UUG1H471MNJ6MS

The UUG1H471MNJ6MS is a Nichicon UUG series aluminum electrolytic, chip-type surface-mount capacitor offering 470 µF nominal capacitance at a 50 V rating. Designed for applications requiring higher capacitance in a compact SMD can, it provides durable performance across a −40°C to 85°C operating range with a rated endurance of 2000 hours at 85°C.

This part targets designs that need bulk energy storage and smoothing in compact, automated assemblies — delivering measurable ripple handling and controlled loss characteristics for reliable power conditioning.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Loss Tangent (tan δ) — Specified tan δ of 0.12 measured at 20°C and 120 Hz, providing a defined dissipation characteristic for predictable thermal and AC performance.
• Ripple Current Capability — Low-frequency ripple current of 740 mA at 120 Hz and high-frequency ripple current of 1.11 A at 10 kHz, enabling effective filtering across a range of ripple frequencies.
• Leakage Current — Measured leakage current listed at 705 µA (after 1 minute at 20°C), supporting design calculations for standby and bias currents.
• Endurance — Rated for 2000 hours at 85°C with defined limits: capacitance change within ±20% and tan δ up to 200% of initial value after endurance test.
• Chip SMD Can Package — φ12.5 × 21 mm can-style chip package for surface-mount assembly; packaged in embossed carrier tape for automated pick-and-place.
• AEC-Q200 Qualified — Built and rated to AEC-Q200 stress test standards, making it suitable for automotive electronic applications that require that level of qualification.

Typical Applications

• Automotive Electronics — Engine control modules, body electronics and other vehicle systems where AEC-Q200 qualification and a 50 V rating are required for reliable bulk capacitance and smoothing.
• Power Supply Filtering — Bulk smoothing and ripple reduction on mid-voltage rails where 470 µF at 50 V and defined ripple current performance help stabilize DC outputs.
• Compact SMD Power Modules — Integration into space-constrained, automated assemblies using the chip can SMD form factor and embossed carrier taping for efficient placement.

Unique Advantages

• High Capacitance in a Chip SMD Can — 470 µF in a φ12.5 × 21 mm package provides significant bulk capacitance without a through-hole form factor, reducing board real estate for high-capacity needs.
• Measured AC Performance — Specified tan δ (0.12 at 20°C/120 Hz) and documented ripple currents at multiple frequencies allow engineers to model thermal and AC losses precisely.
• Automotive-Grade Reliability — AEC-Q200 rating and a 2000-hour endurance at 85°C support use in demanding environments where validated stress performance matters.
• Assembly-Ready Packaging — Supplied in embossed carrier taping for automated pick-and-place, simplifying production flow and reducing handling time.
• Predictable Leakage Behavior — Provided leakage current specification (705 µA) enables accurate bias and quiescent current budgeting in system designs.
