UKL1E330KED

The UKL1E330KED is a Nichicon UKL series aluminum electrolytic capacitor designed for low leakage applications. It is a radial‑lead, polarized can with 33 µF capacitance, a 25 V rated voltage and ±10% tolerance.

Key electrical characteristics include a low leakage current of 1.65 µA and ripple current ratings of 140 mA at 120 Hz and 280 mA at 10 kHz. The device is RoHS compliant and is specified for operation from –40 °C to 85 °C with an endurance rating of 2000 hours at 85 °C. Status: End Of Life; products in this series are scheduled for discontinuation and are not recommended for new designs.

Key Features

• Capacitance & Tolerance – 33 µF nominal capacitance with ±10% tolerance, suitable where defined charge storage and decoupling are required.
• Voltage Rating – 25 V rated voltage for mid‑range DC applications.
• Low Leakage Performance – Specified leakage current of 1.65 µA, enabling stable DC biasing in circuits sensitive to leakage.
• Ripple Current Capability – Low frequency ripple current 140 mA (120 Hz) and high frequency ripple current 280 mA (10 kHz), supporting both power‑supply smoothing and higher frequency decoupling tasks.
• Thermal & Endurance – Operates from –40 °C to 85 °C with a rated life of 2000 hours at 85 °C, providing predictable lifetime performance under specified conditions.
• Radial Through‑Hole Package – Compact φ6.3×11 mm can with 2.5 mm lead spacing (±0.5 mm) and radial leads for traditional through‑hole PCB mounting and easy replacement in existing assemblies.
• Packaging Options & Compliance – Available in bulk (no terminal forming) / bag packing and compliant with RoHS requirements.

Typical Applications

• Audio power‑supply smoothing – Use on audio amplifier and preamplifier power rails where 33 µF capacitance and 140 mA ripple handling at 120 Hz support stable supply filtering.
• Bias stabilization in audio circuits – Low leakage current (1.65 µA) helps preserve DC bias points in sensitive audio front‑end and preamp stages.
• High‑frequency decoupling for audio electronics – High frequency ripple rating of 280 mA at 10 kHz makes this part useful for decoupling applications in audio signal chains and support circuitry.

Unique Advantages

• Low leakage for stable DC performance: The specified 1.65 µA leakage current reduces bias drift in circuits where leakage matters.
• Dual ripple capability: Rated ripple currents at both 120 Hz and 10 kHz provide quantified performance across low and higher frequency domains.
• Compact radial can: φ6.3×11 mm size and 2.5 mm lead spacing enable space‑efficient through‑hole layouts and drop‑in replacements for legacy boards.
• Endurance rating: 2000 hours at 85 °C gives a clear specification for life expectancy under elevated temperature stress.
• RoHS compliance and standard packaging: Facilitates regulatory compliance and handling for production and repair operations.
