UUL1C471MNL1GS

The UUL1C471MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UUL series, designed for surface mounting on high-density printed circuit boards. It delivers 470 µF capacitance at a 16 V rating with polarized construction and is intended for applications that require long-term reliability in demanding temperature environments.

Key value drivers include a 5000-hour rated lifetime at +105°C, AEC-Q200 qualification for automotive use, and RoHS compliance, making it suitable for compact, high-reliability designs where space and endurance matter.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a 16 V rated voltage with ±20% tolerance, providing substantial charge storage in a compact chip package.
• Long-Life Endurance — Rated for 5000 hours at +105°C; endurance specifications require capacitance, tan δ and leakage current to meet defined limits after the life test.
• Wide Operating Temperature — Specified operating range from −40°C to +105°C suitable for temperature-challenging environments.
• Surface-Mount Chip Package — Chip-type, radial can SMD package designed for high-density PCB assembly; part dimensions approximately 1 cm × 1 cm with recommended land pattern around 1.03 cm × 1.03 cm.
• Electrical Performance — Ripple current capacity of 254 mA at 120 Hz and 381 mA at 10 kHz, supporting dynamic power conditions in compact power assemblies.
• Leakage Current Spec — Leakage current limited per series specification (after 2 minutes at rated voltage: not more than 0.01 CV or 3 µA, whichever is greater), ensuring predictable DC behavior.
• Compliance & Qualification — AEC-Q200 qualified and RoHS compliant (2011/65/EU and (EU)2015/863), aligning with automotive qualification expectations and environmental regulations.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and long-life rating make this capacitor suitable for automotive onboard electronics that demand durability and temperature resilience.
• High-Density Surface-Mount Assemblies — Chip-type SMD form factor and a compact 1 cm × 1 cm footprint enable use on densely populated PCBs where board space is constrained.
• Wide-Temperature or Harsh-Environment Systems — Operates from −40°C to +105°C with a 5000-hour life at +105°C, supporting designs exposed to extended temperature ranges.

Unique Advantages

• Long-term thermal reliability: 5000-hour rated life at +105°C provides predictable aging behavior for designs requiring extended high-temperature endurance.
• Automotive-grade qualification: AEC-Q200 rating supports integration into automotive electronic assemblies where industry qualification is required.
• High capacitance in a small SMD package: 470 µF at 16 V in a 1 cm × 1 cm chip simplifies BOM and conserves PCB area.
• Designed for surface-mount high-density boards: Chip-type can and recommended land pattern (≈1.03 cm × 1.03 cm) streamline assembly on compact PCBs.
• Measured ripple capability: Specified ripple current values (254 mA at 120 Hz, 381 mA at 10 kHz) help designers evaluate suitability for filtering and dynamic loads.
• Regulatory and environmental compliance: RoHS compliance ensures conformance to relevant environmental directives.
