UVK2V4R7MPD

The UVK2V4R7MPD is a Nichicon UVK series radial-lead aluminum electrolytic capacitor offering 4.7 µF capacitance at a 350 V rated voltage. It is a polarized, miniature-sized capacitor designed for general-purpose electronic circuits that require a compact, high-voltage electrolytic solution.

With a small φ8 × 11.5 mm can, lead spacing of 3.5 mm and a specified endurance of 2000 hours at 85°C, this part targets applications that need reliable long-term performance within the specified temperature range.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal capacitance with tolerance -20% to +20% (specified at 120 Hz, 20°C).
• High Voltage Rating — Rated for 350 V operation, suitable for circuits that require elevated DC voltage handling.
• Low and High Frequency Ripple Capability — Specified ripple currents of 55 mA at 120 Hz and 88 mA at 10 kHz provide defined performance across frequency ranges.
• Electrical Losses — Tangent of loss angle (tan δ) of 0.25 measured at 20°C, 120 Hz for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 165.8 µA for designers to budget standby and bias currents accurately.
• Temperature & Endurance — Operating range from -40°C to +85°C with an endurance rating of 2000 hours at 85°C.
• Compact Radial Package — φ8 × 11.5 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm) for through-hole assemblies and prototyping.
• Regulatory Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing. Status: Mass production.

Typical Applications

• General-purpose power filtering — Use in general-purpose circuits where 4.7 µF at 350 V is required for smoothing and decoupling in DC circuits.
• High-voltage board designs — Suited for through-hole assemblies that need a compact, high-voltage electrolytic capacitor with defined ripple and leakage characteristics.
• Compact radial-lead assemblies — The small φ8 × 11.5 mm can and 3.5 mm lead spacing make it appropriate for space-conscious through-hole layouts.

Unique Advantages

• Compact high-voltage solution: 350 V rating in a miniature φ8 × 11.5 mm radial can enables space-saving designs that still require elevated voltage capability.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 10 kHz allow designers to evaluate behavior across low- and high-frequency stress conditions.
• Defined long-term endurance: 2000 hours at 85°C provides a clear baseline for life expectancy planning in sustained-temperature environments.
• Predictable electrical losses and leakage: Provided tan δ (0.25 at 20°C, 120 Hz) and leakage current figures (165.8 µA) support accurate thermal and power-loss budgeting.
• Through-hole compatibility: Radial-lead form factor with 3.5 mm lead spacing simplifies prototyping and assembly on conventional PCBs.
• RoHS compliant and production-ready: Meets RoHS requirements and is available in mass-production packaging options for volume procurement.
