UKL1A470KDD

The UKL1A470KDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UKL low-leakage series. It provides 47 µF capacitance at a 10 V rating with a compact φ5 × 11 mm can and 2 mm lead spacing for space-conscious, through-hole assemblies.

This part offers low leakage and defined ripple handling for low-voltage DC and audio-oriented circuits. Note: this part is End Of Life and is not recommended for new designs.

Key Features

• Capacitance & tolerance — 47 µF with ±10% (K) tolerance measured at 120 Hz, 20°C.
• Rated voltage — 10 V DC, polarized construction for DC filtering and coupling.
• Low leakage — Leakage current specified at 0.94 µA, suitable where minimal self-discharge and stable bias are required.
• Ripple current capability — 110 mA at 120 Hz (low frequency) and 220 mA at 10 kHz (high frequency) for decoupling and smoothing in low-voltage circuits.
• Endurance & temperature — Rated 2000 hours at 85°C; operating temperature range −40°C to 85°C.
• Compact radial package — φ5 × 11 mm can, radial lead mounting, 2 mm lead spacing with 0.5 mm tolerance; available in bulk or bag packing.
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• Audio circuits — Low leakage and defined ripple handling make this capacitor suitable for coupling and power-supply smoothing in compact audio stages.
• Low-voltage DC filtering — 10 V rating and polarized construction support local decoupling and rail stabilization on low-voltage boards.
• Compact board layouts — Small φ5 × 11 mm can and 2 mm lead spacing fit tight through-hole placements and densely populated PCBs.

Unique Advantages

• Low self-discharge: Specified leakage current of 0.94 µA helps maintain bias and reduces long-term drift in standby or low-current circuits.
• Frequency-aware ripple performance: Rated ripple currents at both 120 Hz and 10 kHz support performance across low- and high-frequency decoupling tasks.
• Space-efficient radial package: φ5 × 11 mm can with 2 mm lead spacing minimizes board area for through-hole implementations.
• Durability at elevated temperature: 2000 hours endurance at 85°C provides predictable lifetime behavior for sustained operation within the rated temperature range.
• Procurement-ready packaging: Available in bulk (no terminal forming) or bag packing to suit assembly and stock management needs.

Why Choose UKL1A470KDD?

UKL1A470KDD delivers a compact, low-leakage aluminum electrolytic option for designs that require stable bias, reliable decoupling, and constrained board space. Its 47 µF / 10 V specification, combined with measurable ripple ratings at both low and high frequencies, makes it well suited for audio and other low-voltage DC applications where leakage and footprint matter.

Although this part is End Of Life and not recommended for new designs, it remains an option for repair, legacy-support, or short-run production needs where the UKL series’ low-leakage characteristics and form factor are required.
