UCM1E512MNS1MS

The UCM1E512MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 5100 µF capacitance at a 25 V rating in a compact φ18 × 21.5 mm can, and is supplied on embossed carrier taping for automated placement.

Targeted for demanding environments, this part offers high ripple-current capability, wide operating temperature range (−55°C to +105°C), vibration resistance and AEC-Q200 qualification, making it suitable for robust power filtering and energy-storage roles in automotive and similarly rigorous applications. Status: Mass Production.

Key Features

• Electrical Capacity — 5100 µF nominal capacitance with ±20% tolerance, providing substantial bulk energy storage for power-rail smoothing.
• Rated Voltage — 25 V rated voltage suitable for common automotive and industrial low-voltage power rails.
• Low Impedance & Ripple Handling — Low-impedance chip design with specified ripple currents of 1.32 A at 120 Hz and 2.64 A at 10 kHz to support both low- and high-frequency filtering.
• Thermal Endurance — Operates across −55°C to +105°C with an endurance rating of 5000 hours at 105°C, supporting prolonged operation in high-temperature environments.
• Leakage & Loss Characteristics — Leakage current specified at 1275 µA and tanδ (DF) of 0.22 measured at 20°C, 120 Hz, providing predictable loss and standby behavior.
• Package & Assembly — Chip-type radial can for surface mount with embossed carrier taping, enabling automatic pick-and-place and reflow-compatible assembly processes.
• Robustness & Compliance — Vibration-resistant construction and AEC-Q200 qualification, with RoHS compliance for environmental requirements.

Typical Applications

• Automotive power rails — Bulk smoothing and decoupling in automotive electronic modules where high ripple current and wide temperature range are required.
• Power conversion — Energy storage and output filtering for DC–DC converters and voltage regulators that encounter both low- and high-frequency ripple.
• Control and ECU modules — Long-life capacitor solution for electronic control units requiring endurance at elevated ambient temperatures and vibration resistance.

Unique Advantages

• High capacitance in a compact SMD can — 5100 µF in a φ18 × 21.5 mm package delivers significant bulk storage while remaining compatible with automated surface-mount processes.
• Designed for high ripple environments — Specified ripple currents (1.32 A @120 Hz, 2.64 A @10 kHz) mean the part can handle demanding AC ripple and switching-noise conditions.
• Wide temperature and long endurance — −55°C to +105°C operating range and 5000-hour life at 105°C provide predictable performance in harsh thermal conditions.
• AEC-Q200 qualified and vibration resistant — Built for reliability in automotive-class systems where mechanical and environmental robustness are required.
• Manufacturing-ready packaging — Embossed carrier taping simplifies automated placement and throughput for volume production lines.
• Regulatory compliance — RoHS-compliant construction supports environmental and regulatory requirements for modern electronics programs.
