UVK2W4R7MPD

The UVK2W4R7MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series designed for general-purpose high-voltage applications. It combines a compact can package with a 450 V rating and a 4.7 µF capacitance for use where space is limited but higher voltage capability is required.

Engineered for compact power and filtering roles, this capacitor offers defined ripple current performance and a 2000-hour endurance at 85 °C, making it suitable for industrial and consumer electronic designs that require reliable high-voltage decoupling in a small form factor.

Key Features

• Rated Capacitance: 4.7 µF with tolerance −20% to +20%, specified at 120 Hz and 20 °C for predictable circuit behavior.
• High Voltage Rating: 450 V rated voltage for high-voltage filtering and decoupling in compact assemblies.
• Loss Tangent (tan δ): tanδ = 0.25 (measured at 20 °C, 120 Hz), enabling designers to account for dielectric losses in AC and ripple calculations.
• Ripple Current Performance: Low-frequency ripple current 46 mA at 120 Hz and high-frequency ripple current 73.6 mA at 10 kHz to support smoothing and noise suppression across a range of frequencies.
• Leakage Current: Specified leakage current 184.6 µA for predictable standby and bias behavior after rated voltage application.
• Reliability / Endurance: 2000 hours life at 85 °C with capacitance change within ±20% and leakage current not exceeding initial specified value after endurance testing.
• Compact Radial Package: Can case φ10 × 12.5 mm (diameter × length) with 5 mm lead spacing (±0.5 mm) for through-hole mounting in space-constrained designs.
• Mounting & Packaging: Radial lead configuration, available in bulk (no terminal forming) or bag packing; mass production status for consistent supply.
• Environmental Compliance: RoHS compliant as noted for the UVK series.

Typical Applications

• High-voltage power supplies: Filtering and decoupling in compact high-voltage supply stages where a 450 V rating is required and board space is limited.
• Industrial control electronics: Local energy storage and ripple suppression for control circuits and power rails operating at elevated voltages.
• Consumer electronics with compact HV sections: Smoothing and noise reduction in compact modules that need a small, high-voltage electrolytic solution.

Unique Advantages

• Compact high-voltage capability: Delivers 450 V rating in a φ10 × 12.5 mm can, enabling high-voltage designs with reduced board footprint.
• Frequency-aware ripple handling: Specified ripple current values at both 120 Hz and 10 kHz let designers size components for both low- and high-frequency filtering needs.
• Defined endurance data: 2000-hour life at 85 °C with quantified post-test limits for capacitance, tanδ and leakage current supports reliability planning.
• Predictable loss characteristics: tanδ specified at measurement conditions (20 °C, 120 Hz) helps with thermal and AC loss budgeting in power designs.
• Through-hole form factor: Radial leads and standard 5 mm spacing simplify insertion and wave/manual assembly in mixed-technology PCBs.
• RoHS compliance: Environmentally compliant for designs requiring restricted-substance adherence.
