UKL1C470KED

The UKL1C470KED is an aluminum electrolytic capacitor from Nichicon's UKL series, engineered for low leakage current in a compact radial-lead package. With a capacitance of 47 µF at 16 V and a small φ6.3 × 11 mm can, it targets audio and related electronic applications that require stable decoupling and filtering in a space‑efficient form factor.

Key value comes from its low leakage characteristic, measurable ripple-handling capability across low and high frequencies, RoHS compliance, and a defined endurance rating for elevated-temperature operation.

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with ±10% tolerance at 120 Hz, 20°C, providing predictable charge storage for filtering and decoupling.
• Rated Voltage — 16 V DC rating suitable for low-voltage audio and auxiliary power rail applications.
• Low Leakage Current — Specified leakage current of 1.504 µA, minimizing standby loss and drift in bias-sensitive circuits.
• Ripple Current Performance — Low-frequency ripple current of 140 mA at 120 Hz and high-frequency ripple current of 280 mA at 10 kHz, supporting both mains‑synchronous and higher-frequency ripple conditions.
• Endurance & Temperature — Rated for 2000 hours at 85°C with an operating temperature range of –40°C to 85°C, enabling predictable lifetime behavior under defined thermal stress.
• Package & Mounting — Radial lead, polarized aluminum can (φ6.3 × 11 mm) with 2.5 mm lead spacing (±0.5 mm), suited to through‑hole assembly and hand or wave soldering workflows.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and handling.
• Product Lifecycle — End Of Life status; the part is scheduled for discontinuation and is not recommended for new designs.

Typical Applications

• Audio — Intended for use in audio circuits where low leakage and compact radial packaging support power-rail filtering and decoupling.

Unique Advantages

• Low standby leakage — 1.504 µA leakage current helps maintain circuit bias and reduces quiescent loss in sensitive audio front ends.
• Frequency-aware ripple handling — Separate low- and high-frequency ripple current ratings (140 mA @120 Hz, 280 mA @10 kHz) let designers match the capacitor to expected ripple spectra.
• Compact through-hole form — φ6.3 × 11 mm radial can with 2.5 mm lead spacing saves board area while remaining compatible with standard through‑hole assembly.
• Defined thermal endurance — 2000 hours at 85°C provides a clear baseline for lifetime planning under elevated operating temperatures.
• Regulatory compliance — RoHS compliance supports deployments where restricted‑substance conformance is required.
• Flexible packaging — Available in bulk or bag packing to suit volume handling and assembly preparation needs.

Why Choose UKL1C470KED?

UKL1C470KED positions itself as a compact, low‑leakage radial electrolytic capacitor for audio-focused designs that require predictable ripple performance and a defined thermal endurance. Its combination of 47 µF capacitance, 16 V rating, and measured leakage current makes it suitable for power-rail filtering and bias maintenance in space‑constrained through‑hole assemblies.

Note that this part is End Of Life and scheduled for discontinuation; it is therefore best suited for existing designs or replacement needs where the lifecycle is understood. For ongoing new-design projects, consider lifecycle and availability planning based on this status.
