Designed for general-purpose power applications, this part combines wide operating temperature range, high ripple capability and enhanced safety features to support robust performance in demanding environments.

Key Features

• Rated Performance — 82 µF capacitance with a rated voltage of 400 V; capacitance tolerance specified as -20% to +20%.
• Wide Temperature Range — Operates from -40 °C to +105 °C, suitable for applications requiring extended ambient tolerance.
• High Ripple Capability — Low-frequency ripple current 430 mA (120 Hz) and high-frequency ripple current 688 mA (10 kHz) as specified for this part.
• Endurance — Rated for 2000 hours at 105 °C under D.C. bias plus rated ripple current, with specified limits for capacitance change, tan δ and leakage current after test.
• Leakage Current — Product leakage current listed as 1412 µA; the UAS series datasheet defines leakage current limit as 0.04CV + 100 µA or less after 1 minute at 20 °C.
• Loss Angle (tan δ) — Specified maximum tan δ of 0.15 (measured at 20 °C, 120 Hz) to characterize dissipation factor.
• Safety Design — UAS series includes an improved safety feature for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions to avoid dangerous outcomes.
• Mechanical and Packaging — Radial lead mounting with 7.5 mm lead spacing (±0.5 mm tolerance), case size φ18 × 30.5 mm, available in bulk (no terminal forming) or bag packing; product is in mass production.
• RoHS Compliance — The part is RoHS compliant as stated in product information.

Typical Applications

• General-purpose power circuits — Bulk capacitance and energy storage in 400 V systems where a compact, high-voltage electrolytic capacitor is required.
• Power supply smoothing — Filtering and ripple attenuation in DC rails that benefit from the part’s specified ripple current ratings and 400 V voltage rating.
• Industrial electronics — Designs that require operation across -40 °C to +105 °C and long endurance (2000 hours at 105 °C) for reliable performance in industrial environments.

Unique Advantages

• High-voltage capability: 400 V rated voltage enables use in higher-voltage DC circuits without the need for series capacitor arrangements.
• Compact footprint: φ18 × 30.5 mm can size and radial lead package conserve board space while providing substantial capacitance.
• Enhanced safety features: UAS series’ permissive abnormal-voltage design and pressure relief vent reduce risk in over-voltage events.
• Specified ripple performance: Defined low- and high-frequency ripple currents (430 mA at 120 Hz and 688 mA at 10 kHz) help designers size for thermal and ripple requirements.
• Durability at elevated temperature: 2000-hour endurance at 105 °C supports long-term reliability in hot operating environments.
• Regulatory compliance: RoHS compliance supports use in designs requiring environmental directive conformance.
