UUX1A101MCL1GS

The UUX1A101MCL1GS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UUX series. It is a chip-type, polarized capacitor offering 100 µF capacitance at a 10 V rating and designed for wide temperature operation.

Engineered for demanding environments, this part targets automotive and other robust electronics applications that require compact smoothing and decoupling with defined ripple handling and endurance over a wide temperature range.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 10 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Wide Temperature Range — Operating range from -55°C to +105°C, supporting designs exposed to extended temperature extremes.
• Endurance — Rated life of 2000 hours at 105°C, with capacitance change within ±20% after specified endurance testing.
• Low Loss (tan δ) — tan δ of 0.19 (max) at 20°C, 120 Hz for the 10 V rating, supporting predictable AC performance at line frequencies.
• Ripple Current Capability — Low-frequency ripple current of 90 mA at 120 Hz and high-frequency ripple current of 117 mA at 10 kHz, enabling effective smoothing across frequency ranges.
• Leakage Current — Specified leakage current of 30 µA (I ≤ 0.03CV after 1 minute’s application of rated voltage at 20°C for 6.3–100 V ratings).
• Compact SMD Can — Case size φ8 × 6.2 mm (length 6.2 mm, diameter 8 mm) in a radial can-style SMD package; recommended land pattern 8.3 × 8.3 mm.
• Packaging — Supplied in embossed carrier taping for automated surface-mount assembly.
• AEC‑Q200 Rated — Series-level AEC‑Q200 rating indicated in the product data, supporting automotive-grade qualification requirements.

Typical Applications

• Automotive electronics — Suitable for automotive onboard power systems where AEC‑Q200 qualification and wide operating temperature are required.
• Power-rail smoothing — 100 µF capacitance and defined ripple current ratings provide bulk smoothing for low-voltage DC rails in compact designs.
• Decoupling in compact modules — Small φ8 × 6.2 mm SMD can helps conserve board space while providing polarized bulk decoupling at 10 V systems.
• High-temperature applications — Designed for sustained operation at elevated temperature (2000 h at 105°C), suitable where long-term stability under heat is needed.

Unique Advantages

• Automotive-capable qualification: AEC‑Q200 rating at the series level supports use in automotive-grade designs and engineering qualification flows.
• Wide temperature tolerance: -55°C to +105°C operation enables deployment in environments with significant thermal variation.
• Defined endurance specification: 2000 hours at 105°C gives designers a clear lifetime expectation for reliability planning.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz make performance predictable across both low- and high-frequency noise sources.
• Compact SMD form factor: φ8 × 6.2 mm package and embossed carrier taping simplify placement in automated assembly while minimizing board area.
