UVK1E471MPD

The UVK1E471MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series, offering 470 µF capacitance at a 25 V rating in a compact φ10 × 12.5 mm can. Designed for general-purpose circuit applications, it combines a small footprint with defined ripple handling and long-term endurance for use in power filtering and decoupling on compact boards.

Key value propositions include a tight form factor with 5 mm lead spacing, RoHS compliance, and specified performance data for ripple current, leakage, dissipation factor, and an endurance rating of 2000 hours at 85°C.

Key Features

• Capacitance & Tolerance — 470 µF nominal with a capacitance tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Voltage Rating — Rated for 25 V operation.
• Compact Radial Package — Miniature aluminum can package with dimensions φ10 × 12.5 mm and 5 mm lead spacing in a radial-lead mounting style.
• Ripple Current Capability — Rated low-frequency ripple current of 550 mA at 120 Hz and high-frequency ripple current of 825 mA at 10 kHz, specified for smoothing and filtering duties.
• Low Leakage — Specified leakage current of 352.5 µA after rated conditions, suitable for general-purpose power circuits.
• Dissipation Factor (tan δ) — tan δ of 0.16 measured at 20°C, 120 Hz, supporting predictable ESR behavior in design calculations.
• Operating Temperature & Endurance — Rated for -40°C to +85°C operation with an endurance of 2000 hours at 85°C.
• Regulatory — RoHS compliant.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly handling.

Typical Applications

• Power Supply Filtering — Provides bulk capacitance and ripple handling for DC power rails where 470 µF at 25 V is required, using the radial-lead form for through-hole assemblies.
• Embedded and Control Boards — Compact φ10 × 12.5 mm package and 5 mm lead spacing make it suitable for space-constrained control and embedded systems requiring reliable capacitance and endurance.
• Consumer and Industrial Electronics — General-purpose smoothing and decoupling in consumer and industrial circuits within the -40°C to +85°C operating range.

Unique Advantages

• Space-efficient form factor: The miniature φ10 × 12.5 mm can and 5 mm lead spacing reduce board area for designs with limited clearance.
• Measured ripple performance: Explicit ripple current ratings at 120 Hz and 10 kHz (550 mA and 825 mA) allow designers to select the part with known AC handling capability.
• Predictable electrical loss: Specified tan δ of 0.16 at 20°C, 120 Hz provides a referenced dissipation factor for thermal and ESR considerations.
• Defined leakage behavior: Leakage current specified at 352.5 µA supports predictable standby and quiescent current budgeting.
• Proven endurance: 2000 hours at 85°C endurance rating supports designs requiring long-term stability at elevated temperature.
• Regulatory compliance: RoHS compliance for use in products that require restricted-substance conformity.
