UVZ1E4R7MDD

The UVZ1E4R7MDD is a compact radial-lead aluminum electrolytic capacitor in Nichicon's UVZ series, specified at 4.7 µF and 25 V. Designed for general-purpose electronic circuits, it combines a small can package with defined electrical characteristics for consistent performance.

Key value propositions include a wide operating temperature range (–55°C to 105°C), low leakage current, and a rated endurance of 1000 hours at 105°C, making it suitable where stable capacitance, predictable loss characteristics, and compact through-hole mounting are required.

Key Features

• Electrical characteristics 4.7 µF nominal capacitance at 25 V rated voltage with capacitance tolerance of -20% to +20% and polarization for DC applications.
• Loss and leakage Tangent of loss angle (tanδ) 0.16 measured at 20°C, 120 Hz, and a leakage current of 4 µA for low standby drain.
• Ripple current handling Low-frequency ripple current 25 mA at 120 Hz and high-frequency ripple current 50 mA at 10 kHz, enabling defined AC stress handling across frequencies.
• Reliability and lifetime Endurance specified as 1000 hours at 105°C; designed to retain capacitance within ±20% after the rated test duration.
• Mechanical and packaging Compact radial can, size φ5 × 11 mm (D × L), lead spacing 2 mm with ±0.5 mm tolerance, available in bulk (no terminal forming) or bag packing.
• Temperature range Wide operating range from –55°C to 105°C per series specification.
• Regulatory RoHS compliant.

Typical Applications

• General-purpose electronics — Suited for general-purpose circuits that require a compact radial-lead aluminum electrolytic capacitor.
• Through-hole PCB assemblies — Radial-lead format and 2 mm lead spacing align with standard through-hole board layouts and prototyping processes.
• Wide-temperature designs — The –55°C to 105°C operating range supports use in designs exposed to broad temperature variations.

Unique Advantages

• Compact form factor: φ5 × 11 mm can fits into tight board spaces while providing 4.7 µF capacitance at 25 V.
• Predictable loss behavior: Specified tanδ (0.16 at 20°C, 120 Hz) gives designers a clear basis for AC and impedance calculations.
• Low leakage current: 4 µA leakage helps minimize standby current in low-power and general-purpose circuits.
• Frequency-aware ripple specifications: Defined ripple current values at 120 Hz and 10 kHz support design decisions for both low- and high-frequency ripple environments.
• Robust operating envelope: 1000 hours endurance at 105°C and a wide temperature range support long-term stability in demanding environments.
• Assembly-friendly packaging: Bulk or bag packing and standard lead spacing ease handling for prototype runs and production.
