UUG2A331MNJ1MS

The UUG2A331MNJ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UUG series, offering 330 µF capacitance at a 100 V rating in a compact radial can SMD package (φ18 × 21.5 mm). It targets designs requiring high capacitance density in a board-mounted chip-style package with a wide operating temperature range of −40 °C to 85 °C.

Designed for demanding environments, the part delivers defined ripple-current performance across low and high frequencies, an endurance rating of 2000 hours at 85 °C, and is qualified to AEC‑Q200 for automotive applications.

Key Features

• Capacitance & Voltage: 330 µF rated capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Package & Mounting: Radial can, chip-type SMD package sized φ18 × 21.5 mm (L: 21.5 mm, D: 18 mm) for surface-mount assembly; surface-mount land size specified as 1.83 × 1.83 cm.
• Thermal Range & Endurance: Operating temperature −40 °C to 85 °C with endurance specified as 2000 hours at 85 °C under rated voltage.
• Ripple Current Performance: Low-frequency ripple current 825 mA at 120 Hz and high-frequency ripple current 1.238 A at 10 kHz—specified frequency coefficients available in the datasheet for other frequency points.
• Loss & Leakage: Tangent of loss angle (tan δ) 0.08 (measurement condition 20 °C, 120 Hz at 100 V) and leakage current 990 µA measured per the product specification.
• Automotive Qualification: AEC‑Q200 rating included, supporting use in automotive applications subject to that standard.

Typical Applications

• Automotive power systems: Board-mounted decoupling and bulk energy storage in automotive electronic modules where 100 V operation and AEC‑Q200 qualification are required.
• High-voltage power supplies: Bulk capacitance in compact surface-mount power-supply designs that require 100 V rated components and defined ripple-current handling.
• Industrial control electronics: Energy smoothing and filtering in control modules operating across −40 °C to 85 °C with long endurance requirements.

Unique Advantages

• High-voltage capability: 100 V rating allows use in higher-voltage boards without moving to larger discrete parts, preserving PCB real estate.
• Compact SMD can package: Chip-type radial can (φ18 × 21.5 mm) provides higher capacitance in a surface-mount form factor for dense assemblies.
• Defined ripple performance: Specified low- and high-frequency ripple currents (825 mA @120 Hz, 1.238 A @10 kHz) help designers size components for both mains-frequency and switching-frequency environments.
• Endurance specified at elevated temperature: 2000 hours at 85 °C under rated voltage gives a clear reliability target for life-limited designs.
• Automotive-ready qualification: Inclusion of AEC‑Q200 supports selection for automotive electronic modules requiring that qualification.
