What the AEC-Q200 rating means for your BOM
This TAJB107K006TNJ carries AEC-Q200 qualification — the automotive passive-component stress standard.
Capacitance, voltage, and ESR — the decoupling fit
Rated 100 µF at 6.3 V with ±10% tolerance — this is a bulk decoupling capacitor for a 3.3 V or 5 V rail where the voltage derating rule (typically 50-80% of rated voltage) still leaves margin.
Temperature range and lifetime profile
Operating from -55 to 125 °C, this capacitor covers the full military-temperature band. The lifetime rating is 2000 hours at 125 °C — a standard endurance test for tantalum chips. In an engine-bay ECU that sees 105 °C ambient, the actual service life extends well beyond the 2000-hour figure because the average temperature is lower. The molded construction keeps the terminations sealed against moisture ingress during reflow and field exposure.
Package and footprint for pick-and-place
The 1411 (3528 Metric) case — 3.50 mm x 2.80 mm body, 2.10 mm seated height — is a standard tantalum chip footprint. The B-size code matches the industry-standard pad layout for this capacitance range. Supplied on tape and reel (cut tape also available), it runs through a standard reflow profile without special handling.
