UUG1A102MNQ1MS

The UUG1A102MNQ1MS is a Nichicon UUG series aluminum electrolytic surface-mount capacitor offering 1000 µF capacitance at a 10 V rated voltage. It is a chip-type, high-capacitance SMD device designed for power filtering and energy storage in compact assemblies.

Key attributes include a wide operating temperature range of −40°C to +85°C, AEC-Q200 rating for automotive applications, and a 2000-hour endurance at 85°C. Product status: Not recommended for new designs.

Key Features

• Capacitance & Voltage 1000 µF (1 mF) nominal capacitance with a 10 V rated voltage and ±20% tolerance for bulk decoupling and smoothing.
• Loss and Leakage tanδ 0.24 (at 10 V, 120 Hz) and leakage current specified at 300 µA provide clear electrical limits for design verification.
• Ripple Current Performance Rated ripple current of 620 mA at 120 Hz (low frequency) and 713 mA at 10 kHz (high frequency) to support ripple filtering on power rails.
• Reliability & Endurance AEC-Q200 rated with 2000 hours life at 85°C; endurance guarantees capacitance within ±20% and tanδ within specified limits after testing.
• Temperature Range Operates across −40°C to +85°C for a broad range of environmental conditions.
• Package & Mounting Chip-type radial can SMD package, φ12.5 × 13.5 mm (D × L), surface-mount land size 12.8 × 12.8 mm, supplied in embossed carrier taping for automated placement.

Typical Applications

• Automotive power rails — Bulk decoupling and smoothing on 10 V subsystems where AEC-Q200 qualification is required.
• DC–DC converter outputs — Provide high-capacitance energy storage and ripple attenuation for regulator output stages.
• Backup hold-up caps — Short-term energy reservoir for microcontroller or RTC hold-up during transient events.
• Industrial power modules — Filtering and stabilization in compact SMD layouts across −40°C to +85°C operating range.

Unique Advantages

• High capacitance in an SMD package: 1000 µF in a φ12.5 × 13.5 mm chip-type can reduces board footprint compared with larger through-hole parts.
• Automotive-capable qualification: AEC-Q200 rating supports use in vehicle electronics and other demanding environments.
• Defined ripple handling: Specified ripple currents at both low and high frequencies let designers size thermal and ripple budgets precisely.
• Long endurance at elevated temperature: 2000 hours at 85°C ensures predictable performance over extended operating life.
• Pick-and-place ready packaging: Embossed carrier taping simplifies automated assembly for volume production.
