UUN2A330MNJ1MS

The UUN2A330MNJ1MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor from Nichicon’s UUN series, providing 33 µF capacitance at a 100 V rating in a surface‑mount package. It is designed for high‑density PC boards and is compatible with automatic mounting using carrier tape.

Built for general‑purpose electronic designs, this part delivers wide operating temperature capability and documented endurance for applications that require reliable bi‑polarized SMD capacitance over a broad temperature range.

Key Features

• Fixed Capacitance & Voltage: 33 µF rated at 100 V for applications needing moderate capacitance at high working voltage.
• Bi‑Polarized Construction: Designed for bi‑polar operation, supporting AC or polarity‑inverting use as described in the UUN series endurance test conditions.
• Wide Operating Temperature: Specified for −55 °C to +105 °C to cover a broad range of environmental conditions.
• Endurance at Elevated Temperature: Lifetime specified as 2000 hours at 105 °C with polarity inversion every 250 hours per the series endurance specification.
• Surface‑Mount Chip Package: Radial, can‑style SMD chip designed for placement on high‑density boards; case dimensions listed as L: 1.6 × D: 1.25 cm with surface mount land size L: 1.28 × W: 1.28 cm.
• Ripple Current Capability: Rated ripple current of 150 mA at 120 Hz and 300 mA at 10 kHz (values provided for this part).
• Leakage Current Specification: Leakage current after 1 minute at rated voltage is specified as not more than 0.03 C·V (µA) per the series datasheet.
• Capacitance Tolerance: ±20% tolerance at 120 Hz, 20 °C.
• RoHS Compliant: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Filtering: Bulk and decoupling use in general electronic systems where a bi‑polarized SMD capacitor is required.
• AC/Polarity‑Reversing Circuits: Circuits that experience polarity inversion or AC coupling can use the bi‑polarized construction and endurance cycle characteristics.
• High‑Density PCB Designs: Surface‑mount chip package optimized for automatic mounting and compact board layouts.
• Temperature‑Variable Environments: Designs that require operation across −55 °C to +105 °C benefit from the capacitor’s specified temperature range and endurance rating.

Unique Advantages

• Bi‑polarized flexibility: Enables AC and polarity‑inverting use without the constraints of polarized electrolytics, simplifying design where signal polarity can change.
• SMD chip format for dense boards: Radial can SMD package and carrier‑tape compatibility streamline automated assembly and reduce layout area compared with larger leaded parts.
• Documented endurance: 2000 hours at 105 °C with defined polarity inversion intervals provides an evidence‑based reliability metric for thermal stress planning.
• Wide operating range: −55 °C to +105 °C supports deployment across diverse environmental conditions without additional qualification claims.
• Measured ripple performance: Specified ripple current values at 120 Hz and 10 kHz help designers balance thermal and lifetime considerations in power applications.
• Regulatory compliance: RoHS compliance supports use in designs requiring restricted‑substance conformance.
