UVK1H472MRD

The UVK1H472MRD is a Nichicon UVK series miniature aluminum electrolytic capacitor in a radial-lead can. It delivers 4700 µF of polarized capacitance at a 50 V rating in a compact φ20 × 40 mm package with 10 mm lead spacing, targeted for general-purpose power applications.

Engineered for sustained operation up to 85°C, this part combines high bulk capacitance, measurable ripple-current capability, and a 2000-hour endurance rating for designers needing reliable DC smoothing and bulk energy storage on 50 V rails.

Key Features

• Capacitance and Tolerance — 4700 µF (4.7 mF) nominal with a tolerance of -20% to +20% measured at 120 Hz, 20°C.
• Rated Voltage — 50 V working voltage suitable for higher-voltage DC rail applications.
• Ripple Current Performance — Rated low-frequency ripple current of 2.9 A at 120 Hz and high-frequency ripple current of 3.335 A at 10 kHz, enabling effective handling of AC ripple on DC rails.
• Thermal and Endurance — Operating temperature range from -40°C to +85°C with an endurance specification of 2000 hours at 85°C with rated voltage applied.
• Loss and Leakage — Dissipation factor (tan δ) of 0.18 (measured at 20°C, 120 Hz) and specified leakage current of 7050 µA in the product data.
• Package and Mounting — Radial lead, polarized can in a miniature UVK series footprint (φ20 × 40 mm) with 10 mm lead spacing; available in bulk or bag packing.
• Compliance — RoHS compliant per product information.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on DC power rails up to 50 V where high capacitance is required.
• Bulk energy storage — Hold-up capacitance for systems that require larger stored charge in a compact through-hole package.
• Power supply rail stabilization — Damp voltage ripple and support transient load changes on 50 V rails in industrial and electronic equipment.

Unique Advantages

• High bulk capacitance in a compact footprint: 4700 µF provided in a φ20 × 40 mm radial can helps reduce board area compared with larger packages.
• Designed for elevated-temperature operation: 2000 hours endurance at 85°C with rated voltage applied supports sustained reliability under heat stress.
• Strong ripple-current capability: 2.9 A at 120 Hz and 3.335 A at 10 kHz allow effective handling of both low- and high-frequency ripple components.
• Radial-lead ease of use: Through-hole radial leads and 10 mm lead spacing simplify mechanical mounting and prototyping for general-purpose boards.
• Series miniaturization: UVK series offers one rank smaller case sizes than UVR, enabling smaller BOM footprint for comparable capacitance.
• RoHS compliance: Meets RoHS directive requirements as specified in the product data.
