The UUR1C681MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UUR series, offering a high capacitance density in a surface-mount radial can package. It is designed for high-density PC boards and is compatible with automatic mounting machines fed with carrier tape.

With a rated capacitance of 680 µF at 16 V, AEC-Q200 compliance, RoHS conformity, and an operating temperature range of -40°C to +85°C, this part addresses demanding embedded and automotive electronic power applications that require compact energy storage and reliable performance.

Key Features

• Capacitance & Voltage: 680 µF rated capacitance at 16 V with ±20% tolerance (120 Hz, 20°C), suitable for bulk decoupling and smoothing in low-voltage power rails.
• Chip Type, High CV: Chip-type construction optimized for higher capacitance in a compact SMD form factor, enabling reduced board area for energy storage.
• Surface-Mount Compatibility: Designed for surface mounting on high-density PC boards and applicable to automatic mounting machines fed with carrier tape for efficient assembly.
• Package & Polarity: Radial, can-style SMD package (L: 1 × D: 1 cm) with polarized configuration for correct orientation in circuit designs.
• Electrical Performance: Ripple current ratings of 396 mA at 120 Hz and 514.8 mA at 10 kHz; tan δ at 16 V is specified (0.20 max), and leakage current specified as not more than 0.03CV (μA) after 1 minute at 20°C.
• Reliability & Endurance: AEC-Q200 compliant with endurance specified as 2000 hours at 85°C under rated voltage; after the test, capacitance change remains within ±20%, tan δ within 200% of initial spec, and leakage current within initial limits.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulatory requirements for lead-free assembly.

Typical Applications

• Automotive Electronics: Suitable for use in automotive modules where AEC-Q200 qualification and specified ripple current capability are required for power smoothing and decoupling.
• High-Density Surface-Mount Assemblies: Designed for compact PCBs and automatic tape-fed mounting processes, making it appropriate for space-constrained, automated production environments.
• Power Management Modules: Acts as a bulk energy storage and output filter component in low-voltage power supply designs, leveraging its 680 µF capacitance and defined ripple ratings.

Unique Advantages

• High Capacitance in a Compact SMD Can: 680 µF in a 1 × 1 cm footprint reduces board area for bulk capacitance compared to larger through-hole options.
• Assembly-Friendly Design: Chip-type construction and carrier-tape compatibility streamline automated placement for high-volume manufacturing.
• Qualification for Demanding Environments: AEC-Q200 compliance provides an added level of reliability appropriate for automotive and industrial applications.
• Verified Endurance: Endurance rating of 2000 hours at 85°C under rated voltage with defined post-test limits for capacitance, tan δ, and leakage current supports predictable long-term behavior.
• Clear Electrical Specs: Published ripple current values at 120 Hz and 10 kHz, along with leakage current and tan δ figures, make performance trade-offs straightforward during design.
• Regulatory Compliance: RoHS conformity supports modern lead-free production requirements.
