It provides a higher-capacitance SMD option with series-level characteristics targeted at applications that require bulk capacitance, ripple handling and defined lifetime performance.

Designed for reliability in demanding environments, this part features an operating temperature range of −40°C to 85°C, a 2000-hour endurance rating at 85°C, and AEC-Q200 qualification for use in applications that require automotive-level component qualification.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 50 V DC rating suitable for medium-voltage power rails.
• Loss Characteristics — tanδ (DF) 0.12 measured at 20°C, 120 Hz and 50 V, indicating the specified dissipation factor at rated conditions.
• Leakage Current — 705 µA specified leakage current after application of rated voltage (product-specific value).
• Ripple Current Capability — Low-frequency ripple 740 mA at 120 Hz and high-frequency ripple 1.11 A at 10 kHz, for smoothing and bulk-energy applications.
• Reliability & Endurance — Life rating of 2000 hours at 85°C; meets AEC-Q200 requirements.
• Package & Mounting — Surface-mount radial can (SMD) in a φ16 × 16.5 mm case; supplied in embossed carrier taping for automated placement.
• Environmental Range — Operating temperature −40°C to 85°C, suitable for a wide range of ambient conditions.

Typical Applications

• Automotive Electronics — Use in automotive control modules and power rails where AEC-Q200 qualification and an operating range down to −40°C are required.
• Power Supply Filtering — Bulk smoothing and decoupling on intermediate and output rails for DC‑DC converters and regulators at up to 50 V.
• High‑Ripple Power Circuits — Energy reservoir and ripple attenuation in circuits exposed to low- and high-frequency ripple currents (specified at 120 Hz and 10 kHz).
• Industrial Equipment — Bulk capacitance for controllers, drives, and other industrial electronics operating within −40°C to 85°C.

Unique Advantages

• High bulk capacitance in an SMD chip — 470 µF in a φ16 × 16.5 mm SMD can provides significant energy storage while supporting surface-mount assembly.
• Defined loss and leakage parameters — Specified tanδ (0.12 at 50 V, 120 Hz) and a quantified leakage current (705 µA) simplify thermal and leakage budgeting in designs.
• Designed for ripple-intensive circuits — Rated ripple currents of 740 mA (120 Hz) and 1.11 A (10 kHz) permit confident use in both low- and high-frequency smoothing applications.
• Qualified endurance — 2000 hours at 85°C provides a quantified lifetime expectation for reliability planning.
• Embossed carrier taping — Packaging supports automated pick-and-place flow for production assembly.
• AEC-Q200 rated — Component qualification suitable for designs requiring AEC-Q200 compliance.
