UUL1A471MNL1GS

The Nichicon UUL1A471MNL1GS is a chip‑type aluminum electrolytic capacitor specified at 470 µF and 10 V in a compact surface‑mount radial can package. It is designed for surface mounting on high‑density PC boards and targets applications that require long life and reliable operation in elevated temperatures.

Key value propositions include a rated operating range from -40 °C to 105 °C, a guaranteed load life of 5000 hours at 105 °C, AEC‑Q200 qualification, and RoHS compliance—making it suitable for demanding electronic systems where durability and compact SMD integration are required.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance for bulk energy storage in compact circuits.
• Long Life at Elevated Temperature: Load life specified as 5000 hours at 105 °C, with endurance characteristics defined after restoration to 20 °C following the test.
• Temperature Range: Category temperature range from -40 °C to +105 °C, suitable for broad ambient conditions.
• Automotive Reliability: AEC‑Q200 Qualified, supporting designs that require recognized component qualification for automotive electronics.
• Surface‑mount, Chip‑Type Package: Chip type radial can SMD designed for high‑density PCB mounting; package dimensions approximately L: 1 × D: 1 cm and recommended land size L: 1.03 × W: 1.03 cm.
• Ripple Current Ratings: Specified ripple current of 254 mA at 120 Hz and 381 mA at 10 kHz, useful for evaluating performance in power filtering and decoupling roles.
• Leakage & Dissipation: Series leakage current specification: after 2 minutes at rated voltage and 20 °C, leakage ≤ 0.01 CV or 3 µA (whichever is greater); tan δ for 10 V rated voltage is specified at 0.24 (max) at 120 Hz, 20 °C.
• Regulatory Compliance: Compliant to the RoHS directive (2011/65/EU and (EU)2015/863), supporting environmental requirements.

Typical Applications

• Automotive Electronics: Intended for automotive applications where AEC‑Q200 qualification and extended high‑temperature life are required.
• High‑Density Surface‑Mount PCBs: Designed specifically for surface mounting on high‑density printed circuit boards where compact, chip‑type SMD capacitors are needed.
• Power Filtering in Elevated Temperatures: Suited for power supply filtering and bulk energy tasks in environments up to 105 °C, with defined ripple current ratings for design verification.

Unique Advantages

• Extended High‑Temperature Endurance: 5000 hours load life at 105 °C reduces maintenance and replacement frequency in temperature‑stressed designs.
• AEC‑Q200 Qualification: Provides a recognized qualification baseline for automotive and similarly demanding system designs.
• Compact SMD Form Factor: Chip‑type radial can SMD with a small footprint (approx. 1 × 1 cm) eases integration into dense board layouts.
• Measured Ripple Performance: Published ripple current values at 120 Hz and 10 kHz enable straightforward thermal and reliability assessments in power applications.
• Regulatory Compliance: RoHS compliance supports deployment in regions and programs with environmental requirements.
