UCQ1E331MCL1GS

The UCQ1E331MCL1GS is a surface-mount aluminum electrolytic capacitor in the UCQ series designed for applications that require robust performance across a wide temperature range. It delivers 330 µF capacitance at 25 V in a compact φ10 × 10 mm SMD can, and is supplied in embossed carrier taping compatible with automatic placement.

Targeted for audio equipment and automotive systems, this part combines high ripple-current capability, AEC-Q200 qualification, and long endurance at elevated temperature for reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Loss Tangent (tan δ) — tan δ = 0.16 measured at 20°C, 120 Hz for the 25 V rating, providing defined dissipation characteristics for circuit design.
• Ripple Current Performance — Low-frequency ripple current 400 mA (120 Hz) and high-frequency ripple current 600 mA (10 kHz), supporting applications with significant AC stress.
• Leakage Current — Specified leakage current of 82.5 µA for predictable standby behavior.
• Temperature & Endurance — Operates from −55°C to +105°C with an endurance rating of 2000 hours at 105°C.
• Packaging & Mounting — φ10 × 10 mm radial SMD can supplied in embossed carrier taping for automatic mounting machines.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated environments and automotive-grade programs.

Typical Applications

• Automotive Electronics — Suitable for electronic modules in automotive systems where AEC-Q200 qualification and wide temperature operation are required.
• Audio Equipment — Designed for SMD audio applications, offering stable capacitance and defined loss characteristics across temperature.
• SMD Power Assemblies — Compact chip-style can and embossed carrier tape make it appropriate for densely packed surface-mount PCBs assembled by automatic placement.

Unique Advantages

• Wide Temperature Range: −55°C to +105°C rating supports operation in harsh and variable environments.
• Automotive-Grade Qualification: AEC-Q200 qualification supports integration into automotive projects that require component-level qualification.
