UUR1A331MNL1GS

The UUR1A331MNL1GS is a chip-style aluminum electrolytic capacitor from the Nichicon UUR series, delivering high capacitance in a compact surface-mount can. It is designed for surface mounting on high-density PC boards and is compatible with automatic mounting machines fed with carrier tape.

This part provides 330 µF at a 10 V rating, polarized construction, RoHS compliance, and AEC-Q200 qualification for automotive use. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 10 V rated voltage, suitable where higher bulk capacitance is required in an SMD form factor.
• Capacitance Tolerance: ±20% tolerance at 120 Hz, 20°C for predictable design margins.
• Polarized Construction: Polar aluminum electrolytic design for DC power smoothing and bulk decoupling.
• Package & Mounting: Radial can SMD package optimized for surface-mount assembly and carrier-tape automatic placement.
• Automotive-Grade Reliability: AEC-Q200 rated and specified for automotive applications.
• Operating Temperature: Specified performance across −40°C to +85°C for broad environmental compatibility.
• Endurance: Rated for 2000 hours at 85°C with defined limits on capacitance change, tan δ, and leakage current after the test.
• Ripple Current Handling: 240 mA at 120 Hz and 312 mA at 10 kHz to support common power-conditioning demands.
• Compact Footprint: Physical size L: 1 × D: 0.8 cm for high capacitance density on space-constrained PCBs.
• Compliance: RoHS directive compliant for restricted substances requirements.

Typical Applications

• Automotive Electronics: Suited for automotive modules where AEC-Q200 qualification and bulk energy storage are required.
• High-density PCB Power Supply Decoupling: Provides bulk capacitance in compact SMD assemblies on space-limited boards.
• Automatic Assembly Lines: Carrier-tape compatible package designed for automated surface-mount placement processes.

Unique Advantages
