FAQs
1. Is this capacitor AEC-Q200 qualified?
No. For automotive applications, consider KYOCERA AVX’s AEC-Q200 certified series.
2. What is the shelf life?
Typically 12 months when stored below 30°C/60% RH per JEDEC standards.
3. Can it handle surge currents?
Yes, but use current-limiting resistors per manufacturer guidelines to avoid degradation.
4. Is it RoHS compliant?
Yes, compliant with Directive 2011/65/EU.
5. What’s the recommended reflow profile?
Follow IPC/JEDEC J-STD-020 for Pb-free processing (peak temp: 260°C).
Future Trends
KYOCERA AVX is developing next-gen tantalum capacitors with higher CV/g ratios and lower ESR for 5G and IoT devices. The TBJ series will likely see derivatives with improved thermal stability.
