UUQ0J331MCL1GS

The UUQ0J331MCL1GS is a chip-type aluminum electrolytic capacitor in Nichicon’s UUQ series, offering 330 µF capacitance at a 6.3 V rating. It is designed as a compact SMD radial can for automated assembly and for use in audio and electronic systems that require wide operating temperature performance.

Key value propositions include AEC‑Q200 qualification, RoHS compliance, and robust endurance across a −40 °C to +105 °C operating range, providing reliable decoupling and filtering in temperature-challenging environments.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 6.3 V nominal working voltage and ±20% tolerance (120 Hz, 20 °C).
• Wide Temperature Range — Rated for operation from −40 °C to +105 °C, enabling use across broad thermal environments.
• AEC‑Q200 Qualified — Meets AEC‑Q200 qualification as specified in the product data, supporting designs that require automotive-grade component qualification.
• Endurance — Specified endurance of 1,000 hours at 105 °C with capacitance change within ±20%, and leakage current remaining ≤ initial specified value after the test.
• Leakage Current — After 1 minute at rated voltage and 20 °C, leakage current is ≤ 0.03 CV or 4 µA, whichever is greater.
• Loss and Stability — Maximum tan δ of 0.30 at 6.3 V (measured at 120 Hz, 20 °C); low-temperature impedance ratios for 6.3 V are Z(−25 °C)/Z(+20 °C) = 4 and Z(−40 °C)/Z(+20 °C) = 8.
• Ripple Current — Rated ripple current of 102 mA at 120 Hz and 153 mA at 10 kHz, suitable for typical decoupling and filtering tasks in circuits with moderate ripple.
• Package & Mounting — Chip-type radial can SMD package, size L: 6.2 × D: 8 mm, designed for surface-mount assembly and compatible with automatic mounting machines fed with carrier tape. Recommended PCB land size: 8.3 × 8.3 mm.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suited for electronic modules where AEC‑Q200 qualification and a −40 °C to +105 °C operating window are required.
• Audio Equipment — Part of the chip-type acoustic series intended for audio applications that demand stable electrolytic capacitance across a wide temperature range.
• Surface-Mount Assemblies — Designed for automated pick-and-place assembly using carrier tape, enabling efficient integration into high-volume SMD production.

Unique Advantages

• Automotive-Grade Qualification: AEC‑Q200 qualification provides a documented level of reliability for critical electronic systems.
• Wide Temperature Endurance: Rated −40 °C to +105 °C with 1,000-hour endurance at 105 °C, supporting sustained performance in thermally demanding applications.
• Compact SMD Form Factor: 6.2 × 8 mm chip-type radial can and an 8.3 × 8.3 mm recommended land pattern enable density-friendly board layouts.
• Measured Ripple Performance: Specified ripple currents at both low and high frequencies (102 mA at 120 Hz, 153 mA at 10 kHz) make the part suitable for common filtering and decoupling roles.
• Controlled Leakage & Loss: Defined leakage current limits and tan δ values support predictable behavior in precision and audio circuits.
• RoHS Compliance: Conforms to current RoHS directives for use in regulated markets.
