UUA1H3R3MCL1GS

The UUA1H3R3MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UUA series, specified as a surface-mount component for high-density PCBs. It provides 3.3 µF capacitance at a 50 V rating in a compact L: 5.8 × D: 4 mm can-style SMD package.

Designed for demanding environments, the part is RoHS compliant and AEC-Q200 qualified, offering a rated operating range of −55 °C to +105 °C and a specified load life of 3000 hours at +105 °C for this size.

Key Features

• Electrical Performance: 3.3 µF capacitance at 50 V with ±20% tolerance and polarized construction; leakage current specified as ≤ 0.01·C·V or 3 μA (whichever is greater) after 2 minutes at 20 °C.
• Low-loss characteristics: Maximum tan δ of 0.12 at 120 Hz (for 50 V nominal) for predictable AC performance in filtering and decoupling applications.
• Ripple handling: Ripple current ratings of 17 mA at 120 Hz and 25.5 mA at 10 kHz to address low- and high-frequency ripple components.
• Compact SMD package: Chip-type radial can SMD format, overall dimension L: 5.8 × D: 4 mm with recommended land size L: 4.3 × W: 4.3 mm, enabling high-density placement on PCBs.
• Temperature and longevity: Rated for −55 °C to +105 °C operation with a guaranteed load life of 3000 hours at +105 °C for this diameter class.
• Reliability and manufacturing robustness: AEC-Q200 qualified and RoHS compliant; withstands soldering heat per the datasheet condition (hot plate 30 s at 250 °C) with capacitance change within ±10% after reflow condition.
• Marking and identification: Black print on the case top for part identification.

Typical Applications

• Automotive power modules: AEC-Q200 qualification and 105 °C endurance make this capacitor suitable for power decoupling and smoothing in automotive control units and power electronics.
• High-density PCB designs: The 6 mm chip-type SMD format and small footprint support compact assemblies where board space is limited.
• DC–DC converter outputs and power rails: Low leakage and defined ripple current ratings help stabilize voltage rails and filter switching noise across low- and high-frequency components.

Unique Advantages

• Space-efficient SMD can: The 5.8 × 4 mm package and recommended 4.3 × 4.3 mm land pattern lets designers conserve board area without sacrificing capacitance.
• High-temperature endurance: Rated for operation to +105 °C with a specified 3000-hour load life at that temperature for this form factor, supporting long-term reliability in hot environments.
• Automotive-grade reliability: AEC-Q200 qualification addresses automotive design requirements for component robustness and traceability.
• Predictable AC behavior: Specified tan δ and ripple current values at 120 Hz and 10 kHz enable accurate selection for filtering and decoupling tasks.
• Regulatory compliance: RoHS (2011/65/EU, (EU)2015/863) compliance supports environmental and regulatory requirements for production.
