UVK2E470MHD

The UVK2E470MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series, designed for general-purpose power filtering and decoupling in compact assemblies. This miniature-sized capacitor provides 47 µF capacitance at a 250 V rating with a compact φ12.5×20L can and 5 mm lead spacing.

Engineered for reliability in elevated-temperature environments, the part offers a 2000-hour endurance at 85°C, RoHS compliance, and measurable electrical characteristics—making it suitable for a wide range of industrial and electronic designs that require a small, high-voltage electrolytic solution.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a 250 V rated voltage for DC filtering and energy storage in higher-voltage circuits.
• Compact Radial Package: Miniature-sized UVK can with dimensions φ12.5×20L and radial leads; lead spacing 5 mm with 0.5 mm tolerance for straightforward through-hole mounting.
• Endurance & Temperature: Rated for operation from −40°C to 85°C with a life specification of 2000 hours at 85°C under rated voltage.
• Ripple Current Capability: Low-frequency ripple current 270 mA at 120 Hz and high-frequency ripple current 432 mA at 10 kHz to support smoothing in power supplies across frequencies.
• Low Leakage & Dissipation Factor: Specified leakage current of 570 µA and a dissipation factor (tan δ) of 0.20 measured at 20°C, 120 Hz, for predictable loss performance.
• Polarized Radial Lead: Polarized aluminum electrolytic design with standard radial-lead mounting for general-purpose PCB integration.
• Packaging Options & Production Status: Available in bulk (no terminal forming) or bag packing; part is in mass production and RoHS compliant.

Typical Applications

• Industrial Power Supplies — DC smoothing and bulk decoupling where a compact 250 V electrolytic is required for higher-voltage rails.
• General-Purpose Electronics — Energy storage and filtering in control circuitry and consumer devices requiring a small footprint and reliable endurance.
• Switching Power Converters — Output filtering and ripple attenuation at both low and high frequencies, leveraging specified ripple current ratings at 120 Hz and 10 kHz.

Unique Advantages

• Miniature footprint: φ12.5×20L construction and UVK series “one rank smaller” case sizing enable tighter board layouts without sacrificing voltage rating.
• High-voltage capability: 250 V rating supports higher-voltage DC rails while maintaining a modest capacitance for space-constrained designs.
• Designed for elevated temperatures: 2000-hour endurance at 85°C provides quantified reliability for applications with sustained thermal stress.
• Frequency-flexible ripple handling: Separate ripple current specifications at 120 Hz and 10 kHz help designers assess performance across switching and line-frequency conditions.
• Predictable electrical loss and leakage: Specified tan δ (0.20 at 20°C/120 Hz) and leakage current (570 µA) enable accurate thermal and leakage budgeting in system designs.
• Supply readiness: Mass-production status and standard bulk/bag packaging simplify procurement and volume deployment.
