Key Features

• Electrostatic / Dielectric — Aluminum electrolytic construction delivering 470 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 10 V nominal rated voltage for low-voltage power systems.
• Low Impedance — Characteristic impedance of 80 mΩ to support transient and low-impedance filtering needs.
• Ripple Current Capability — Low-frequency ripple current 425 mA (120 Hz) and high-frequency ripple current 850 mA (10 kHz) for robust AC stress handling.
• Loss and Leakage — Tangent of loss angle (tanδ) 0.19 measured at 20°C, 120 Hz; measured leakage current listed as 47 µA.
• Temperature and Endurance — Rated operation from −55°C to +105°C with endurance specified at 2000 hours when tested at 105°C under rated voltage.
• Package & Mounting — Can-style SMD package (φ8×10L) with embossed carrier taping for automated surface-mount assembly; recommended land size 8.3 × 8.3 mm.
• Reliability & Compliance — AEC-Q200 rated and compliant to the RoHS directive (2011/65/EU, (EU)2015/863) per series documentation.
• Polarized — Polar capacitor for DC applications requiring correct polarity installation.

Typical Applications

• Automotive Electronics — Suited for board-level filtering and energy buffering in automotive control modules where AEC-Q200 qualification is required.
• Power Filtering — Used for DC-link, bulk decoupling and ripple attenuation in low-voltage power stages that need high ripple current capability and low impedance.
• Surface-Mount Assemblies — Ideal for compact SMD designs requiring automated placement and reliable soldering in high-density boards.

Unique Advantages

• High Ripple Handling: 425 mA (120 Hz) and 850 mA (10 kHz) ratings reduce temperature rise and extend service life under AC stress.
• Low ESR/Impedance: 80 mΩ impedance supports improved transient response and tighter voltage regulation in power circuits.
• Automated Assembly Ready: Embossed carrier taping and SMD can package streamline pick-and-place and reflow processes.
• Wide Temperature Range with Proven Endurance: −55°C to +105°C operation and 2000 h endurance at 105°C provide long-term stability in demanding environments.
• Automotive-Grade Qualification: AEC-Q200 rating supports designs targeting automotive electronics and other reliability-focused markets.
