UKL1J331KHD

The UKL1J331KHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKL series designed for low leakage current and through-hole applications. It delivers 330 µF at a 63 V rating with ripple performance suited to audio and power-filtering circuits where stable bias and low standby loss matter.

Packaged in a φ12.5 × 25 mm can with 5 mm lead spacing, this component targets audio equipment and other electronic designs requiring bulk decoupling, smoothing, and robust ripple handling over a -40°C to 85°C operating range.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with specified capacitance tolerance of ±20%.
• Voltage Rating — Rated for 63 V operation, suitable for higher-voltage audio and general-purpose power circuits.
• Low Leakage Current — Specified leakage current of 41.58 µA, helping reduce standby loss and maintain bias stability.
• Ripple Current Capability — Handles 710 mA at 120 Hz (low frequency) and 1.065 A at 100 kHz (high frequency), supporting both power supply smoothing and higher-frequency decoupling tasks.
• Endurance — Rated life of 2000 hours at 85°C, providing predictable performance under elevated operating temperatures.
• Operating Temperature Range — Specified for -40°C to 85°C to cover a wide range of environmental conditions.
• Radial Through-Hole Package — φ12.5 × 25 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm), suitable for standard PCB hole mounting and manual or automated insertion.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.
• Polarized — Electrolytic, polarized construction for DC power and filtering applications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production or prototyping needs.

Typical Applications

• Audio Power Supplies — Bulk decoupling and smoothing in amplifiers and audio power rails where stable voltage and low leakage are important.
• Audio Signal Systems — Power filtering for consumer and professional audio equipment to maintain low-noise supply rails.
• Professional Audio Equipment — Support for supply stability and ripple suppression in mixers, preamps, and related gear.

Unique Advantages

• Low Standby Loss: The low leakage current (41.58 µA) helps preserve bias and reduces idle power dissipation in audio and power-supply circuits.
• High-Voltage Capability: 63 V rating allows use in higher-voltage sections of designs where greater headroom is required.
• Broad Ripple Handling: Defined ripple ratings at both low (710 mA @120 Hz) and high frequencies (1.065 A @100 kHz) provide confidence for filtering across audio and switching domains.
• Compact Radial Form Factor: φ12.5 × 25 mm can with 5 mm lead spacing offers a compact through-hole solution for PCB power stages and serviceable audio assemblies.
• Durable Under Heat: 2000-hour endurance at 85°C supports longer-term operation in elevated-temperature environments.
• RoHS Compliance: Meets RoHS requirements to simplify environmental compliance in product designs.
