UUN1V331MNQ1MS

The UUN1V331MNQ1MS is a chip‑type, bi‑polar aluminum electrolytic capacitor designed for surface mounting on high‑density PC boards. It delivers 330 µF at 35 V in a radial can SMD package and is intended for general‑purpose electronic applications requiring bipolar operation across a wide temperature range.

Engineered for automated assembly, the part is compatible with carrier‑tape feeding and is RoHS compliant. Its electrical and environmental specifications target reliability in applications that demand stability from -55 to +105°C.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 35 V, with tolerance ±20% (measured at 120 Hz, 20°C).
• Bi‑Polar Construction — Bi‑polarized design enables operation without polarity constraints across the specified temperature range.
• Temperature Range — Operational from -55°C to +105°C, suitable for designs that require wide ambient tolerance.
• Endurance — Rated for 2000 hours at 105°C with polarity inversion every 250 hours; capacitance change within ±20% and leakage current remains within initial specification after endurance testing.
• Leakage and Loss Characteristics — Leakage current specified as not more than 0.03 × C × V (µA) after 1 minute at 20°C; tangent of loss angle (tan δ) for 35 V is specified (max. 0.14 at 120 Hz, 20°C).
• Ripple Current Performance — Rated ripple current listed as 450 mA at 120 Hz and 675 mA at 10 kHz for this capacitance and case size; frequency coefficients for ripple current are provided in the series datasheet.
• Package & Mounting — Radial can SMD chip type sized L: 1.65 cm × D: 1.8 cm with a recommended surface‑mount land size of 1.83 × 1.83 cm; designed for automatic mounting via carrier tape.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• General Purpose Electronics — Acts as a compact energy storage and decoupling element in a wide range of consumer and industrial assemblies.
• High‑Density Surface‑Mount Assemblies — Designed for surface mounting on high‑density PC boards where board real estate and automated placement are priorities.
• Circuits Requiring Bipolar Operation — Suitable for circuits that need non‑polar capacitor behavior across the specified temperature range.

Unique Advantages

• High Capacitance in a Compact SMD Can — 330 µF in a chip‑type radial can provides notable capacitance for designs limited by board area.
• Bipolar Flexibility — Bi‑polarized construction removes polarity constraints, simplifying design in AC‑coupled or bidirectional circuits.
• Wide Operating Temperature — Rated for -55°C to +105°C to support applications exposed to broad temperature extremes.
• Proven Endurance at Elevated Temperature — 2000 hours at 105°C with defined limits on capacitance change and leakage supports long‑term stability in hot environments.
• Assembly‑Friendly — Compatible with carrier‑tape automatic mounting to streamline volume manufacturing and placement.
• RoHS Compliant — Meets current RoHS requirements for lead‑free assembly and environmental compliance.
