UVR1H4R7MDD

The UVR1H4R7MDD is a miniature aluminum electrolytic capacitor in Nichicon’s UVR series, supplied in a radial-lead, can-style package. It provides 4.7 µF capacitance at a 50 V rating with a compact footprint suitable for space-constrained, general-purpose electronic designs.

Designed as a standard series for entertainment electronics and general-purpose applications, the part offers defined ripple-current ratings, low leakage, and a rated operating range from –40 °C to 85 °C with 2000 hours endurance at 85 °C.

Key Features

• Capacitance & Voltage — 4.7 µF nominal capacitance, rated to 50 V with a tolerance of −20% to +20%.
• Package & Mounting — Radial lead can; compact size φ5 × 11 mm (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing (±0.5 mm) for tight PCB layouts.
• Temperature & Endurance — Operating temperature range −40 °C to 85 °C and endurance specified as 2000 hours at 85 °C under rated voltage.
• Leakage & Dissipation — Low leakage current specified at 7.05 µA and a dissipation factor (tan δ) of 0.12 measured at 20 °C, 120 Hz.
• Ripple Current Ratings — Low-frequency ripple current: 40 mA at 120 Hz; high-frequency ripple current: 80 mA at 10 kHz, enabling designers to assess performance across frequency ranges.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Entertainment Electronics — Suited for standard circuits in audio, video and related consumer entertainment devices where the UVR series is specified.
• General-Purpose Circuitry — Appropriate for general-purpose power and signal applications that require a compact radial electrolytic capacitor with defined leakage and ripple specs.
• Space-Constrained PCB Designs — The φ5 × 11 mm can and 2 mm lead spacing make it a practical choice for densely populated boards.

Unique Advantages

• Compact radial form factor: φ5 × 11 mm can and short lead spacing reduce board area and simplify placement in compact assemblies.
• 50 V rating for elevated-voltage circuits: Provides headroom for designs that require up to 50 V operation while maintaining a small footprint.
• Endurance at elevated temperature: Rated for 2000 hours at 85 °C, enabling predictable performance in higher-temperature operating environments.
• Low leakage and specified dissipation: Leakage current of 7.05 µA and tan δ of 0.12 (20 °C, 120 Hz) give designers measurable parameters for power-loss and standby calculations.
• Dual-frequency ripple characterization: Separate ripple-current specifications at 120 Hz and 10 kHz (40 mA and 80 mA respectively) help in selecting the part for both low- and high-frequency ripple conditions.
• RoHS compliant: Meets environmental requirements for lead-free designs.
