UUA1A331MNL1GS

The UUA1A331MNL1GS is a chip-type aluminum electrolytic capacitor designed for surface-mount applications. It delivers 330 µF capacitance at a 10 V rating with a compact 10 × 10 mm footprint and a chip-style radial can SMD construction.

Targeted for automotive and other demanding environments, the part combines long life (5,000 hours at 105°C), AEC-Q200 qualification, and RoHS compliance to support high-density, reliability-focused electronic assemblies.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 10 V with ±20% tolerance for bulk energy storage and smoothing in compact SMD form.
• Electrical Loss — tanδ 0.24 (measured at 120 Hz, 20°C) for predictable ESR-related behavior at low frequencies.
• Ripple Handling — 290 mA ripple current at 120 Hz (low frequency) and 435 mA at 10 kHz (high frequency), enabling effective filtering across a range of switching and line conditions.
• Leakage Current — 33 µA leakage current specification for stable performance after voltage application.
• Reliability & Lifetime — Rated for 5,000 hours at 105°C; AEC-Q200 qualified for automotive-grade reliability demands.
• Temperature Range — Guaranteed operation from −55°C to 105°C to support wide operating environments.
• Package & Assembly — Chip-type radial can SMD designed for surface-mount assembly with embossed carrier taping for automated placement. Recommended surface-mount land size: 10.3 × 10.3 mm.
• Regulatory — RoHS compliant.
• Production Status — Available in mass production quantities.

Typical Applications

• Automotive electronics — AEC-Q200 qualified chip capacitor suitable for power filtering and decoupling in automotive control modules and electronic subsystems.
• Power management modules — Compact 330 µF, 10 V rating and defined ripple current figures make it suitable for DC-DC converter output filtering and bulk smoothing in high-density boards.
• Embedded systems — Long life at elevated temperature and a wide operating temperature range support reliable operation in space-constrained, demanding embedded applications.

Unique Advantages

• AEC-Q200 qualification: Demonstrates suitability for automotive electronic environments that require component-level stress qualification.
• Long life at elevated temperature: 5,000 hours at 105°C provides predictable endurance for designs exposed to sustained high temperature.
• High ripple capability across frequencies: Specified ripple currents at 120 Hz and 10 kHz give designers quantified performance for both line-frequency smoothing and switching-regulator applications.
• Compact SMD chip form factor: 10 × 10 mm footprint and embossed carrier taping streamline automated assembly while minimizing PCB area.
• Wide operating range: −55°C to 105°C operation supports deployment across a broad set of environmental conditions.
• Regulatory compliance and production readiness: RoHS compliance and mass production availability simplify procurement and design-in.
