UCM1C681MNL1GS

The UCM1C681MNL1GS is a chip-type aluminum electrolytic capacitor in a surface-mount radial can package designed for low impedance performance. It delivers 680 µF at 16 V with characteristics targeted at power electronics and automotive applications where compact bulk capacitance, temperature stability and automated assembly are required.

Key attributes include AEC-Q200 qualification, a wide operating temperature range of −55°C to 105°C, and a 2000‑hour endurance rating at 105°C, making it suitable for systems that demand robust performance across temperature and lifetime stress conditions.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 16 V and a tolerance of −20% to +20%.
• Low Loss / Low Impedance — tanδ (DF) specified at 0.16 (measured at 20°C, 120 Hz), supporting applications that benefit from reduced ESR and improved ripple handling.
• Ripple Current Capability — Low-frequency ripple current of 425 mA (120 Hz) and high-frequency ripple current of 850 mA (100 kHz) for effective smoothing and filtering under dynamic loads.
• Leakage Current — Specified leakage current of 108.8 µA under rated conditions for predictable standby and quiescent behavior.
• Temperature & Endurance — Rated for −55°C to 105°C operation with a life endurance of 2000 hours at 105°C (capacitors with φD ≤ 10 mm follow the specified endurance condition).
• Surface-Mount Package — Compact φ8 × 10 L can in an SMD radial package with recommended land size 8.3 × 8.3 mm; supplied in embossed carrier taping for automated pick-and-place.
• Compliance & Qualification — RoHS compliant and AEC‑Q200 listed in the product specifications for applications requiring industry-recognized component qualification.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and a −55°C to 105°C rating suit ECU power rails and other automotive modules that require qualified SMD bulk capacitance at 16 V.
• DC–DC converters and power rails — High-frequency ripple current rating (850 mA at 100 kHz) and 680 µF capacitance provide effective smoothing and decoupling on board-level converters and regulators.
• SMD board-level energy storage — Compact φ8×10L footprint and embossed carrier taping enable automated assembly of bulk capacitors on densely populated PCBs.

Unique Advantages

• AEC‑Q200 qualification: Provides an added level of component qualification for designs targeting automotive or similarly demanding environments.
• Wide operating temperature range: −55°C to 105°C supports reliable operation across harsh thermal conditions.
• High ripple handling: Dual-rated ripple current (425 mA at 120 Hz, 850 mA at 100 kHz) helps maintain voltage stability under varying load frequencies.
• Long high-temperature endurance: 2000 hours at 105°C demonstrates sustained performance for long-term thermal stress.
• Automated assembly ready: Embossed carrier taping and compact SMD form factor simplify integration into high-volume manufacturing flows.
• Regulatory compliance: RoHS compliance supports use in regulated markets and designs requiring restricted substance conformance.
