UUX1E331MNL1GS

The UUX1E331MNL1GS is a surface‑mount aluminum electrolytic capacitor in Nichicon’s UUX series. It delivers 330 µF at 25 V in a compact φ10 × 10 mm can‑type SMD package designed for applications that require wide temperature operation and extended endurance.

Key attributes include a wide operating temperature range, AEC‑Q200 rating for automotive use, and measured loss characteristics suited to power‑handling tasks where ripple current and long life at elevated temperature matter.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 25 V maximum rating and tolerance of −20% to +20%.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C, enabling use across harsh thermal environments.
• Endurance — 2000 hours rated life at 105 °C to support long‑term stability in elevated‑temperature applications.
• Loss Performance (tan δ) — Tanδ of 0.14 measured at 20 °C, 120 Hz, providing a verified dissipation factor for design calculations.
• Ripple Current Capability — Low‑frequency ripple current of 372 mA (120 Hz) and high‑frequency ripple current of 483.6 mA (10 kHz), useful when accounting for AC stress in power paths.
• Leakage Current — Specified leakage current of 247.5 µA for predictable bias current budgeting.
• Package & Assembly — φ10 × 10 mm radial can in an SMD form factor with embossed carrier taping for automated placement; surface‑mount land size 10.3 × 10.3 mm.
• Qualification — AEC‑Q200 rated, supporting automotive system requirements where that specification is required.

Typical Applications

• Automotive Electronic Systems — Designed for automotive electronics that require AEC‑Q200 qualified capacitors and a wide −55 °C to +105 °C operating range.
• Power Supply Filtering — Provides bulk capacitance and ripple handling in DC‑DC converter outputs and intermediate rails where 25 V rating and high ripple current are needed.
• Surface‑Mount Power Modules — Compact φ10 × 10 mm SMD package and embossed carrier taping allow integration into automated SMT assembly for power modules and control units.

Unique Advantages

• AEC‑Q200 Reliability: Meets AEC‑Q200 requirements, making the part suitable for automotive program qualification and designs requiring automotive‑grade components.
• Wide Thermal Endurance: −55 °C to +105 °C operation and 2000 h endurance at 105 °C support long life in thermally demanding environments.
• High Ripple Handling: Defined ripple current ratings at 120 Hz and 10 kHz allow engineers to size capacitors against both low‑ and high‑frequency AC stress.
• Predictable Electrical Parameters: Specified tanδ (0.14 at 20 °C, 120 Hz) and measured leakage current enable accurate thermal and leakage budgeting in system designs.
• SMT‑Friendly Packaging: Embossed carrier taping and a compact SMD can form factor simplify automated assembly and reduce PCB area compared to larger discrete options.
• Manufacturer and Series Support: Part of Nichicon’s UUX series, providing consistency of form and performance for multi‑design rollouts.
