UVK1A472MHD

The UVK1A472MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UVK series, offered in a radial-lead can. It provides 4700 µF (4.7 mF) of polarized capacitance at a 10 V rating in a compact φ12.5 × 25 mm can with 5 mm lead spacing.

Designed for general-purpose electronic applications, this standard-type capacitor delivers high capacitance in a small footprint with a rated operating range of –40°C to 85°C and an endurance specification of 2000 hours at 85°C.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with a 10 V rated voltage and ±20% tolerance.
• Performance: Ripple Current — Low-frequency ripple current of 1.8 A (120 Hz) and high-frequency ripple current of 2.07 A (10 kHz) to support load variations within its ratings.
• Electrical Characteristics — Specified dissipation factor (tan δ) of 0.3 (measured at 20°C, 120 Hz) and a listed leakage current of 1410 µA.
• Reliability & Endurance — Rated life of 2000 hours at 85°C; endurance characterized by capacitance within ±20%, tan δ within specified limits, and leakage current not exceeding initial specified value after life test.
• Package & Mounting — Radial lead, can-style package (φ12.5 × 25 mm) with 5 mm lead spacing (±0.5 mm); supplied in bulk (no terminal forming) or bag packing.
• Operating Environment — Wide operating temperature range from –40°C to 85°C; RoHS compliant.

Typical Applications

• General Purpose Electronics — For designs requiring a 4700 µF, 10 V polarized aluminum electrolytic capacitor in a compact radial-lead package.
• Board-Level Bulk Capacitance — Suitable where compact, high-value capacitance is needed on a PCB with radial-lead mounting and 5 mm lead spacing.
• RoHS-Compliant Designs — Applicable to projects and assemblies that require components compliant with RoHS directive.

Unique Advantages

• High Capacitance in a Miniature Case — 4700 µF packaged in a φ12.5 × 25 mm can provides substantial bulk capacitance while minimizing board area.
• Dual-Frequency Ripple Capability — Specified ripple performance at both 120 Hz and 10 kHz (1.8 A and 2.07 A respectively) offers predictable behavior across common ripple spectra.
• Long Endurance at Elevated Temperature — Rated for 2000 hours at 85°C, supporting longer-term operation within the specified temperature rating.
• Polarized Radial-Lead Format — Through-hole radial leads and standard lead spacing simplify mounting and manual or wave-solder assembly workflows.
• RoHS Compliant — Meets RoHS requirements for restricted substances, aiding regulatory compliance for assemblies.
• Flexible Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production and prototyping needs.
