UUN0J332MNQ1MS

The UUN0J332MNQ1MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor designed for surface mounting on high‑density printed circuit boards. It delivers a high capacitance value in a compact SMD can package and is intended for general purpose electronic equipment where bipolar operation, temperature endurance, and automated assembly compatibility are required.

Key value propositions include bi‑polar operation across a wide temperature range (‑55°C to +105°C), a long rated lifetime (2000 hours at 105°C), and compatibility with carrier‑tape automatic mounting processes — enabling reliable bulk energy storage or signal coupling in dense assemblies.

Key Features

• Capacitance & Voltage — 3.3 mF rated capacitance at 6.3 V with tolerance of −20% to +20% for design margin planning.
• Bi‑Polar Construction — Bi‑polarized capacitor suited for applications where polarity may invert or AC coupling is required.
• Wide Temperature Range — Qualified for operation from −55°C to +105°C to support demanding thermal environments.
• Endurance — Rated lifetime of 2000 hours at 105°C; datasheet endurance test includes polarity inversion every 250 hours to validate long‑term stability.
• Ripple Current Handling — Measured ripple current of 920 mA at 120 Hz and 1.058 A at 10 kHz to support filtering and decoupling in power and signal paths.
• Chip‑Type SMD Package — Radial, can‑style SMD package sized L: 2.15 × D: 1.8 cm with recommended PCB land size L: 1.83 × W: 1.83 cm for high‑density board layouts.
• Low Leakage Characteristic — Series specification: leakage current not more than 0.03CV (μA) after 1 minute’s application of rated voltage at 20°C (per datasheet series data).
• Assembly Ready — Designed for automatic mounting machines fed with carrier tape for efficient high‑volume production.
• Environmental Compliance — RoHS‑compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Electronic Equipment — Bulk energy storage and decoupling in compact SMD assemblies where higher capacitance is required in a chip package.
• High‑Density PCB Assemblies — Surface‑mount chip design and recommended land pattern support dense board layouts and automated placement.
• Bipolar/AC Coupling Circuits — Bi‑polarized construction supports circuits with reversing polarity or AC signal coupling needs.
• Automated Manufacturing — Compatible with carrier‑tape feed for pick‑and‑place lines, helping streamline production and assembly.

Unique Advantages

• High Capacitance in an SMD Can — 3.3 mF capacitance in a chip‑type package reduces board area compared with discrete through‑hole solutions while maintaining required energy storage.
• Robust Thermal Endurance — Rated for 2000 hours at 105°C, enabling reliable operation in thermally challenging environments.
• Designed for Bipolar Operation — Bi‑polarized construction eliminates the need to worry about polarity in AC or reversing‑voltage applications.
• Production‑Friendly — Carrier‑tape compatibility and SMD form factor simplify automated assembly and reduce handling time during manufacturing.
• Measured Ripple Capability — Specified ripple current ratings at 120 Hz and 10 kHz provide designers with quantifiable data for power‑filter and decoupling calculations.
• Regulatory Compliance — RoHS compliance supports environmentally regulated product builds.
