UVK1H331MPD

The UVK1H331MPD is a miniature aluminum electrolytic capacitor in Nichicon’s UVK series, configured as a radial-lead, standard-type device. It delivers 330 µF capacitance at 50 V in a compact φ10 × 16 mm can and is intended for general-purpose electronic designs.

Designed for board-level use, the UVK1H331MPD combines a wide operating temperature range (−40 °C to 85 °C), specified ripple current ratings at both low and high frequencies, and a 2000-hour endurance rating at 85 °C to meet common power-smoothing and energy-storage needs in compact assemblies.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 50 V rated voltage and a tolerance of −20% to +20%.
• Miniature Radial Package — Compact φ10 × 16 mm can in a radial-lead configuration with 5 mm lead spacing (±0.5 mm).
• Temperature & Endurance — Operating temperature range of −40 °C to 85 °C and a life rating of 2000 hours at 85 °C under rated voltage.
• Ripple Current Performance — Specified low-frequency ripple current of 590 mA at 120 Hz and high-frequency ripple current of 885 mA at 10 kHz.
• Loss and Leakage Characteristics — Tangent of loss angle (tanδ) of 0.12 (measured at 20 °C, 120 Hz) and a specified leakage current of 495 µA.
• Polarized, Standard Type — Polarized aluminum electrolytic construction for general-purpose filtering and energy-storage applications.
• Compliance & Packaging — RoHS-compliant; available in bulk (no terminal forming) and bag packing. Product is in mass production.

Typical Applications

• General-purpose electronics — Suited to designs that require 330 µF at 50 V in a compact radial-lead package for board-level power circuitry.
• Power smoothing and decoupling — Applicable where a polarized electrolytic capacitor with specified ripple-current handling and temperature endurance is needed.
• Compact assemblies — Fits space-constrained layouts thanks to its miniature φ10 × 16 mm can and radial-lead form factor.

Unique Advantages

• Compact footprint: φ10 × 16 mm miniature can delivers 330 µF in a smaller case size consistent with the UVK series’ reduced dimensions.
• Dual-frequency ripple capability: Rated ripple currents of 590 mA (120 Hz) and 885 mA (10 kHz) help address both low- and high-frequency ripple demands.
• Robust temperature endurance: 2000-hour life at 85 °C provides a measurable endurance metric for designs exposed to elevated operating temperatures.
• Predictable electrical characteristics: Specified tanδ (0.12 at 20 °C, 120 Hz) and a defined leakage current (495 µA) allow designers to model performance accurately.
• Radial-lead convenience: 5 mm lead spacing (±0.5 mm) and standard radial can simplify through-hole assembly and prototyping.
• Regulatory compliance: RoHS-compliant construction aligns with common environmental requirements for electronic components.
