UUN1V471MNQ1MS

The UUN1V471MNQ1MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor from Nichicon’s UUN series, offering 470 µF capacitance at a 35 V rating in a surface‑mount radial can package. It is designed for use on high‑density printed circuit boards where compact, higher‑capacitance SMD solutions are required.

Key attributes include bi‑polar construction for polarity‑flexible circuits, a wide operating temperature range of −55°C to +105°C, and RoHS compliance—making it suitable for general‑purpose board‑level power and signal applications that demand durability across a broad temperature range.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with a 35 V rated voltage and tolerance of −20% to +20%, providing stable bulk capacitance for board‑level filtering and energy storage.
• Bi‑Polar Construction — Bi‑polarized design supports applications where polarity reversal may occur; part of the UUN bi‑polar series intended for such operating conditions.
• Wide Temperature Range — Specified for operation from −55°C to +105°C to support designs exposed to extreme ambient conditions.
• Endurance — Rated for 2000 hours at 105°C with polarity inversion every 250 hours, meeting the UUN series endurance criteria for long‑term thermal stress.
• Ripple Performance — Rated ripple current of 590 mA at 120 Hz and 885 mA at 10 kHz, with frequency coefficients defined by the UUN series for accurate ripple handling across frequencies.
• Leakage and Dissipation — Series specification for leakage current: after 1 minute’s application of rated voltage at 20°C, leakage ≤ 0.03 C·V (µA); specified tan δ limits apply per rated voltage (e.g., 0.14 max at 35 V, measured at 120 Hz, 20°C).
• Surface‑Mount Package — Chip radial can SMD package designed for automatic mounting with carrier tape; package case type listed as radial, can – SMD with board land size provided for assembly layout.
• Physical Size — Size dimensions: L: 2.15 × D: 1.8 cm; recommended surface mount land size: L: 1.83 × W: 1.83 cm.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑density PCB designs — Surface‑mount chip form factor suits compact board layouts that require higher capacitance in limited footprint areas.
• Bipolar circuits — Bi‑polarized construction supports circuits where polarity may reverse or where non‑polar capacitors are required.
• General‑purpose power conditioning — Bulk smoothing and decoupling on power rails within the specified voltage and ripple current limits.
• Industrial and commercial electronics — Useful in equipment that operates across a wide temperature range thanks to the −55°C to +105°C rating and 2000 h endurance at 105°C.

Unique Advantages

• Higher capacitance in an SMD chip — 470 µF nominal value in a chip‑type radial can package provides substantial bulk capacitance while maintaining a surface‑mount footprint.
• Polarity flexibility — Bi‑polar design reduces constraints on circuit orientation and supports applications where polarity reversal can occur.
• Temperature and endurance specification — Rated for −55°C to +105°C and 2000 hours at 105°C (with polarity inversion), offering predictable performance over extended thermal exposure.
• Measurable ripple capability — Defined ripple current ratings at 120 Hz and 10 kHz enable designers to size capacitors with respect to expected AC stress.
• Assembly‑ready surface‑mount format — Compatible with automated mounting via carrier tape and provided land size dimensions simplify PCB layout and assembly planning.
• Regulatory compliance — RoHS compliance supports designs targeting regulated markets and environmental requirements.
