• High Ripple Current — Rated ripple current of 750 mA at 100 kHz and 375 mA at 120 Hz, enabling effective smoothing and decoupling in high-frequency power circuits.
• Leakage Performance — Specified leakage current of 758 µA; datasheet leakage limit reference: 0.04CV + 100 (µA).
• Temperature & Endurance — Operating temperature range −25 °C to +105 °C with a rated load life of 12,000 hours at 105 °C.
• Package & Mounting — Radial lead, can package with 7.5 mm lead spacing, nominal dimensions L: 20 mm × D: 18 mm and a seated height maximum of 20 mm for compact PCB implementations.
• Polarized — Polarized aluminum electrolytic construction for DC power applications.
• Compliance — RoHS compliant; part of Nichicon’s UCA series.
• Product Status — This product is scheduled for discontinuation and is not recommended for new designs.

Typical Applications

• Power Supplies — Bulk filtering and smoothing on high-voltage DC rails where 350 V rating and high ripple capability are required.
• Ballasts — Energy-storage and ripple-management duties in ballast circuits, leveraging the high-frequency ripple rating.
• General-Purpose High-Voltage Filtering — General-purpose circuits that require a compact 47 µF, 350 V polarized solution with long life at elevated temperature.

Unique Advantages

• High-frequency ripple handling: 750 mA rating at 100 kHz supports demanding high-frequency power smoothing tasks.
• Long operational life at elevated temperature: 12,000 hours at 105 °C provides predictable endurance in thermally stressed environments.
• Compact radial-can form factor: Small footprint (L: 20 mm × D: 18 mm) and 7.5 mm lead spacing simplify board layout for high-voltage designs.
• Clear leakage specification: Specified leakage current (758 µA) and datasheet leakage formula allow accurate power-loss and standby-current budgeting.
• RoHS compliance: Meets RoHS directive requirements for environmental conformity in applicable builds.
• Series-level pedigree: Part of Nichicon’s UCA family, providing consistent mechanical and electrical characteristics for like-for-like replacements within the series.

Why Choose UCA2V470MHD6?

The UCA2V470MHD6 is positioned for designs that require a compact, high-voltage polarized capacitor with strong ripple-current capability and long life at elevated temperatures. Its combination of 47 µF at 350 V, 750 mA ripple rating at 100 kHz, and 12,000-hour endurance at 105 °C make it appropriate for power-supply smoothing and ballast applications where those specific electrical and thermal attributes are required.

Please note the product is scheduled for discontinuation and is not recommended for new designs; it remains an option for maintenance, legacy production, or qualification of existing designs that require the UCA series characteristics.
