UVK2V331MRD

The UVK2V331MRD is a miniature-sized aluminum electrolytic capacitor from Nichicon's UVK series, offered in a radial lead (through-hole) standard type package. It delivers 330 µF capacitance at a 350 V rating with specifications targeted for general-purpose electronic designs.

Designed for compact, high-voltage through-hole applications, this part combines a small case (φ25 × 50L) and radial lead termination with defined ripple, leakage and endurance characteristics, making it suitable where a rugged, high-voltage electrolytic is required within the UVK family.

Key Features

• Electrical Rating — 330 µF capacitance with tolerance −20% to +20% and a rated voltage of 350 V.
• Package & Mounting — Radial lead, can-style package; lead spacing 12.5 mm ±0.5 mm; physical size φ25 × 50L (L: 5 × D: 2.5 cm) with a maximum seated height of 1.969 inch.
• Ripple Current — Low-frequency ripple current 1.00 A at 120 Hz and high-frequency ripple current 1.15 A at 10 kHz.
• Leakage and Dissipation — Specified leakage current 4720 µA and tangent of loss angle (tanδ) 0.25 measured at 20°C, 120 Hz.
• Temperature & Endurance — Operating temperature range −40°C to +85°C with an endurance rating of 2000 hours at 85°C (performance limits per datasheet).
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing. Current product status: End Of Life.
• Series Context — Part of Nichicon's UVK miniature-sized series, which provides one rank smaller case sizes compared with the UVR series.

Typical Applications

• General-purpose electronic designs — Through-hole circuits requiring a 350 V, 330 µF electrolytic with defined ripple and leakage specifications.
• High-voltage DC circuits — 350 V rating and specified ripple current make this part applicable where elevated DC voltage handling is required.
• Industrial and commercial equipment — Operating range −40°C to +85°C and 2000 h endurance at 85°C suit equipment that needs sustained performance at elevated temperatures.

Unique Advantages

• High-voltage capability: 350 V rated design supports higher-voltage through-hole applications without adding complexity to the circuit.
• Compact, miniature case: φ25 × 50L dimensions and UVK series sizing help reduce board footprint compared with larger case options.
• Defined ripple handling: Specified low- and high-frequency ripple currents (1.00 A @120 Hz, 1.15 A @10 kHz) allow designers to match capacitor selection to expected operating ripple conditions.
• Documented endurance: Endurance specification of 2000 hours at 85°C with defined limits for capacitance change, tanδ and leakage provides clear reliability expectations.
• RoHS compliant: Material compliance for use in assemblies requiring RoHS conformance.
• Series continuity: Part of the Nichicon UVK family, offering consistent physical and electrical characteristics across the series for design reuse.
