UKL1H470KPD

The UKL1H470KPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low leakage series. It delivers 47 µF capacitance at 50 V in a compact φ8 × 11.5 mm can with a polarized radial lead configuration.

Designed for audio applications, this standard-type capacitor combines low leakage (4.7 µA), defined ripple handling (190 mA at 120 Hz and 380 mA at 10 kHz), and a 2000-hour endurance rating at 85 °C to support reliable power smoothing and decoupling in embedded audio circuits.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with ±10% tolerance at a rated voltage of 50 V, suitable for a wide range of DC filtering tasks.
• Low Leakage Current: Specified leakage current of 4.7 µA for minimized DC loss and stable long-term performance in bias-sensitive circuits.
• Ripple Current Performance: Low-frequency ripple current of 190 mA (120 Hz) and high-frequency ripple current of 380 mA (10 kHz) to handle both mains-derived and high-frequency ripple components.
• Endurance & Temperature: Rated for 2000 hours at 85 °C with an operating temperature range of −40 °C to +85 °C.
• Package & Mechanical: Radial can package with overall size φ8 × 11.5 mm, lead spacing 3.5 mm (±0.5 mm), and standard radial lead mounting for through-hole assemblies.
• Mounting & Polarity: Polarized aluminum electrolytic design for DC filtering and energy-storage tasks in power and audio circuits.
• Compliance & Packaging Options: RoHS compliant; supplied in bulk (no terminal forming) or bag packing to match assembly and inventory workflows.

Typical Applications

• Audio: Suitable for power smoothing, decoupling and energy-storage duties in audio equipment where low leakage and defined ripple handling improve performance and stability.

Unique Advantages

• Low DC leakage: The 4.7 µA leakage rating helps preserve bias and reduces unwanted DC loss in sensitive circuits.
• Defined ripple capability: Dual ripple specifications (190 mA at 120 Hz, 380 mA at 10 kHz) let designers account for both low- and high-frequency ripple when sizing decoupling networks.
• Compact radial form factor: φ8 × 11.5 mm can and 3.5 mm lead spacing deliver a small footprint for through-hole designs and retrofits.
• Elevated temperature endurance: 2000-hour rating at 85 °C supports sustained operation in warm environments common to enclosures and audio power stages.
• RoHS compliant and packaging flexibility: Meets RoHS requirements and is available in bulk or bag packing to suit production and stocking needs.
