The UVK1E472MHD is a radial lead, miniature aluminum electrolytic capacitor from Nichicon’s UVK series. It provides 4700 µF of polarized capacitance at a rated voltage of 25 V in a compact φ16 × 25 mm can suitable for general-purpose electronic designs.

Designed for applications that require bulk energy storage and ripple handling in a compact radial package, this capacitor offers defined ripple current ratings, a broad operating temperature range, and a 2000-hour endurance rating at 85°C for reliable long-term operation.

Key Features

• Capacitance & Voltage  4700 µF (4.7 mF) nominal capacitance with a rated voltage of 25 V, suitable for bulk filtering and smoothing in general-purpose circuits.
• Package & Mounting  Radial lead, can-style package (φ16 × 25 mm) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Ripple Current Capability  Low-frequency ripple current 2.2 A at 120 Hz and high-frequency ripple current 2.53 A at 10 kHz, enabling effective attenuation of AC components across a range of frequencies.
• Loss & Leakage Characteristics  Tangent of loss angle (tan δ) 0.22 measured at 20°C and 120 Hz, and leakage current specified at 3525 µA, useful for assessing dissipation and standby behavior.
• Temperature & Endurance  Operating temperature range −40°C to +85°C with an endurance rating of 2000 hours at 85°C, meeting defined lifetime stability requirements when used within these limits.
• Tolerance & Polarization  Capacitance tolerance −20% to +20%; polarized device for DC applications requiring electrolytic bulk capacitance.
• Compliance & Production Status  RoHS compliant and currently in mass production for consistent availability.

Typical Applications

• General-purpose electronic equipment  Bulk energy storage and filtering where a compact radial aluminum electrolytic capacitor is required.
• Power supply smoothing  Smoothing and decoupling in DC power rails, leveraging the capacitor’s 4700 µF capacity and ripple current ratings.
• Decoupling across frequency ranges  Handling both low-frequency and higher-frequency ripple with specified ripple current performance at 120 Hz and 10 kHz.

Unique Advantages

• High bulk capacitance in a compact can  4700 µF in a φ16 × 25 mm package reduces board area while providing substantial energy storage for smoothing and hold-up.
• Measurable ripple handling  Defined low- and high-frequency ripple current ratings (2.2 A @120 Hz and 2.53 A @10 kHz) allow straightforward thermal and ripple budgeting in designs.
• Rated endurance at elevated temperature  2000 hours at 85°C provides a quantifiable lifetime expectation for designs that operate in warm environments.
• Clear electrical loss and leakage data  Specified tan δ (0.22 at 20°C/120 Hz) and leakage current (3525 µA) enable predictable dissipation and standby current calculations.
• Flexible packaging options  Available in bulk (no terminal forming) or bag packing to suit different assembly workflows and handling requirements.
• Regulatory compliance  RoHS compliance supports use in products targeted for regulated markets.
