# Ceramic Capacitors [closed]

What is the difference between General purpose and Automotive grade ceramic capacitors, if they have the same capacitance, temperature coefficient and operating temperature. is there a manufacturing or design difference or are they the same except the Automotive ones go through additional screening?

• One is twice as expensive. Easier if you give two datasheets to compare, otherwise we don't know which ones you are looking at. – pipe Sep 20 '17 at 21:07
• Since most of the automotive grade ones should be AEC-Q200 compliant, there should be a design or manufacturing difference. These differences should lead to some differences in terms of characteristics (e.g. Z/ESR vs Frequency). There are also "Flexible MLCC"s (Google it). They are widely used in automotive. – Rohat Kılıç Sep 20 '17 at 21:09
• I believe automotive grades have better gas mileage ;) j/k but they have higher standards for quality factors like traceability etc. Considering the cost of failures and lawsuits, and fact that caps with ripple current or voltage stress are top failure components, I’d choose reliable parts, design and process as my motto anyday over the dirt cheapest parts – Sunnyskyguy EE75 Sep 20 '17 at 21:23
