UVK2W3R3MPD

The UVK2W3R3MPD is a Nichicon UVK series miniature aluminum electrolytic capacitor in a radial‑lead can. It provides 3.3 µF capacitance at a 450 V rating in a compact φ10 × 12.5 mm package with 5 mm lead spacing, designed for general‑purpose electronic applications that require a small, high‑voltage polarized capacitor.

With a rated lifetime of 2000 hours at 85°C and RoHS compliance, this part balances compact size, high voltage capability, and predictable endurance for use in space‑constrained power circuitry and other general‑purpose designs.

Key Features

• Electrical Performance — 3.3 µF nominal capacitance with tolerance −20% to +20%, rated at 450 V. Specified tanδ (DF) of 0.25 at 20°C, 120 Hz for the 350–450 V range.
• Ripple Current Handling — Low‑frequency ripple current of 40 mA at 120 Hz and high‑frequency ripple current of 64 mA at 10 kHz, supporting filtering and decoupling in high‑voltage circuits within the stated limits.
• Compact Radial Package — Miniature radial can measuring φ10 × 12.5 mm with 5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing without terminal forming for straightforward through‑hole assembly.
• Reliability & Endurance — Rated for 2000 hours at 85°C under rated voltage with specified limits for capacitance change, tanδ, and leakage current after endurance testing.
• Leakage Current — Specified leakage current example 159.4 µA (measured condition provided in product data), consistent with the UVK series leakage performance guidelines.
• Environmental Compliance — RoHS compliant per product data.

Typical Applications

• General‑Purpose Electronics — Use as a polarized energy storage, decoupling or filtering capacitor in a wide range of electronic designs described as “general purpose.”
• High‑Voltage Power Circuits — Suited for circuits requiring a compact capacitor rated to 450 V where space is limited and a radial lead package is preferred.
• Compact Power Modules — Fits small through‑hole assemblies that need a high‑voltage electrolytic solution with predictable endurance at elevated temperature.

Unique Advantages

• High Voltage in a Small Footprint: 450 V rating combined with a φ10 × 12.5 mm can size provides high working voltage where board space is constrained.
• Established Endurance: 2000 hours at 85°C under rated voltage gives designers a clear specification for expected life under high‑temperature operating conditions.
• Radial Lead Simplicity: 5 mm lead spacing and standard radial can form factor simplify through‑hole assembly and mechanical placement.
• Measurable Loss Characteristics: Specified tanδ (0.25 at 20°C, 120 Hz for the 350–450 V range) aids in AC loss budgeting and thermal planning.
• RoHS Compliant: Meets RoHS directive requirements as noted in the product data for regulated material compliance.

Why Choose UVK2W3R3MPD?

UVK2W3R3MPD positions itself as a compact, high‑voltage aluminum electrolytic capacitor for designs that need a polarized capacitor with a clear endurance rating and measurable AC characteristics. Its miniature radial can, 450 V rating, and 2000 h life at 85°C make it appropriate for general‑purpose high‑voltage circuits where board space and predictable reliability matter.

This part is suitable for engineers and procurement teams specifying components for space‑constrained through‑hole assemblies that require RoHS compliance, defined leakage behavior, and documented ripple current capability across low and high frequency conditions.
