UVK1A331MED

The UVK1A331MED is a miniature aluminum electrolytic capacitor from Nichicon’s UVK series, provided in a radial‑lead, standard-type can. It delivers 330 µF capacitance at a 10 V rating in a compact φ6.3×11 mm package suited for general-purpose electronic designs.

Designed for space‑constrained, through‑hole assemblies, the part offers defined ripple performance, low leakage, and a 2000‑hour endurance rating at 85°C, making it appropriate for a range of general‑purpose applications requiring reliable low‑voltage bulk capacitance.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 10 V, providing bulk storage in a miniature package.
• Polarized, Radial‑Lead Package — Standard radial lead can with 2.5 mm lead spacing (±0.5 mm) for through‑hole assembly and mechanical stability.
• Compact Dimensions — Package size φ6.3 × 11 mm (L × D) for tight PCB layouts and small form‑factor designs.
• Loss Angle (tan δ) — tan δ = 0.24 (measured at 20°C, 120 Hz), giving a defined dissipation characteristic for circuit design considerations.
• Ripple Current Ratings — Low‑frequency ripple current 290 mA at 120 Hz and high‑frequency ripple current 435 mA at 10 kHz, specified for evaluating AC stress performance.
• Leakage Current — Specified leakage current of 99 µA for predictable standby and bias behavior after voltage application.
• Endurance — Rated life of 2000 hours at 85°C with defined limits for capacitance change, dissipation factor, and leakage current after endurance testing.
• Operating Temperature — Specified operating range from −40°C to +85°C to cover typical ambient conditions for general‑purpose electronics.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support various assembly workflows.
• RoHS Compliance (series) — UVK series is noted as compliant to the RoHS directive (2011/65/EU, (EU)2015/863) in the series documentation.

Typical Applications

• General‑purpose electronic circuits — Provides 330 µF bulk capacitance in a compact radial‑lead form for a wide range of board‑level designs categorized as general purpose.
• Through‑hole assemblies — Radial lead spacing of 2.5 mm and compact can size suit conventional through‑hole mounting and manual or wave solder processes.
• Space‑constrained low‑voltage modules — Miniature φ6.3×11 mm footprint delivers significant capacitance at 10 V where PCB real estate is limited and moderate ripple handling is required.

Unique Advantages

• High capacitance in a miniature footprint: 330 µF in a φ6.3×11 mm can reduces board area needed for bulk energy storage.
• Defined ripple performance: Specified ripple currents at 120 Hz and 10 kHz allow designers to assess AC stress and thermal loading accurately.
• Predictable leakage and dissipation: Leakage current of 99 µA and tan δ = 0.24 (20°C, 120 Hz) support reliable biasing and loss calculations.
• Endurance specification: 2000 hours at 85°C with clear post‑test limits helps plan for lifetime and reliability targets.
• Through‑hole readiness: Radial lead format and standard lead spacing simplify integration into legacy and mixed‑technology assemblies.
• RoHS‑aligned series: UVK series compliance to RoHS directives is indicated in the series documentation for regulatory planning.
