UUQ1C331MCL1GS

The UUQ1C331MCL1GS is a chip-type aluminum electrolytic capacitor designed for compact, surface-mount applications. It combines a 330 µF capacitance and 16 V rated voltage with a chip-style radial can SMD package suitable for automated assembly via carrier tape.

Targeted for audio equipment and automotive electronics, this capacitor offers a wide operating temperature range and AEC-Q200 qualification for designs that require verified reliability across harsh environments.

Key Features

• Capacitance & Voltage — 330 µF capacitance at a 16 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• Temperature Range — Rated for operation from −40°C to +105°C, supporting extended-temperature applications.
• AEC-Q200 Qualified — AEC-Q200 rating for applications requiring automotive-grade qualification.
• Endurance — Designed to meet endurance: capacitance change within ±20% after 1000 hours at 105°C with rated voltage applied.
• Leakage & Loss Characteristics — Leakage current spec of not more than 0.03 CV or 4 µA (whichever is greater) after 1 minute at 20°C; tan δ (16 V) max 0.22 at 120 Hz, 20°C.
• Ripple Current Performance — 210 mA at 120 Hz and 315 mA at 10 kHz for effective filtering and decoupling in power circuits.
• Low-Temperature Stability — Impedance ratios for 16 V: Z(−25°C)/Z(+20°C) = 2 and Z(−40°C)/Z(+20°C) = 4, enabling predictable behavior in cold environments.
• Package & Mounting — Chip-type radial can SMD for surface-mount placement; compatible with automatic placement from carrier tape and a surface-mount land recommended at 8.3 × 8.3 mm.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) environmental requirements.

Typical Applications

• Automotive Electronics — Power filtering and decoupling in modules where AEC-Q200 qualification and −40°C to +105°C operation are required.
• Audio Equipment — Chip-type acoustic series design intended for audio circuits that need stable capacitance and low loss over temperature.
• Embedded Power Modules — Bulk decoupling and smoothing in compact, surface-mount power supplies for industrial and vehicle systems.

Unique Advantages

• Automotive-Grade Qualification: AEC-Q200 qualification provides documented reliability criteria for automotive and other demanding applications.
• Wide Operating Temperature: −40°C to +105°C rating and 1000-hour endurance at 105°C help ensure performance across harsh environments.
• Assembly-Ready Chip Form: Chip-type radial can SMD format and carrier-tape compatibility streamline automated surface-mount assembly.
• Measured Ripple Handling: Specified ripple current values at 120 Hz and 10 kHz give designers clear parameters for power-filtering performance.
• Predictable Low-Temperature Behavior: Published impedance ratios at −25°C and −40°C enable reliable design margins for cold-start and low-temp operation.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements for modern electronics supply chains.
