GRT21BC81A106KE01L CAP CER 10UF 10V X6S 0805
The GRT21BC81A106KE01L is an automotive AEC-Q200 qualified multilayer ceramic capacitor (MLCC) from Murata, housed in a 0805 (2012 metric) SMD package. It features 10µF capacitance, 32V rated voltage, X6S dielectric characteristic, and ±10% capacitance tolerance, delivering ultra-stable electrical performance under harsh automotive electrical and thermal conditions, making it a certified high-reliability bulk decoupling solution for 12V automotive powertrain, safety, and high-temperature in-vehicle systems.
Key Features and Highlights
● Full AEC-Q200 Automotive Qualification: Strictly certified to AEC-Q200 automotive component reliability standards, supporting operation across -55°C to +125°C ambient temperature for in-vehicle harsh environment deployment.
● Stable X6S Dielectric Performance: Maintains ±22% maximum capacitance variation across full temperature and rated voltage range, far outperforming general-purpose X7R MLCCs under high bias voltage and high temperature conditions.
● High Rated Voltage Margin: 32V rated voltage provides sufficient safety margin for 12V automotive battery systems, easily handling load dump voltage transients without capacitance collapse or breakdown risk.
● Low ESR and High Ripple Current Rating: Optimized internal electrode structure delivers ultra-low equivalent series resistance at 100kHz, supporting high ripple current handling for automotive motor drive and ECU power filtering.
Frequently Asked Questions (FAQ)
Q: Why is X6S dielectric preferred over X7R for automotive safety-related systems?
A: X6S delivers far better capacitance retention under DC bias and high temperature conditions, ensuring the decoupling capacitance value remains stable even under real worst-case automotive operating conditions.
