Targeted for automotive applications, this part is AEC-Q200 qualified and RoHS compliant. Key electrical and reliability attributes include a 10 V rating, low equivalent series resistance, wide operating temperature range, and a long endurance specification at elevated temperature.

Key Features

• Electrical Performance — 4.7 mF rated capacitance at 10 V with ±20% tolerance, providing bulk energy storage for decoupling and smoothing tasks.
• ESR and Ripple Handling — Equivalent series resistance of 280 mΩ at 120 Hz, with specified ripple currents of 1.2 A at 120 Hz and 1.38 A at 10 kHz for handling AC ripple and transient currents.
• Temperature and Endurance — Rated for -55 °C to 105 °C operation and specified for 5000 hours at 105 °C with defined limits on capacitance change, tan δ, and leakage current after endurance testing.
• Package and Mounting — Chip-type radial can SMD package sized L: 2.15 × D: 1.8 cm with a recommended surface-mount land size of 1.83 × 1.83 cm; compatible with carrier-tape automated placement.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant, suitable for regulated manufacturing and automotive-grade design considerations.
• Polarized, High-Capacitance Range — Polarized aluminum electrolytic construction optimized for higher capacitance values in chip-type SMD form factors.

Typical Applications

• Automotive systems — Suitable for automotive electronics where AEC-Q200 qualification and extended temperature endurance are required.
• High-density SMD boards — Designed for surface mounting on densely populated PCBs and compatible with automatic carrier-tape placement.
• Power decoupling and smoothing — Provides bulk capacitance and ripple current capability for power rails and transient suppression in compact assemblies.

Unique Advantages

• AEC-Q200 Qualified: Meets an industry-recognized automotive stress qualification, supporting use in automotive electronics and other demanding environments.
• High Capacitance in SMD Form: 4.7 mF nominal capacitance in a chip-type radial can enables substantial energy storage without through-hole mounting.
• Long High-Temperature Endurance: Specified for 5000 hours at 105 °C, providing predictable aging characteristics for long-life applications.
• Low ESR and Defined Ripple Ratings: 280 mΩ ESR at 120 Hz and ripple current ratings at 120 Hz and 10 kHz reduce loss and heating under AC ripple conditions.
• Assembly-Friendly Package: Surface-mount, carrier-tape compatible packaging simplifies automated placement on high-density PCBs.
• RoHS Compliant: Conforms to RoHS directives for use in regulated manufacturing environments.
