UWZ1V331MCL1GS

The UWZ1V331MCL1GS is a chip-type aluminum electrolytic surface-mount capacitor designed for robust power decoupling and energy storage in demanding environments. It combines a compact radial can SMD package with a high-capacitance 330 μF, 35 V rating and polarized construction for board-level power applications.

Engineered for wide temperature operation and rugged assembly, this part supports –55°C to +105°C operation, AEC-Q200 qualification, RoHS compliance, and compatibility with high-temperature reflow processes up to a 260°C peak for automated surface-mount production.

Key Features

• Capacitance & Voltage: 330 μF nominal capacitance at a 35 V rating with ±20% tolerance, providing stable bulk energy storage for power rails and decoupling.
• Chip SMD Package: Radial, can-style SMD package suitable for automated mounting by carrier tape; nominal size L: 1 × D: 1 cm with surface-mount land size 1.03 × 1.03 cm.
• Wide Temperature Range: Rated for –55°C to +105°C operation, enabling use across industrial and automotive temperature environments.
• High-temperature Reflow Compatibility: Compatible with 260°C peak reflow soldering. Recommended reflow condition: 260°C peak 5 s; 230°C over 60 s two times (φ8 × 6.2, φ10 × 10: 1 time), allowing integration into lead-free SMT assembly flows.
• Reliability & Lifetime: Endurance rated for 1000 hours at 105°C with defined limits on capacitance change (within ±20% for rated voltages ≥20 V), tan δ and leakage current retention.
• Ripple & Leakage Characteristics: Ripple current: 300 mA at 120 Hz and 450 mA at 10 kHz. Leakage current after 2 minutes at 20°C is ≤ 0.01CV or 3 μA (whichever is greater), supporting stable performance in power applications.
• Low-temperature Performance & Loss: Tan δ (max.) at 120 Hz, 20°C is 0.14 for 35 V parts; impedance ratios for low-temperature stability include Z(–25°C)/Z(+20°C) = 2 and Z(–40°C)/Z(+20°C) = 3 for 35 V rating.
• Standards Compliance: AEC-Q200 Qualified and RoHS compliant (2011/65/EU.(EU)2015/863), suitable for designs requiring recognized quality and environmental compliance.

Typical Applications

• Automotive Electronics: Bulk filtering and energy storage in in-vehicle power systems and modules that require AEC-Q200 qualification and –55°C to +105°C operation.
• Power Supply Filtering: Smoothing and decoupling for DC–DC converters and voltage regulators where 330 μF at 35 V and defined ripple current capability improve transient response.
• Industrial Controls: Power buffering and noise suppression in industrial control units and power modules exposed to wide temperature ranges and long operating lifetimes.
• Automated SMT Production Lines: Designed for carrier-tape feeding and high-temperature reflow assembly, simplifying integration into automated manufacturing processes.

Unique Advantages

• Automated Assembly Ready: Carrier-tape compatibility and 260°C peak reflow support enable straightforward integration into lead-free SMT production lines.
• Automotive-grade Reliability: AEC-Q200 qualification and 1000-hour endurance at 105°C provide documented performance for automotive and similarly demanding applications.
• High Capacitance in Compact SMD Form: 330 μF in a 1 × 1 cm footprint delivers substantial bulk capacitance for constrained board space.
• Wide Operating Temperature: –55°C to +105°C range supports deployment across harsh thermal environments without loss of functionality.
• Measured AC & Low-temperature Characteristics: Specified tan δ, impedance ratios, and ripple current ratings give engineers the data needed to size the capacitor confidently for transient and frequency-dependent behavior.
• Proven Soldering Robustness: Resistance-to-soldering-heat and hot-plate test criteria ensure retained electrical characteristics after standard assembly processes.
