UUN1H471MNQ6MS

The UUN1H471MNQ6MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor in the Nichicon UUN series, specified at 470 µF and 50 V. It is designed for surface mounting on high‑density PC boards and for general‑purpose electronic applications that require higher capacitance in an SMD radial can package.

Key attributes include bi‑polarized construction, a wide operating temperature range of −55 to +105 °C, RoHS compliance, and an endurance rating of 2000 hours at 105 °C. The part is compatible with automated mounting processes using carrier tape.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 50 V, with capacitance tolerance ±20% (at 120 Hz, 20 °C).
• Bi‑Polarized Design — Specified as a bi‑polarized series and covered by endurance testing that includes polarity inversion during life testing.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C, suitable for designs requiring broad thermal performance.
• Endurance & Reliability — Endurance specified as 2000 hours at 105 °C with performance criteria for capacitance change, tan δ and leakage current after the test.
• Ripple Current Capability — Ripple current ratings of 640 mA at 120 Hz and 960 mA at 10 kHz (frequency dependence provided in the series data).
• Surface‑Mount Package — Chip/radial can SMD package designed for high‑density PC boards; compatible with automatic mounting using carrier tape. Recommended land size L: 1.83 × W: 1.83 cm.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Filtering — Bulk capacitance and 50 V rating make it suitable for smoothing and decoupling in general‑purpose electronic circuits requiring high capacitance.
• High‑Density PCB Assemblies — Chip‑type SMD radial can is designed for placement on high‑density boards where board area and automated placement are priorities.
• Automated SMT Production — Compatible with carrier tape feeding for automatic mounting machines, streamlining assembly for volume production.
• Wide‑Temperature Environments — Use in equipment that must operate across −55 °C to +105 °C while meeting endurance and leakage specifications.

Unique Advantages

• Higher Capacitance in SMD Form — Delivers 470 µF in a chip‑type radial can, enabling higher bulk capacitance while maintaining surface‑mount compatibility.
• Bi‑Polarized Series Design — Specified as bi‑polarized and validated through endurance testing that includes polarity inversion, supporting broader application scenarios.
• Validated Endurance — 2000 hours at 105 °C endurance test with defined limits for capacitance change, tan δ increase and leakage current, providing measurable reliability data.
• Defined Ripple Performance — Published ripple current values (640 mA at 120 Hz; 960 mA at 10 kHz) and frequency coefficients in the series data allow designers to size for expected AC stress.
• SMT‑Friendly Packaging — Designed for automatic mounting with carrier tape and specified land size, reducing integration effort on high‑density PCBs.
• Regulatory Compliance — RoHS compliant per the provided directive references.
