UKL0J332KHD

The UKL0J332KHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, designed for low leakage current and bulk energy storage in audio-focused electronics. It provides 3.3 mF (3300 µF) capacitance at a 6.3 V rating in a compact φ16 × 25 mm can with 7.5 mm lead spacing.

This part is listed as End Of Life and the UKL series is scheduled for discontinuation; it is therefore appropriate for maintenance, repair, or legacy designs where the specified characteristics are required.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) nominal capacitance with ±10% tolerance at 6.3 V, providing substantial bulk storage for low-voltage power rails.
• Low Leakage Current — Standard low-leakage UKL series construction with a listed leakage current of 41.58 µA, suitable where minimal standby drain is important.
• Ripple Current Performance — Rated low-frequency ripple current of 1.27 A at 120 Hz and high-frequency ripple current of 1.46 A at 10 kHz to support decoupling under varying load conditions.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C with an operating temperature range of −40°C to +85°C; endurance specification includes capacitance retention consistent with the UKL series requirements.
• Radial Lead Package — Polarized radial-lead can (φ16 × 25L) with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward assembly.
• Packaging & Compliance — Available in bulk (no terminal forming) or bag packing and RoHS compliant.

Typical Applications

• Audio Equipment — Bulk energy storage and power-rail smoothing in audio amplifiers and consumer audio electronics where low leakage and robust capacitance are needed.
• Power Supply Filtering — Decoupling and filtering on low-voltage DC rails that require large capacitance in a compact, through-hole package.
• Repair and Maintenance — Replacement part for legacy or existing designs that specified UKL-series low-leakage electrolytics.

Unique Advantages

• High Bulk Capacitance at Low Voltage — 3.3 mF at 6.3 V provides significant charge storage for smoothing and transient support on low-voltage rails.
• Low Standby Drain — Low leakage current (41.58 µA) reduces parasitic discharge in standby conditions and helps preserve battery life in portable audio applications.
• Robust Ripple Handling — Specified ripple current ratings at both 120 Hz (1.27 A) and 10 kHz (1.46 A) accommodate a range of switching and linear power environments.
• Through-Hole Durability — Radial-lead can construction with defined lead spacing simplifies mechanical mounting and rework for serviceable boards.
• Proven Endurance — 2000-hour endurance at 85°C supports reliable operation under elevated ambient temperatures typical of enclosed audio electronics.
• Regulatory Compliance — RoHS-compliant construction aligns with common regulatory requirements for electronic assemblies.

Why Choose UKL0J332KHD?

The UKL0J332KHD delivers a combination of large capacitance, low leakage, and defined ripple performance in a compact radial-lead package, making it well suited to audio and low-voltage filtering roles in service and repair scenarios. Its 2000-hour endurance at 85°C and operating range from −40°C to +85°C provide predictable behavior in a variety of environmental conditions.

Because this part is listed as End Of Life and the UKL series is scheduled for discontinuation, UKL0J332KHD is particularly appropriate for maintaining or repairing existing designs that require the specific UKL-series characteristics rather than for new product introductions.
