UWT1A101MCL1GB

The UWT1A101MCL1GB is a Nichicon UWT series aluminum electrolytic chip-type capacitor designed for surface-mount assemblies. It provides 100 µF capacitance at a 10 V rating in a compact SMD radial-can package optimized for high-density printed circuit boards.

Engineered for demanding temperature and production environments, this part offers a wide operating temperature range (−55 to +105°C), AEC-Q200 qualification, RoHS compliance, and compatibility with tape-fed automatic mounting machines—making it suitable for automotive and other assembly-driven applications requiring reliable, compact bulk capacitance.

Key Features

• Core electrical specification — 100 µF capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Wide operating temperature — Rated for −55°C to +105°C to support designs that encounter extreme ambient conditions.
• High-temperature endurance — Specified lifetime of 1000 hours at 105°C with endurance limits: capacitance within ±25% for 16 V or less (applies to this 10 V device), tan δ and leakage current within specified limits after test.
• Automotive-grade qualification — AEC-Q200 Qualified, supporting use in automotive-rated designs.
• Surface-mount, tape-fed compatible — Chip-type radial can SMD package designed for automatic mounting machines fed with carrier tape; surface-mount land size L: 6.6 mm × W: 6.6 mm.
• Compact package dimensions — Body size L: 5.4 mm × D: 6.3 mm for space-constrained PCB layouts.
• Ripple current specification — 60 mA at 120 Hz and 90 mA at 100 kHz to support smoothing and decoupling on DC rails.
• Leakage current specification — After 2 minutes’ application of rated voltage at 20°C, leakage current ≤ 0.01CV or 3 µA, whichever is greater.
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Bulk capacitance and decoupling in control modules and electronic subsystems where AEC-Q200 qualification and wide temperature range are required.
• High-density PCB power rails — Compact SMD footprint and 100 µF capacitance make it suitable for smoothing and local energy storage on compact boards.
• Automated surface-mount production — Designed for tape-fed automatic placement to streamline high-volume assembly and reduce manual handling.

Unique Advantages

• Wide temperature capability — Operates across −55°C to +105°C to accommodate harsh and varied thermal environments.
• Automotive-ready qualification — AEC-Q200 qualification provides confidence for automotive-grade system integration.
• Compact SMD form factor — Small L × D footprint (5.4 × 6.3 mm) conserves board area while delivering 100 µF capacitance.
• Production-friendly packaging — Tape-fed compatibility supports automated placement for consistent, high-throughput manufacturing.
• Documented endurance — 1000 hours at 105°C with defined acceptance criteria for capacitance change, tan δ, and leakage current to support reliable long-term performance.
• Clear electrical limits — Specified ripple currents and leakage current formula (≤ 0.01CV or 3 µA after 2 minutes) simplify thermal and reliability planning.
