UUJ1C471MNJ1MS

The UUJ1C471MNJ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UUJ series, offering high capacitance in a chip-type SMD can (φ12.5 × 13.5 mm). It is designed for high-density PCBs and automated assembly, targeting applications that require robust bulk capacitance, long-term endurance and automotive-grade qualification.

Key value propositions include a rated capacitance of 470 µF at 16 V, long endurance (5000 hours at 105°C), and compatibility with embossed carrier taping for pick-and-place production environments.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a rated voltage of 16 V and a capacitance tolerance of ±20% (120 Hz, 20°C).
• Low-loss Performance: Tangent of loss angle (tan δ) 0.18 measured at 20°C, 120 Hz, supporting stable AC performance for smoothing and energy storage functions.
• Ripple Current Handling: Built to handle 360 mA at 120 Hz (low frequency) and 540 mA at 10 kHz (high frequency), enabling effective ripple filtering across a range of operating frequencies.
• Leakage Current: Specified leakage current of 225.6 µA, suitable for many power-supply reservoir and decoupling applications where low steady-state leakage is required.
• Reliability & Endurance: Endurance specified at 5000 hours with rated voltage applied at 105°C; capacitors meet the documented endurance limits for capacitance change, tan δ and leakage current.
• Automotive-Grade Qualification: AEC-Q200 rated, supporting use in automotive electronics and other applications requiring component-level automotive qualification.
• Operating Temperature Range: −55°C to +105°C, suitable for wide temperature environments encountered in embedded and vehicle electronics.
• Package & Assembly: Radial can SMD (chip type) in a φ12.5 × 13.5 mm size, supplied in embossed carrier tape for automated mounting; recommended land size L: 1.28 × W: 1.28 cm.
• RoHS Compliance: Compliant with RoHS requirements for restricted substances.

Typical Applications

• Automotive systems: Bulk energy storage and smoothing in vehicle electronic modules, leveraging AEC-Q200 qualification and 5000-hour endurance at 105°C.
• High-density PCB power rails: Surface-mount chip-type construction provides high capacitance in a compact footprint for space-constrained power-supply sections.
• Automated assembly lines: Supplied in embossed carrier tape and compatible with automatic mounting machines for efficient pick-and-place production.

Unique Advantages

• High capacitance in a compact SMD can: 470 µF in a φ12.5 × 13.5 mm package reduces board area compared with larger through-hole capacitors.
• Endurance at elevated temperature: 5000 hours at 105°C provides long-term stability for designs that operate in hot environments.
• Frequency-flexible ripple capability: Specified ripple current at both 120 Hz and 10 kHz supports filtering across low and high frequency domains.
• Automotive-qualified reliability: AEC-Q200 rating gives designers confidence for use in vehicle electronics and other regulated applications.
• Manufacturing-ready packaging: Embossed carrier taping enables seamless integration into automated PCB assembly processes.
• Regulatory compliance: RoHS compliance simplifies use in regulated supply chains and product rollouts.
