UVR1V4R7MDD

The UVR1V4R7MDD is a miniature aluminum electrolytic capacitor from Nichicon’s UVR series. It is a standard-type radial-lead electrolytic capacitor specified at 4.7 µF and 35 V, intended for general-purpose and entertainment electronics applications.

With a compact φ5 × 11 mm can, radial mounting and a rated operating range of −40°C to 85°C, the UVR1V4R7MDD offers predictable performance metrics including defined ripple current, low leakage and a 2000-hour endurance at 85°C.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal capacitance with tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage & Polarization — 35 V rated voltage; polarized aluminum electrolytic construction for DC smoothing and decoupling.
• Loss Angle (tan δ) — tanδ specified at 0.14 (measured at 20°C, 120 Hz), providing a quantitative dielectric loss parameter for circuit analysis.
• Ripple Current Performance — Low-frequency ripple current 40 mA at 120 Hz and high-frequency ripple current 80 mA at 10 kHz for mixed-frequency filtering tasks.
• Leakage Current — Measured leakage current 4.935 µA, useful for low-leakage bias requirements.
• Reliability & Lifetime — Endurance rated 2000 hours at 85°C with defined post-life limits for capacitance, tanδ and leakage current.
• Mechanical & Mounting — Radial lead package (φ5 × 11 mm); lead spacing 2 mm with ±0.5 mm tolerance; bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Entertainment Electronics — Suited for standard series use in consumer entertainment devices where miniature electrolytic decoupling is required.
• General-Purpose Circuits — Useful for DC smoothing and decoupling in a wide range of general-purpose electronic assemblies.
• Space-Constrained PCB Designs — Compact φ5 × 11 mm can and 2 mm lead spacing make it suitable for tight layouts and dense board assemblies.

Unique Advantages

• Compact footprint: Small φ5 × 11 mm can and short seated height (L: 1.1 × D: 0.5 cm) reduce PCB real estate for space-limited designs.
• Quantified AC performance: Specified ripple currents at 120 Hz and 10 kHz allow designers to assess suitability for both low- and high-frequency filtering.
• Low measured leakage: A leakage current of 4.935 µA supports applications where low bias leakage is important.
• Defined endurance: 2000 hours at 85°C with measurable post-life limits helps predict in-service behavior and maintenance intervals.
• Radial lead convenience: Standard radial-lead construction and options for bulk or bag packing simplify assembly and handling for through-hole manufacturing.
• Regulatory compliance: RoHS status provides environmental conformity for product assemblies requiring restricted substance compliance.
