UWT1A471MNL1GS

The UWT1A471MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UWT series, engineered for surface-mount applications on high-density printed circuit boards. It delivers 470 µF capacitance at a 10 V rating in a compact SMD can-style package suitable for automatic mounting with carrier tape.

Designed for demanding operating environments, this capacitor supports a wide temperature range of −55 °C to +105 °C, is RoHS compliant, and carries AEC-Q200 qualification for applications that require automotive-grade reliability.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Wide Temperature Range — Specified operation from −55 °C to +105 °C for use across harsh temperature environments.
• Automotive-Grade Reliability — AEC-Q200 qualified, suitable for designs that require automotive-level component qualification.
• Endurance — Rated for 1000 hours at 105 °C with the rated voltage applied; for capacitors ≤16 V the capacitance change after endurance is within ±25% of the initial value.
• Low-Temperature Performance — Impedance stability measured at 120 Hz with Z(−25 °C)/Z(+20 °C) up to 3 and Z(−40 °C)/Z(+20 °C) up to 8 at the 10 V rating.
• Loss and Leakage — tan δ (loss tangent) max of 0.24 at the 10 V rating (120 Hz, 20 °C); leakage current after 2 minutes at 20 °C is ≤ 0.01CV or 3 µA, whichever is greater (series specification).
• Ripple Current — 210 mA at 120 Hz and 315 mA at 10 kHz, supporting smoothing and decoupling in power rails.
• Surface-Mount Package — Radial can SMD package designed for automatic placement from carrier tape; compact dimensions L: 1.0 cm × D: 0.8 cm with recommended land pattern 8.3 mm × 8.3 mm.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Designed and AEC-Q200 qualified for use in automotive control modules and electronic subsystems requiring robust temperature and life performance.
• High-Density PCB Power Rails — Compact SMD can package and automatic placement compatibility make it suitable for decoupling and bulk storage on space-constrained boards.
• Embedded Power Modules — Provides bulk capacitance and ripple filtering where long life at elevated temperature (1000 h at 105 °C) is required.

Unique Advantages

• Wide operating temperature: −55 °C to +105 °C range enables deployment across harsh thermal environments without additional thermal derating considerations.
• AEC-Q200 qualification: Explicit qualification supports use in automotive designs and other applications demanding standardized reliability assurance.
• High capacitance in a compact SMD package: 470 µF in a 1.0 cm × 0.8 cm can reduces board footprint while maintaining energy storage capacity.
• Manufacturing-friendly format: Carrier-tape compatibility and surface-mount package simplify high-volume automated assembly.
• Proven endurance: 1000 hours at 105 °C with defined limits on capacitance change and leakage supports predictable long-term behavior in hot environments.
• Measured low-temperature impedance: Specified impedance ratios at −25 °C and −40 °C provide quantifiable performance for low-temperature designs.
