UCH1V101MCL1GS

The UCH1V101MCL1GS is a chip-type, surface-mount aluminum electrolytic capacitor from Nichicon’s UCH series designed for high-reliability power filtering and decoupling. It combines a compact SMD can footprint with AEC-Q200 qualification, a wide operating temperature range of −40°C to 125°C, and low-temperature ESR characterization for demanding applications.

Key value comes from its durable specification set — 100 µF at 35 V, 2000 hours endurance at 125°C, and defined ripple current/ESR performance — enabling stable operation in thermally and electrically challenging environments.

Key Features

• Electrical Performance: Rated capacitance 100 µF with ±20% tolerance and rated voltage 35 V. Specified leakage current is ≤ 0.01CV (µA) after 2 minutes at 20°C.
• Low-temperature ESR: ESR characterized at low temperature with an added ESR specification after testing at −40°C; equivalent series resistance specified as 300 mΩ at 100 kHz.
• Ripple Current Ratings: Low- and high-frequency ripple capability specified — 98.5 mA at 120 Hz and 197 mA at 10 kHz — with frequency coefficients provided for broader frequency behavior.
• High-temperature Endurance: Endurance rating of 2000 hours at 125°C with defined limits for capacitance change (±30%), tan δ, and leakage current after test.
• Qualification & Compliance: AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting use in regulated and reliability-focused designs.
• Compact SMD Can Package: Chip-type SMD can with overall dimensions L: 7.7 × D: 6.3 mm and recommended land size 6.6 × 6.6 mm; suitable for automatic mounting using carrier tape.

Typical Applications

• Automotive Electronics: AEC-Q200 qualification and −40°C to 125°C rating make this capacitor suitable for control modules and power subsystems that require reliable filtering and energy smoothing under automotive temperature stress.
• Power Supply Filtering: Compact SMD can and defined ripple current/ESR values make it suitable for decoupling and bulk filtering in DC–DC converters and voltage regulation stages.
• Industrial and Embedded Systems: High-temperature endurance and stable low-temperature impedance support power management in industrial controllers and embedded boards operating across wide temperature ranges.

Unique Advantages

• Specified Low-temperature Behavior: ESR performance is explicitly specified after −40°C testing, reducing uncertainty for cold-start and low-temperature operation.
• Long-term High-temperature Stability: 2000 hours endurance at 125°C with defined limits ensures predictable life behavior in prolonged high-temperature environments.
• Defined Leakage and Dissipation: Clear leakage current limit (≤ 0.01CV after 2 minutes at 20°C) and tan δ specifications help with precise power-loss and leakage budgeting.
• Automated Assembly Ready: Designed for carrier-tape feeding and surface-mount placement to streamline high-volume manufacturing and reduce assembly risk.
• Compact Footprint: Small can dimensions and a recommended land pattern (6.6 × 6.6 mm) allow space-efficient board layouts without sacrificing capacitance.
