UUR1A681MNL1GS

The UUR1A681MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UUR series, designed to deliver high capacitance in a compact surface-mount package for high-density PCBs. Its 680 µF capacitance at a 10 V rating and chip-style SMD can supports bulk decoupling and energy storage where board area is limited.

This part is AEC-Q200 compliant and specified for automotive applications, RoHS compliant, and configured for carrier-tape automatic mounting. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• High Capacitance (680 µF): Provides substantial bulk energy storage for smoothing, decoupling and power-conditioning applications on compact PCBs.
• Rated Voltage — 10 V: Suited to low-voltage power rails and DC-DC converter output filtering.
• Chip-Type Surface-Mount Package: Radial, can-style SMD package engineered for high-density board layouts and automated mounting from carrier tape.
• Automated Assembly Friendly: Applicable to automatic mounting machines fed with carrier tape for consistent high-volume placement.
• Automotive-Grade Reliability: AEC-Q200 compliant with an operating temperature range of −40°C to +85°C, supporting automotive electronics use cases.
• Durability and Lifetime: Rated endurance of 2000 hours at 85°C with capacitance change within ±20% after endurance testing.
• Ripple Current Performance: Specified ripple handling of 374 mA at 120 Hz and 486.2 mA at 10 kHz for AC/stressed conditions.
• Tight Leakage and Loss Characteristics: Series leakage spec (≤0.03CV μA after 1 minute at 20°C) and defined tan δ values at 120 Hz support predictable behavior in designs.
• RoHS Compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics: Bulk decoupling and energy storage in control modules and power management circuits where AEC-Q200 compliance and −40°C to +85°C operation are required.
• Power Supply Filtering: Smoothing and output filtering for DC-DC converters and low-voltage regulators on compact boards.
• High-Density PCB Designs: Compact chip-type form factor enables high capacitance placement on space-constrained board layouts.

Unique Advantages

• High CV in a Chip Package: 680 µF at 10 V delivers bulk capacitance without large through-hole components, saving PCB space and simplifying layout.
• Automated Production Ready: Carrier-tape compatibility and SMD can-style package streamline pick-and-place assembly for volume manufacturing.
• Automotive Qualification: AEC-Q200 compliance and a −40°C to +85°C operating range provide traceable suitability for automotive-grade designs.
• Defined Endurance and Thermal Limits: 2000 hours at 85°C endurance rating with specified limits for capacitance, tan δ and leakage supports predictable life-cycle planning.
• Measured Ripple Capability: Published ripple current values at 120 Hz and 10 kHz help engineers size capacitors against real-world AC stress conditions.
