UUN2A330MNQ1MS

The UUN2A330MNQ1MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor designed for surface mounting on high‑density PC boards. It delivers 33 µF capacitance at a 100 V rating with a wide operating temperature range of −55 to +105°C, targeting general‑purpose electronic designs that require reliable bipolar capacitance and surface‑mount assembly.

Its construction and packaging make it applicable to automated placement from carrier tape, offering defined electrical and mechanical specifications for embedded and board‑level power conditioning and signal applications.

Key Features

• Electrical Rating — 33 µF capacitance with a 100 V rated voltage and ±20% tolerance (at 120 Hz, 20°C), providing a defined bipolar capacitance option for AC or polarity‑varying circuits.
• Bi‑Polarized Design — Bi‑polarized construction enables operation when polarity reverses, suitable for circuits that require non‑polar behavior across the −55 to +105°C temperature range.
• Temperature and Endurance — Specified for operation from −55 to +105°C with endurance of 2000 hours at 105°C (with polarity inversion every 250 hours) while meeting capacitance, tan δ and leakage current limits per the series specifications.
• Ripple Performance — Rated ripple current of 150 mA at 120 Hz and 300 mA at 10 kHz for this part, with frequency coefficients provided in the series datasheet to calculate ripple capability across frequencies.
• Surface‑Mount Chip Packaging — Radial can, SMD chip form factor sized L: 1.6 × D: 1.25 cm with a recommended surface‑mount land size of L: 1.28 × W: 1.28 cm; compatible with automatic mounting from carrier tape.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Conditioning — Used for decoupling and smoothing in board‑level power rails where bipolar capacitance and a 100 V rating are required.
• AC‑Coupled and Signal Circuits — Suitable where polarity can reverse or where bipolar capacitor behavior is needed across temperature extremes.
• High‑Density PCB Designs — Chip form factor and carrier‑tape compatibility enable automated placement on compact, densely populated boards.

Unique Advantages

• Bi‑polarized operation: Removes polarity constraints for designs that experience voltage reversal, simplifying circuit implementation where non‑polar behavior is needed.
• Wide temperature range: Rated from −55 to +105°C, enabling use across a broad set of environmental conditions without derating outside the specified range.
• Defined endurance: 2000 hours at 105°C with specified post‑test limits for capacitance, tan δ and leakage current, supporting predictable life‑cycle planning.
• Frequency‑aware ripple ratings: Published ripple current values at 120 Hz and 10 kHz plus series frequency coefficients allow designers to size capacitors for expected ripple conditions.
• Surface‑mount automation friendly: Carrier‑tape compatibility and chip packaging streamline automated assembly on high‑density PCBs.
• RoHS compliance: Conforms to relevant RoHS directives for environmental and regulatory alignment.
