ADAS SoCの高性能化に伴う小型高容量MLCCの提案

運転者の安全性や利便性を支援するため、ADAS（Advanced Driver Assistance System）技術は進化し続けています。これに伴い、カメラ、ライダー（Lidar）、レーダー（Rader）などのようなセンサーからより多くの情報を収集・分析するためにADAS SoC（System on Chip）の性能も向上している傾向があります。  
SoCの高性能化は消費電力の増加およびSwitching Frequencyの上昇をもたらし、SoCへの安定した電力供給のため、高容量・低ESL MLCCが求められています。

一番目のソリューション、小型高容量MLCC   

ADAS技術の発展に伴い、SoCの性能は約10倍、Lv3の消費電力は約6倍以上増加すると予測されています。安定したADAS SoCの動作を実現するように、より多くの高容量MLCC、そして限られたPCBスペースでの実装のため、小型のMLCC仕様が求められます。
