UUN1C331MNQ1MS

The UUN1C331MNQ1MS from Nichicon is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. It delivers 330 µF capacitance at a 16 V rating in an SMD-compatible radial can package.

Engineered for general-purpose electronic circuits, this part offers a wide operating temperature range of -55 °C to +105 °C and is compatible with automatic mounting equipment fed by carrier tape. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 16 V for higher energy storage in compact SMD form factors.
• Bi-Polarized Construction — Designed as a bi-polarized series to support applications that require non-polar or polarity-insensitive operation across the specified temperature range.
• Surface-Mount Package — Chip-type radial can SMD package suitable for placement on high-density printed circuit boards; compatible with automatic carrier-tape mounting.
• Wide Temperature Range — Specified for operation from -55 °C to +105 °C to handle demanding thermal environments.
• Endurance — Rated for 2000 hours at 105 °C (endurance condition per datasheet), with capacitance and leakage current limits defined after test recovery.
• Ripple Current Ratings — Low-frequency ripple current of 310 mA at 120 Hz and high-frequency ripple current of 465 mA at 10 kHz to support power-conditioning roles.
• Tolerance & Loss — Capacitance tolerance ±20%; specified tan δ characteristics and leakage current limits are provided in the datasheet for design verification.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose PCB assemblies — Surface-mount, chip-type design intended for use on high-density printed circuit boards where compact, higher capacitance SMD capacitors are required.
• Automated production lines — Compatible with carrier-tape feeding for automatic mounting machines, simplifying assembly for volume manufacturing.
• Temperature-challenged environments — Suitable for electronic circuits that require stable capacitance across a wide operating range of -55 °C to +105 °C.

Unique Advantages

• Higher capacitance in SMD form — 330 µF in a chip-type radial can delivers significant capacitance for designs constrained by board area.
• Polarity flexibility — Bi-polarized construction removes polarity constraints that can complicate layout and system integration in certain circuits.
• Manufacturing-friendly — Designed for carrier-tape automated mounting to streamline pick-and-place assembly and reduce handling complexity.
• Built for thermal endurance — Endurance tested at 105 °C for 2000 hours, providing predictable behavior in elevated-temperature applications.
• Measured ripple performance — Provided ripple current specifications at 120 Hz and 10 kHz let engineers size components against expected power-conditioning loads.
• Regulatory compliance — RoHS compliance supports use in markets requiring restricted-substance conformity.
