UUR1C471MNL1GS

The UUR1C471MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UUR series, offering high capacitance in a compact surface-mount form. It is designed for dense PCB layouts and automated assembly, and is provided as an SMD radial can for integration into space-constrained designs.

Key attributes include 470 µF capacitance at 16 V, AEC-Q200 compliance, RoHS conformity, and rated performance across an operating range of -40 °C to 85 °C—making it suitable for applications that require rugged, board-mounted bulk capacitance solutions.

Key Features

• High Capacitance: 470 µF nominal capacitance provides bulk energy storage and filtering capacity in a compact chip form.
• Rated Voltage: 16 V rating suitable for low-voltage power rails and decoupling applications that require higher CV in a small footprint.
• Tolerance & Polarization: Capacitance tolerance ±20% and polarized construction—clear design expectations for circuit integration.
• Package & Mounting: Radial, can-style SMD package designed for surface mounting on high-density PCBs and compatible with carrier-tape automated mounting.
• Temperature & Endurance: Operating range -40 °C to 85 °C with endurance specified for 2000 hours at 85 °C; capacitance change remains within ±20% after the endurance test.
• Ripple Performance: Ripple current ratings of 330 mA at 120 Hz and 429 mA at 10 kHz, supporting both low- and high-frequency ripple environments.
• Leakage Current (series spec): Leakage current specified as not more than 0.03CV (µA) after 1 minute at 20 °C, per series datasheet guidelines.
• Compliance: AEC-Q200 qualified and RoHS compliant, aligning with regulated manufacturing and reliability requirements.
• Compact Footprint: Physical size approximately L: 1 × D: 1 cm for integration in space-constrained assemblies.

Typical Applications

• Automotive systems: AEC-Q200 qualification and robust endurance make this capacitor suitable for automotive electronic modules requiring board-mounted bulk capacitance.
• High-density surface-mount PCBs: Chip-type SMD can for designs where board space is limited and higher capacitance is required.
• Automated assembly lines: Designed for compatibility with carrier-tape feeding and automatic mounting machines, streamlining high-volume production.
• RoHS-compliant product lines: Suitable for applications and product families that require RoHS (2011/65/EU, (EU)2015/863) compliance.

Unique Advantages

• High CV in a compact SMD form: 470 µF at 16 V delivers substantial energy storage while minimizing PCB area compared with larger through-hole alternatives.
• Automated assembly ready: Carrier-tape compatibility and SMD package reduce pick-and-place integration complexity and speed production.
• Designed for reliability: AEC-Q200 compliance and specified endurance (2000 h at 85 °C) provide predictable performance under elevated temperature stress.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz support mixed-frequency power environments commonly found in power-conversion and control electronics.
• Clear electrical expectations: Series leakage current and tan δ characteristics are defined in the datasheet, supporting accurate design margining and thermal management.
