UCL1E100MCL1GS

The UCL1E100MCL1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount radial can package. It provides 10 µF capacitance at a 25 V rating with electrical characteristics tailored for demanding temperature and ripple conditions.

Designed for automotive and other high-reliability electronics, this Nichicon UCL series part combines low loss (tanδ 0.14 at 20°C, 120 Hz), low leakage (3 µA), and specified ripple performance to support power filtering and decoupling in compact SMD assemblies.

Key Features

• Capacitance & Tolerance — 10 µF nominal with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 25 V working voltage suitable for many low-voltage power rails.
• Low Loss / Low Impedance — tanδ (DF) = 0.14 at 20°C, 120 Hz and specified impedance of 850 mOhm for improved AC performance.
• Ripple Current Capability — Supports 80 mA at 120 Hz (low frequency) and 160 mA at 10 kHz (high frequency) for effective ripple handling.
• Leakage Current — Maximum leakage current specified at 3 µA after 2 minutes at rated voltage and 20°C.
• Robust Temperature & Endurance — Operational range −55°C to +105°C with endurance specified as 2000 hours at 105°C under rated voltage.
• Package & Mounting — Chip-type radial can SMD, size φ4 × 5.8 mm with recommended land size 4.3 × 4.3 mm; supplied on embossed carrier taping for automated placement.
• Automotive-Grade Reliability — Rated to AEC-Q200, suitable for designs requiring that qualification.

Typical Applications

• Automotive electronics — Filtering and smoothing of power rails in control modules where AEC-Q200 qualification and wide temperature range are required.
• On-board power filtering — Local decoupling and ripple reduction on PCB power networks, supported by specified low- and high-frequency ripple current ratings.
• Compact SMD power assemblies — Small chip-type radial can form factor for space-constrained surface-mount applications that need stable capacitance across temperature.

Unique Advantages

• Low-impedance chip design — Provides better AC performance and ripple handling compared to higher-impedance alternatives, aiding stable power delivery.
• AEC-Q200 rated — Meets automotive component qualification requirements for designs that require industry-recognized reliability standards.
• Wide operating temperature — −55°C to +105°C rating supports deployment in harsh thermal environments common in automotive and industrial equipment.
• Long endurance at elevated temperature — 2000 hours at 105°C under rated voltage helps ensure long-term stability in high-temperature applications.
• Small footprint with automated assembly — φ4 × 5.8 mm SMD can and embossed carrier taping minimize PCB space and support high-volume pick-and-place processes.
• Low leakage current — 3 µA maximum leakage reduces standby losses and helps maintain performance in low-current circuits.
