An Update on High Temperature Passive Electronic Components and Emerging AEC Q200 Temperatures

The Automotive Industry drives many innovations for electronics and uses state-of-the-art devices. From electronification to V2X communications to sensors and high speed processing these modules require increasing environmental requirements from the Automotive Electronics Council. Passive electronic components like capacitors and multilayer varistors that perform decoupling, filtering, and circuit protection functions enable ECU and IC capability. But these passives can limit full capability if they do not keep up with high temperature requirements while maintaining electrical performance. In addition to high temperature material and product advancements on active and semiconductor devices, an update on high temperature passive components is worthwhile. The focus will be on capacitors where material set and capacitance are largely impacted by operating temperature. High temperature advancements will also be discussed for circuit protection devices that must perform reliably and repeatedly in austere transient environments.
