High-Capacitance MLCCs for Autonomous Driving and ADAS Evolution 3225 / 220µF / 4V

Automotive-Grade
X7T
AEC-Q200

Factors Driving 220μF MLCC Adoption

Increasing Capacitance Demand around ICs

Higher-performance AD/ADAS ICs require more MLCCs and higher ca pacitance

Severe PCB Space Constraints

ECU integration and miniaturization further limit board space

High Reliability
Requirements

Automotive grade（AEC-Q200）, reflow stability, and long lifetime required

Polymer Capacitor Replacement

MLCCs enable downsizing with low ESR and low ESL

Polymer Capacitor Replacement Leveraging MLCC Advantages

Trend: Replacement from polymer capacitors to MLCCs is accelerating alongside higher SoC performance

From left to right: progression of higher performance and miniaturization of equipment.Left: AD Lv2 ECU (297×210 mm) — circuit includes polymer capacitors to secure capacitance.Center: AD Lv2+/3 ECU (152×152 mm) — replacement of polymer capacitors with high‑capacitance MLCCs is advancing.Right: AD+Cockpit ECU (152×152 mm) — MLCC replacement is further accelerating.
