UUG2A101MNQ1MS

The UUG2A101MNQ1MS is a surface-mount, polarized aluminum electrolytic capacitor from Nichicon's UUG series. It provides 100 µF capacitance at a 100 V rating in a compact chip-style can package designed for board-level power applications.

Engineered for demanding environments, this part combines a low dissipation factor (tanδ = 0.08 at 20°C, 120 Hz, 100 V) with defined ripple capability (440 mA at 120 Hz; 660 mA at 10 kHz) and a 2,000-hour endurance at 85°C. The device carries an AEC‑Q200 rating and is specified for automotive applications across a –40°C to 85°C operating range.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 100 V provides bulk energy storage and voltage handling in a single SMD component.
• Loss Characteristics — tanδ of 0.08 (measured at 20°C, 120 Hz, 100 V) for predictable AC loss and thermal behavior in filtering and decoupling roles.
• Ripple Current Performance — Rated ripple current of 440 mA at 120 Hz (low frequency) and 660 mA at 10 kHz (high frequency) to support both line-frequency and high-frequency switching environments.
• Leakage Current — Specified leakage current of 300 µA (typical measurement condition after 1 minute at 20°C) to help dimension bias and standby loss considerations.
• Endurance & Temperature — Life rating of 2,000 hours at 85°C with an operating temperature range from –40°C to 85°C.
• Package & Mounting — Chip-type radial can SMD in a φ12.5 × 16 mm package with embossed carrier taping for automated surface-mount assembly.
• Automotive Qualification — AEC‑Q200 rated and listed for automotive applications where industry qualification is required.

Typical Applications

• Automotive electronic modules — AEC‑Q200 rating and 100 V capability make this capacitor suitable for electronic control units and other automotive subsystems requiring reliable bulk capacitance.
• Board-level power subsystems — Use where compact, surface-mount bulk capacitance is needed to support power rails and intermediate bus voltages up to 100 V.
• Filtering and decoupling in high-voltage circuits — Provides ripple handling and energy buffering for circuits operating at elevated DC voltages with both low- and high-frequency content.

Unique Advantages

• High-voltage capability: 100 V rating allows deployment in elevated-voltage power rails without series stacking.
• Verified AC performance: Low tanδ (0.08 at 100 V, 120 Hz) supports predictable dissipation and thermal sizing in AC-loaded applications.
• Dual-frequency ripple support: Defined ripple current ratings at 120 Hz and 10 kHz allow specification across switching and line-frequency regimes.
• Automotive-grade qualification: AEC‑Q200 rating aligns the part to automotive program requirements for qualified components.
• Compact SMD form factor: φ12.5 × 16 mm chip can with embossed carrier taping streamlines SMT assembly while delivering higher capacitance than typical chip capacitors of similar footprint.
• Durability in elevated temperature: 2,000-hour endurance at 85°C supports long-term use in thermally stressed environments.
