UVR1E4R7MDD

The UVR1E4R7MDD from Nichicon is a miniature aluminum electrolytic capacitor in the UVR standard series. It is a radial-lead, polarized component offering 4.7 µF capacitance at a 25 V rating and is specified for general-purpose and entertainment electronics applications.

Designed for compact through-hole assemblies, this capacitor combines a small φ5 × 11 mm can with practical performance parameters—including defined ripple current, low leakage, and a 2000-hour endurance at 85°C—to support low-voltage power filtering and decoupling needs.

Key Features

• Capacitance and Voltage — 4.7 µF nominal capacitance with a 25 V rated voltage, suitable for low-voltage power rails and decoupling functions.
• Compact Radial Package — Miniature φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm), designed for radial lead mounting in space-constrained boards.
• Loss Tangent (tan δ) — tanδ = 0.16 measured at 20°C, 120 Hz, providing predictable dissipation characteristics for design margin calculations.
• Ripple Current Ratings — Low-frequency ripple: 35 mA at 120 Hz; high-frequency ripple: 70 mA at 10 kHz, enabling effective filtering across common frequencies.
• Low Leakage — Specified leakage current of 4 µA, minimizing standby current in low-power circuits.
• Endurance — Life rating of 2000 hours at 85°C with specified limits for capacitance change, tanδ, and leakage current after test.
• Wide Operating Temperature — Rated for –40°C to +85°C to cover standard ambient and equipment operating environments.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit assembly and procurement preferences.

Typical Applications

• Entertainment Electronics — Standard-series component suitable for power filtering and decoupling in consumer entertainment devices.
• General-Purpose Circuits — Used for smoothing and bypassing on low-voltage rails up to 25 V where a compact through-hole capacitor is required.
• Embedded and Control Boards — Radial-lead form factor simplifies replacement and serviceability while providing defined ripple and leakage characteristics.

Unique Advantages

• Space-Efficient Design: Small φ5 × 11 mm can and tight 2.0 mm lead spacing enable placement in compact assemblies without sacrificing rated capacitance.
• Measured Performance: Specified tanδ, ripple current values, and low leakage allow predictable behavior in power-filtering and decoupling roles.
• Durability Under Load: 2000-hour endurance at 85°C gives designers a quantifiable life expectation for thermal stress conditions.
• Through-Hole Simplicity: Radial lead mounting supports straightforward assembly and prototyping workflows.
• Regulatory Compliance: RoHS conformity supports deployment in environments where substance compliance is required.
• Flexible Packaging: Bulk and bag packing options accommodate different production and stocking needs.
