In new energy vehicles, MLCC is widely used in battery management system (BMS), advanced driving assistance system (ADAS), motor control unit, on-board infotainment and other core scenarios. Different from consumer electronic products, the failure of automotive electronic components may directly affect driving safety, which makes the reliability requirement of automotive grade MLCC far higher than that of any other civil MLCC products.
According to the industry standard, automotive grade MLCC must pass the AEC-Q200 strict certification, which means it can operate stably in the extreme temperature range of -55℃ to 175℃ for a long time, and can withstand the impact of severe vibration, high humidity and harsh electromagnetic environment during driving. Any unqualified ordinary MLCC used in automotive scenarios may bring huge hidden dangers to vehicle safety.
Many purchasers who are new to the automotive electronics industry cannot accurately distinguish the difference between automotive grade MLCC and ordinary industrial MLCC, which leads to wrong material selection. The two have essential differences in the following three aspects:
Comparison Dimension | Ordinary MLCC | Automotive Grade MLCC |
|---|---|---|
Maximum Operating Temperature | Usually 85℃-105℃ | Stable operation at 125℃-150℃, some models support 175℃ |
Failure Rate Standard | 1% level per thousand hours | Close to zero failure rate, meet the zero-defect requirement of automotive industry |
Production Process Control | Conventional quality inspection | Full process traceability, 100% high and low temperature screening, strict internal crack detection |
Application Scenarios | Consumer electronics, ordinary industrial equipment | xEV, ADAS, autonomous driving, on-board power system |
At present, BarronMLCC's full series of automotive grade MLCC products have passed AEC-Q200 certification, covering the full range of specifications required by new energy vehicles, from low-voltage signal processing to 2000V high-voltage power system. We have established supporting cooperation with many new energy vehicle manufacturers and automotive tier 1 suppliers at home and abroad. For overseas automotive electronics purchasers, we can provide complete certification documents, long-term reliability test reports and PPAP level sample services, helping you quickly complete the component introduction and qualification verification.
At present, the global automotive grade MLCC market is still in a state of tight supply, and many overseas buyers are facing the problem of long-term shortage of Japanese and Korean brands. BarronMLCC, with its stable domestic production capacity and perfect inventory system, can provide you with a more cost-effective and faster delivery alternative supply solution, helping your new energy vehicle projects to be launched on schedule.
