UVR2W470MRD6

The UVR2W470MRD6 is a radial‑lead aluminum electrolytic capacitor offering 47 µF capacitance at a 450 V rated voltage. It is part of Nichicon's UVR miniature series, a standard series for entertainment electronics and other general‑purpose high‑voltage applications.

Compact and through‑hole friendly, this capacitor provides defined ripple handling and endurance characteristics for power filtering and smoothing in high‑voltage circuits. It is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Tolerance: 47 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and decoupling.
• High Rated Voltage: 450 V rated voltage suitable for high‑voltage power rails and smoothing applications.
• Ripple Handling: Low‑frequency ripple current 290 mA (120 Hz) and high‑frequency ripple current 464 mA (10 kHz) to address both mains‑frequency and switching noise.
• Leakage & Loss: Specified leakage current of 946 µA and a tangent of loss angle (tan δ) of 0.25 measured at 20°C, 120 Hz for predictable leakage and dissipation behavior.
• Endurance & Temperature Range: Rated for 2000 hours at 85°C; operating temperature range −25°C to +85°C for reliable service in the specified ambient range.
• Package & Mechanical: Radial lead, can package with size φ22 × 30 mm and 10 mm lead spacing (±0.5 mm), suitable for through‑hole mounting and manual or wave solder assembly.
• Compliance & Packing: RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Entertainment Electronics: Power supply smoothing and decoupling in consumer audio/video and home entertainment equipment where the UVR series is specified.
• High‑Voltage Power Filtering: Bulk and smoothing capacitor for through‑hole high‑voltage rails, leveraging the 450 V rating and defined ripple currents.
• General‑Purpose Electronics: Through‑hole replacement and repair applications that require a compact, radial high‑voltage electrolytic capacitor.

Unique Advantages

• High‑Voltage Capability: 450 V rating enables use on higher DC rails without series stacking or additional components.
• Compact Miniature Size: φ22 × 30 mm can in many cases reduce board footprint compared with larger cans while maintaining required capacitance.
• Defined Ripple Performance: Separate low‑ and high‑frequency ripple current specifications help designers assess performance across switching and mains frequencies.
• Long Endurance at Elevated Temperature: 2000 hours at 85°C provides a quantifiable lifetime metric for thermal budgeting and reliability planning.
• Through‑Hole Format: Radial leads and standard 10 mm lead spacing simplify prototyping, manual assembly, and field replacement.
• Regulatory Compliance: RoHS compliance supports use in products requiring restricted‑substance conformity.
