UCL1V331MNL1GS

The UCL1V331MNL1GS is a Nichicon UCL series surface-mount aluminum electrolytic capacitor in a chip-type, low-impedance can. It delivers 330 µF capacitance at a 35 V rating in a compact φ10 × 10 mm package with embossed carrier taping for automated placement.

Designed for demanding temperature and ripple environments, the part offers an operating range of −55℃ to 105℃, AEC-Q200 rating, and 2,000 hours endurance at 105℃, making it appropriate for automotive and other robust electronic power systems where long-term stability and ripple handling are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 35 V and ±20% tolerance at 120 Hz, 20℃.
• Low Impedance — Rated impedance of 60 mΩ supports low-loss filtering and decoupling in power rails.
• Ripple Current Performance — Low-frequency ripple current 595 mA at 120 Hz and high-frequency ripple current 1.19 A at 10 kHz for effective smoothing across a range of switching frequencies.
• Thermal & Endurance — Operating temperature −55℃ to 105℃ with 2,000 hours rated endurance at 105℃; suitable for elevated-temperature duty cycles.
• Loss Tangent — tan δ of 0.12 measured at 20℃, 120 Hz (for 35 V rating) for predictable ESR/DF behavior in AC conditions.
• Leakage Current — Specified leakage current of 115.5 µA (product specification).
• Package & Mounting — Chip-type radial can for surface-mount placement; available in embossed carrier taping for high-volume assembly.
• Qualification — AEC-Q200 rated, supporting use in applications requiring component-level automotive-grade qualification.

Typical Applications

• Automotive power supply filtering — Bulk and decoupling capacitor for 35 V rails requiring 330 µF storage and ripple handling up to 1.19 A at switching frequencies.
• DC–DC converter outputs — Output smoothing in converters where low impedance (60 mΩ) and robust ripple capability improve voltage stability.
• Engine control and electronic modules — Energy smoothing and filtering in electronic control units that operate across −55℃ to 105℃ and require AEC-Q200-rated components.

Unique Advantages

• AEC-Q200 rating: Provides a component-level qualification that supports deployment in automotive-grade electronic systems.
• High ripple tolerance across frequencies: Separate low-frequency (595 mA at 120 Hz) and high-frequency (1.19 A at 10 kHz) ripple current specs let designers size capacitors confidently for both linear and switching environments.
• Compact chip-type SMD package: φ10 × 10 mm form factor and embossed carrier taping enable automated assembly while conserving board area.
• Wide operating temperature and proven endurance: −55℃ to 105℃ rating with 2,000 h endurance at 105℃ supports long-term reliability in elevated-temperature applications.
• Predictable electrical behavior: Low impedance (60 mΩ) and defined tan δ (0.12 at 35 V, 120 Hz) simplify simulation and thermal budgeting in power designs.
