UVK1C331MED

The UVK1C331MED is a radial-lead aluminum electrolytic capacitor in the Nichicon UVK miniature series, providing 330 µF capacitance at a 16 V rating. Designed for general-purpose circuitry, this compact polarized capacitor delivers measurable ripple handling and defined endurance for compact electronic power and support circuitry.

Its miniature case (φ6.3 × 11 mm) and radial-lead mounting make it suitable where board space is limited and conventional axial or larger can sizes are impractical. The UVK series is compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Key Features

• Electrical Performance — 330 µF nominal capacitance with tolerance −20% to +20% and rated voltage of 16 V; tangent of loss angle (tanδ) 0.20 measured at 20 °C, 120 Hz.
• Ripple Current Capability — Low-frequency ripple current 320 mA at 120 Hz and high-frequency ripple current 480 mA at 10 kHz, supporting AC ripple in power rails.
• Leakage Current — Specified leakage current of 158.4 µA after rated voltage application at 20 °C, supporting predictable standby behavior in designs.
• Temperature and Endurance — Operating temperature range −40 °C to +85 °C with endurance rating of 2000 hours at 85 °C under rated voltage.
• Compact Radial Package — φ6.3 × 11 mm can (size L: 1.1 × D: 0.63 cm) with 2.5 mm lead spacing (±0.5 mm); radial-lead mounting simplifies through-hole assembly and mechanical retention.
• Packaging Options — Available in Bulk (no terminal forming) and Bag packing to support different assembly and handling workflows.

Typical Applications

• Compact power supplies — Local bulk capacitance and ripple smoothing in small DC–DC converters and board-mounted supply modules where space is constrained.
• Embedded and consumer electronics — General-purpose energy storage and filtering on PCB power rails for compact devices requiring polarized electrolytic capacitance.
• Industrial control modules — Use in control and interface boards that need defined endurance at elevated temperatures (2000 h at 85 °C) and stable performance across −40 °C to +85 °C.

Unique Advantages

• Miniature footprint: φ6.3 × 11 mm can reduces board area compared with larger electrolytic parts while maintaining 330 µF capacitance.
• Clear performance specifications: Tangent of loss angle (tanδ), leakage current, and ripple current are specified under defined measurement conditions (20 °C, 120 Hz and 10 kHz), aiding predictable design margins.
• Through-hole robustness: Radial-lead construction provides mechanical stability on PCBs and straightforward wave/hand soldering compatibility for conventional assembly processes.
• Endurance-rated for elevated temperature: 2000 hours at 85 °C under rated voltage gives a defined reliability target for thermal-stressed designs.
• Series-level RoHS compliance: UVK series compliance with RoHS directives supports regulatory alignment for many global product programs.
