Automotive electronics growth (ADAS, infotainment)
The T55 series addresses these needs with its high volumetric efficiency and AEC-Q200 compliance potential.
| Model | Capacitance | Voltage | ESR | Size |
|---|---|---|---|---|
| T55V336M016C0070 | 33µF | 16V | 70mΩ | 7343 |
| KEMET T530B337M016ATE070 | 33µF | 16V | 70mΩ | 7343 |
| AVX TPSD337K016R0100 | 33µF | 16V | 100mΩ | 7343 |
Why choose T55V336M016C0070? Vishay's proprietary polymer formulation delivers lower ESR at high frequencies compared to competing 7343-case alternatives.
Voltage Derating: Operate ≤80% of rated voltage (12.8V for 16V part)
Thermal Management: Ensure PCB thermal vias for high ripple current
Placement: Position close to IC power pins for optimal decoupling
Polymer cathodes eliminate the "wear-out" mechanism of MnO₂, offering longer life and lower ESR (typically 50-80% reduction).
While not AEC-Q200 certified, it meets the temperature range (-55°C to +105°C) for many under-hood applications with proper derating.
MSL 3 requires baking after 168 hours exposure to ambient before reflow soldering (per IPC/JEDEC J-STD-033).
10,000+ hours at 105°C when operated within specifications (Vishay MTBF data).
Yes, but ensure proper PCB layout to avoid parasitic inductance negating ESR benefits.
Vishay's roadmap indicates:
Higher CV ratings in smaller cases (e.g., 47µF in 7343)
Integration with silicon for embedded passive solutions
Halogen-free materials for eco-design compliance
