UCL1A331MCL6GS

The UCL1A331MCL6GS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon's UCL series, supplied in a compact surface-mount can package. It delivers 330 µF capacitance at a 10 V rating with engineered low impedance and rated ripple capability for demanding power environments.

Targeted for automotive and other power-critical applications, this part provides high ripple handling, low loss (tan δ 0.19 at 20°C/120 Hz for 10 V), and a wide operating temperature range to support robust power rail smoothing and high-ripple conditions.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 10 V rated voltage and a capacitance tolerance of −20% to +20%.
• Low Loss — tan δ = 0.19 (measured at 20°C, 120 Hz for 10 V), offering controlled dielectric losses for stable performance in AC environments.
• Low Impedance Construction — specified impedance of 100 mΩ to support lower ESR in power circuits.
• Ripple Current Handling — 425 mA at 120 Hz (low frequency) and 850 mA at 10 kHz (high frequency), enabling operation under continuous ripple loads.
• Leakage Current — leakage current specified at 33 µA after standard voltage application, supporting predictable standby and bias behavior.
• Thermal Endurance — rated for 2,000 hours at 105°C, with an operating temperature range from −55°C to +105°C.
• Package & Mounting — surface-mount radial can (chip type) with a φ10 mm diameter; supplied in embossed carrier taping for automated assembly.
• AEC-Q200 Qualified — rated to AEC-Q200, suitable for automotive electronics where that qualification is required.
• RoHS Compliant — meets RoHS environmental requirements.

Typical Applications

• Automotive Power Modules — bulk smoothing and filtering on vehicle power rails where AEC-Q200 qualification and high ripple capability are required.
• DC-DC Converters — output-side decoupling and energy storage to support stable voltage regulation under fluctuating loads.
• High-Ripple Power Systems — circuits that require sustained ripple handling at both low and high frequencies, leveraging specified ripple current ratings.

Unique Advantages

• High Ripple Tolerance: Ripple current ratings at both 120 Hz and 10 kHz let designers specify the capacitor for mixed-frequency load conditions.
• Predictable Loss Characteristics: Measured tan δ (0.19 at 10 V, 120 Hz, 20°C) provides a verifiable basis for thermal and performance calculations.
• Robust Endurance: 2,000-hour life at 105°C supports long-term operation in elevated-temperature environments.
• Automotive-Grade Qualification: AEC-Q200 rating enables use in designs that require automotive component-level qualification.
• Compact SMD Can Package: Chip-type radial can in embossed carrier taping simplifies pick-and-place, while a φ10 mm can diameter conserves board area compared with larger radial options.
