UVK2A471MHD

The UVK2A471MHD is a miniature aluminum electrolytic capacitor in Nichicon’s UVK series, offered as a standard radial-lead, polarized device. Designed for general-purpose power circuitry, it provides 470 µF capacitance at a 100 V rating in a compact φ16 × 25 mm can.

Its combination of a high voltage rating, compact footprint, defined ripple-handling capability, and 2,000-hour endurance at 85°C makes it suited for power-smoothing, filtering, and energy-storage roles across industrial and electronic equipment where a reliable radial electrolytic is required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 100 V rated voltage and tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Compact Radial Can — Miniature φ16 × 25 mm case with radial lead mounting and 7.5 mm lead spacing (±0.5 mm), enabling compact board layouts for through-hole designs.
• Loss Characteristics — Dissipation factor tan δ = 0.08 (measured at 20°C, 120 Hz, rated voltage 100 V), offering controlled AC loss behavior for predictable performance.
• Ripple Current Capability — Rated for 1.0 A at 120 Hz (low frequency) and 1.5 A at 10 kHz (high frequency), suitable for power supply smoothing and decoupling under AC ripple stresses.
• Leakage Current — Specified leakage current of 1,410 µA (measured under standard conditions), supporting predictable DC leakage characteristics.
• Endurance & Temperature Range — Rated for 2,000 hours at 85°C; operating temperature range −40°C to +85°C. After the endurance test, capacitance change remains within ±20%, tan δ stays within 200% of initial specified value, and leakage current remains at or below the initial specification.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.

Typical Applications

• Power Supply Smoothing — Bulk capacitance for DC bus smoothing and voltage hold-up in general-purpose power supplies up to 100 V.
• Filtering and Decoupling — AC ripple filtering at both low (120 Hz) and higher frequency components (10 kHz) where measured ripple current ratings apply.
• Industrial and Consumer Electronics — General-purpose energy storage and transient absorption in control modules, appliances, and electronic assemblies requiring a 100 V polarized electrolytic.

Unique Advantages

• High Voltage Capability: 100 V rating provides margin for higher-voltage circuits while using a compact, miniature case.
• Measured Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz allow designers to match the component to expected AC stress and thermal conditions.
• Compact Footprint: φ16 × 25 mm can and 7.5 mm lead spacing enable space-efficient through-hole implementations without sacrificing capacitance.
• Proven Endurance: 2,000-hour life at 85°C with defined post-test limits on capacitance, tan δ, and leakage current supports predictable long-term behavior.
• RoHS Compliance and Packaging Options: Environmentally compliant and available in bulk or bag packing to suit production and prototyping needs.
