UVK1A471MED

The UVK1A471MED is a miniature, standard-type aluminum electrolytic capacitor in Nichicon’s UVK series. It is a polarized, radial-lead can designed for general-purpose through-hole applications that require compact bulk capacitance.

With a nominal capacitance of 470 µF at 10 V, a wide operating temperature range of -40 °C to 85 °C, specified ripple current ratings, and a 2000-hour endurance at 85 °C, this part targets designs that need reliable, space-efficient electrolytic capacitance and RoHS-compliant materials.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a 10 V rated voltage with a tolerance of -20% to +20%.
• Compact Radial Can — Radial, can-style package with lead spacing of 2.5 mm and overall dimensions L: 1.1 × D: 0.63 cm; seated height maximum 1.1 cm for space-constrained boards.
• Polarized Radial Lead — Polarized capacitor with radial leads for through-hole mounting and straightforward PCB placement.
• Ripple Current Ratings — Rated ripple current of 350 mA at 120 Hz and 525 mA at 10 kHz to support AC ripple handling in low-voltage circuits.
• Temperature & Endurance — Operating temperature range from -40 °C to 85 °C; endurance specification of 2000 hours at 85 °C (after which capacitance change, tan δ, and leakage meet the series’ defined limits).
• Environmental Compliance — RoHS compliant materials and manufacturing.

Typical Applications

• General-purpose electronics — Intended for general-purpose circuits where a compact, polarized electrolytic capacitor is required on a through-hole PCB.
• Through-hole power modules — Suited for low-voltage, through-hole assemblies that require bulk capacitance in a small footprint.
• Consumer and industrial devices — Useful in equipment that benefits from miniature electrolytic capacitance with rated ripple performance and defined thermal endurance.

Unique Advantages

• High capacitance in a small package: 470 µF in a miniature radial can (L: 1.1 × D: 0.63 cm) saves PCB space while providing significant bulk capacitance.
• Measured ripple capability: Specified ripple current ratings at 120 Hz and 10 kHz allow designers to match the part to expected AC stress conditions.
• Defined thermal endurance: 2000 hours at 85 °C with documented post-test criteria (capacitance change and leakage limits) supports predictable long-term behavior.
• Easy through-hole implementation: Radial lead spacing (2.5 mm) and polarized lead configuration simplify placement and polarity control on PCBs.
• Regulatory compliance: RoHS compliance supports use in designs targeting restricted-substance requirements.
