UVR2E4R7MPD

The UVR2E4R7MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UVR series. It delivers 4.7 µF capacitance at a 250 V rating in a compact φ8 × 11.5 mm package designed for general-purpose and entertainment electronics applications.

Engineered for compact power circuits, the UVR2E4R7MPD combines a small footprint and radial-lead mounting with defined ripple-current performance, controlled loss (tan δ), and a 2000-hour endurance at 85°C for reliable service in temperature-constrained designs.

Key Features

• Capacitance & Voltage — 4.7 µF rated capacitance with a 250 V rating, suitable for circuits requiring moderate energy storage at elevated voltages.
• Package & Mounting — Miniature radial-lead can package, size φ8 × 11.5 mm (D: 0.8 cm × L: 1.15 cm) with 3.5 mm lead spacing (±0.5 mm), for through-hole PCB assemblies.
• Loss Characteristics — tan δ = 0.2 (measurement condition: 20°C, 120 Hz), providing a defined dissipation factor for design calculations.
• Ripple-Current Performance — Specified low-frequency ripple current of 55 mA at 120 Hz and high-frequency ripple current of 88 mA at 10 kHz to support smoothing and decoupling tasks under AC ripple.
• Leakage Current — Leakage current specified at 147 µA, enabling predictable bias and standby current behavior.
• Reliability & Endurance — Rated for 2000 hours at 85°C; capacitors meet endurance criteria after restoration to 20°C following the rated-voltage endurance test.
• Operating Range & Compliance — Operates from −40°C to +85°C and is RoHS compliant.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to support production and prototyping workflows.

Typical Applications

• Entertainment Electronics — Designed as part of the UVR standard series for entertainment electronics, suitable for compact power-supply and signal circuits in consumer AV equipment.
• General-Purpose Electronic Equipment — Use in general-purpose PCB-mounted power circuits that require a 250 V-rated electrolytic capacitor with controlled leakage and ripple characteristics.
• Power Supply Smoothing and Decoupling — Fits applications where defined low- and high-frequency ripple handling and predictable dissipation (tan δ) are required for stability and noise reduction.

Unique Advantages

• Compact footprint: φ8 × 11.5 mm can body and radial leads allow space-efficient placement on through-hole PCBs.
• High-voltage capability: 250 V rating supports higher-voltage rails without upsizing capacitance or board area.
• Measured ripple specifications: Published LF and HF ripple currents (55 mA at 120 Hz, 88 mA at 10 kHz) enable engineers to size capacitors against real ripple-loading conditions.
• Predictable loss and leakage: Specified tan δ (0.2 at 20°C, 120 Hz) and 147 µA leakage current provide deterministic electrical behavior for design validation.
• Endurance-backed reliability: 2000 hours at 85°C endurance rating supports long-term performance expectations in temperature-limited environments.
• RoHS compliant: Meets RoHS requirements for use in restricted-substance environments and regulated assemblies.
