Q: What is RTC crystal?

A: AEC-Q200 is a reliability standard for passive electronic components developed by the Automotive Electronics Council. It defines a series of qualification requirements for components used in demanding automotive environments, including conditions involving temperature, humidity, mechanical shock, and vibration. SJK automotive-grade crystals have passed AEC-Q200 certification and are designed to meet the reliability requirements of vehicle electronic systems.

The qualification process includes strict reliability testing.

Temperature cycling is conducted from -50°C to +150°C for 1,000 cycles to verify that the package remains free from cracks, leakage, and structural damage.

Mechanical shock and vibration testing simulates harsh driving and road-impact conditions.
Humidity and heat testing is conducted at 85% humidity and +85°C for 1,000 hours to evaluate electrical performance stability.
Hermeticity, lifetime, and other reliability tests are also included in the qualification process.

For customers evaluating frequency components for automotive electronics, AEC-Q200 is therefore an important qualification to consider when assessing component reliability and suitability for demanding vehicle environments.
