• Tolerance & Polarization — Capacitance tolerance of −20% to +20%; polarized device.

Typical Applications

• Automotive power modules — Provides 330 µF at 50 V for bulk energy storage and smoothing in ECU power supplies, supported by AEC‑Q200 qualification and a −55 °C to 105 °C operating range.
• Infotainment and instrument clusters — Surface‑mount form factor and high capacitance make it suitable for decoupling and power stability on compact, high‑density boards.
• Motor control and power conversion — Ripple current ratings at both 120 Hz and 10 kHz help manage AC ripple in power electronics subsystems.
• Body electronics and modules — Long life specification (5000 hours at 105 °C) and RoHS compliance support replacement and long‑lived vehicle electronics designs.

Unique Advantages

• AEC‑Q200 automotive qualification: Enables use in automotive systems where component qualification is required.
• High‑capacitance SMD solution: 330 µF in a chip‑type radial can supports space‑constrained PCBs that still require bulk capacitance.
• Wide operating temperature and proven lifetime: −55 °C to 105 °C range and 5000 hours at 105 °C endurance provide predictable performance over time.
• Manufacturing‑friendly packaging: Designed for automatic mounting with carrier tape to streamline assembly on high‑volume production lines.
• Multifrequency ripple capability: Specified ripple currents at 120 Hz and 10 kHz accommodate both low‑frequency smoothing and higher‑frequency decoupling needs.
