-term mechanical vibration; • Offering inductors and capacitors validated under OEM-specific shaker tests and thermal shock profiles; • Actively participating in the evolution of automotive qualification standards and supporting OEMs with modeling tools, reliability data, and collaborative design feedback; and • Providing flexible-termination MLCCs, anti-surge resistors, and metal-composite inductors engineered for stability across extreme stress conditions. AEC-Q200 is just the baseline. These components must also withstand higher temperatures, greater thermal shock, and increased humidity. We have to go well beyond the standard requirements."
