UUN2A470MNQ1MS

The UUN2A470MNQ1MS from Nichicon is a chip‑type, bi‑polarized aluminum electrolytic capacitor in the UUN series designed for surface mounting on high‑density PC boards. It provides a 47 µF capacitance at a 100 V rating with a compact radial can SMD package and is intended for general‑purpose circuitry that requires higher capacitance in a surface‑mount form factor.

Key value propositions include wide operating temperature capability (−55 °C to +105 °C), RoHS compliance, and suitability for automated assembly (carrier‑tape fed), making it a practical choice for robust, space‑conscious designs.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance with a 100 V rated voltage and a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Bi‑Polar Construction — Bi‑polarized design for operation without polarity constraints across the specified temperature range (−55 °C to +105 °C).
• Chip‑Type SMD Package — Radial, can‑style SMD package sized L: 1.65 × D: 1.6 cm with a recommended surface‑mount land size of 1.63 × 1.63 cm; compatible with automatic mounting machines fed with carrier tape.
• Endurance & Reliability — Rated endurance: 2000 hours at 105 °C with polarity inversion every 250 hours; leakage current specified as ≤0.03CV (µA) after 1 minute at 20 °C.
• Ripple Current Capability — Specified ripple current of 180 mA at 120 Hz and 360 mA at 10 kHz for this part; frequency coefficients provided in the series data for evaluating performance across frequencies.
• Series‑Level Stability — UUN series provides defined low‑temperature impedance characteristics and tan δ limits across rated voltages to support predictable behavior in a wide temperature range.
• RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose PCB Designs — Use where a bi‑polarized, higher‑capacitance SMD electrolytic is required for compact assemblies and general filtering or decoupling tasks.
• High‑Density Surface‑Mount Assemblies — Chip‑type radial can package optimized for automatic mounting on high‑density PC boards using carrier tape.
• Temperature‑Varied Environments — Circuits that require stable capacitor performance across −55 °C to +105 °C benefit from the UUN series endurance and stability specifications.

Unique Advantages

• High Voltage in a Compact SMD — 100 V rating paired with 47 µF capacitance provides higher energy storage capacity while maintaining a surface‑mount form factor.
• Bi‑Polar Flexibility — Non‑polarized operation simplifies placement in AC‑coupled or bidirectional signal paths and removes polarity constraints during layout.
• Assembly‑Ready Package — Designed for carrier‑tape feeding and automatic mounting machines to streamline high‑volume assembly processes.
• Predictable Endurance — Specified 2000 hour life at 105 °C with defined test conditions and leakage current limits supports lifecycle planning and reliability assessments.
• Frequency‑aware Ripple Ratings — Provided ripple current values and frequency coefficients enable accurate thermal and ripple sizing across application frequencies.
• Regulatory Compliance — RoHS compliance supports environmental and regulatory requirements for commercial products.
