UUN1V331MNQ6MS

The UUN1V331MNQ6MS is a chip-type, bi-polarized aluminum electrolytic capacitor from Nichicon's UUN series, engineered for surface mounting on high-density printed circuit boards. It provides a higher capacitance option within the series and is specified as a general-purpose surface-mount component.

Key technical attributes include a capacitance of 330 µF at 35 V, bipolar construction for non-polarized applications, compatibility with automatic carrier-tape mounting, a wide operating temperature range of -55°C to +105°C, and RoHS compliance.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 35 V provides substantial bulk capacitance in a compact SMD package.
• Bi-Polar Construction — Bi-polarized design enables use in circuits where polarity reversal may occur; specified series behavior over the full temperature range of -55°C to +105°C.
• Package & Mounting — Chip-type radial can configured for surface-mount applications; package footprint dimensions L: 2.15 × D: 1.6 cm with recommended land size L: 1.63 × W: 1.63 cm. Applicable to automatic mounting machines fed with carrier tape.
• Temperature & Endurance — Rated to operate from -55°C to +105°C with an endurance specification of 2000 hours at 105°C (with polarity inversion per the series specification).
• Electrical Performance — Capacitance tolerance ±20%; ripple current ratings of 450 mA at 120 Hz and 675 mA at 10 kHz provide defined AC handling capability for decoupling and smoothing tasks in continuous operation.
• Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics — Intended for use in general-purpose circuits where a bi-polar aluminum electrolytic capacitor is required.
• High-density PC boards — Designed specifically for surface mounting on high-density printed circuit boards.
• Automated assembly — Compatible with carrier-tape feeding for automatic mounting machines, simplifying high-volume production.
• Wide-temperature environments — Suitable for applications that require reliable operation across -55°C to +105°C.

Unique Advantages

• Large capacitance in an SMD form factor: 330 µF at 35 V delivers bulk capacitance while staying compatible with surface-mount assembly.
• Bi-polar design for flexible circuit use: Eliminates polarity constraints, enabling application where polarity may reverse or AC-coupled circuits are used.
• Production-friendly packaging: Carrier-tape compatibility supports automated pick-and-place processes to reduce assembly handling and cycle time.
• Wide operating temperature and proven endurance: Rated -55°C to +105°C with 2000 hours endurance at 105°C, supporting long-term operation in elevated-temperature applications.
• Defined ripple performance: Specified ripple current values (450 mA @ 120 Hz, 675 mA @ 10 kHz) allow engineers to size capacitors against expected AC stress.
• RoHS compliant: Meets environmental requirements under the 2011/65/EU and (EU)2015/863 directives.
