UCM1C681MNS1GS

The UCM1C681MNS1GS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. With 680 µF capacitance at a 16 V rating, this SMD can provides bulk energy storage and filtering in compact board layouts.

Engineered for demanding environments, the capacitor supports an operating temperature range of −55 °C to 105 °C, AEC‑Q200 qualification, embossed carrier taping for automated placement, and vibration-resistant construction for robust field performance.

Key Features

• Capacitance & tolerance — 680 µF with ±20% tolerance (120 Hz, 20 °C), suitable for high-capacitance SMD requirements.
• Rated voltage & polarity — 16 V rated, polarized design for DC power applications.
• Low impedance performance — Chip-type low-impedance construction optimized for reduced ESR behavior in decoupling and smoothing roles.
• Ripple current capability — 425 mA at 120 Hz (low frequency) and 850 mA at 10 kHz (high frequency) to handle real-world switching and supply ripple.
• Leakage current — Specified leakage current: 108.8 µA after rated voltage application (per product data).
• Temperature & endurance — Operating −55 °C to 105 °C with a rated life of 2000 hours at 105 °C (endurance condition for φD ≤ 10).
• Package & mounting — Surface-mount radial can (chip type) in φ8 × 10L size (L: 1.0 cm × D: 0.8 cm) with recommended land pattern 8.3 × 8.3 mm; supplied in embossed carrier tape for automatic placement.
• Reliability features — Vibration-resistant construction and AEC‑Q200 qualification noted for applications requiring automotive-grade robustness.
• Environmental compliance — RoHS compliant.

Typical Applications

• Automotive power systems — Bulk decoupling and smoothing on 12 V and auxiliary rails where AEC‑Q200 qualification and wide temperature range are required.
• DC–DC converters — Input/output filtering for converters that demand high ripple current capability at both low and high frequencies.
• Embedded power boards — Compact SMD energy storage for on-board power stabilization in space-constrained assemblies.

Unique Advantages

• High ripple handling: Specified 425 mA (120 Hz) and 850 mA (10 kHz) ratings support both low- and high-frequency ripple demands.
• Wide temperature endurance: −55 °C to 105 °C operating range and 2000-hour life at 105 °C for sustained performance in harsh thermal environments.
• Automotive-ready qualification: AEC‑Q200 rating aligns the part with automotive development and qualification flows.
• Automated assembly friendly: Embossed carrier taping and chip-type SMD can package enable efficient pick-and-place mounting.
• Compact footprint: φ8 × 10L package with an 8.3 × 8.3 mm recommended land pattern yields high capacitance in a small board area.
• Vibration resistance: Mechanical robustness suitable for applications where vibration tolerance is required.
