Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 16 V, ±20% tolerance, suitable for bulk energy storage and decoupling on power rails.
• Low Impedance — Specified impedance of 80 mOhm supports stable voltage regulation and reduced ripple on DC rails.
• High Temperature Operation — Rated for -55 °C to +105 °C with endurance verified to 2000 hours at 105 °C, supporting prolonged operation in elevated temperature environments.
• Ripple Current Capability — 425 mA at 120 Hz and 850 mA at 10 kHz frequency ratings, enabling effective ripple handling across common switching frequencies.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant, providing traceable qualification for automotive and high‑reliability applications.
• Surface‑Mount, Tape‑Fed Packaging — Chip‑type radial can SMD package designed for automatic mounting machines fed with carrier tape; recommended land size 8.3 × 8.3 mm.
• Leakage & Dissipation — Leakage current specified as ≤ 0.01CV (µA) after 2 minutes at 20 °C; tan δ maximum 0.16 at 16 V (measured at 120 Hz, 20 °C).

Typical Applications

• Automotive Power Modules — Bulk capacitance and AEC‑Q200 qualification make this part suitable for smoothing and energy storage in automotive power supply modules and DC‑DC converters.
• Power Rail Decoupling — Low impedance and high ripple current ratings help stabilize voltage rails in embedded control electronics operating at elevated temperatures.
• Electronic Control Units (ECUs) — High temperature endurance (2000 h at 105 °C) and surface‑mount compatibility support ECU designs requiring compact, reliable energy storage.

Unique Advantages

• AEC‑Q200 Qualification: Provides component‑level qualification for automotive and other high‑reliability systems, reducing qualification burden for end products.
