UKL1J331MHD

The UKL1J331MHD is a radial-lead aluminum electrolytic capacitor offering 330 µF capacitance at a 63 V rating. Designed as part of Nichicon’s UKL low-leakage series, it targets audio and other electronic applications that benefit from low leakage, defined ripple performance, and a compact radial-can form factor.

This unit provides targeted electrical performance with low-frequency and high-frequency ripple current ratings, a 2000-hour endurance rating at 85°C, and a temperature range of –40°C to 85°C, making it suitable for through-hole designs that require stable decoupling and energy storage characteristics.

Key Features

• Electrical Capacity — 330 µF capacitance with a tolerance of ±20%, polarized for conventional electrolytic use.
• Rated Voltage — 63 V rating for mid-voltage DC applications.
• Low Leakage Current — Specified leakage current of 41.58 µA, aligning with the UKL series’ focus on low leakage performance.
• Ripple Current Performance — Low-frequency ripple current 710 mA (120 Hz) and high-frequency ripple current 1.065 A (10 kHz) to support both power-supply smoothing and higher-frequency decoupling roles.
• Reliability and Endurance — Rated for 2000 hours at 85°C under applied rated voltage, supporting predictable life-cycle planning.
• Operating Range — Temperature range from –40°C to +85°C for a range of ambient conditions.
• Mechanical and Mounting — Radial lead, can package with dimensions φ12.5 × 25 mm and 5 mm lead spacing (±0.5 mm), suitable for through-hole PCB assembly.
• Packaging and Compliance — Available in bulk (no terminal forming) or bag packing; RoHS compliant.

Typical Applications

• Audio circuitry — Filtering, decoupling and energy storage in audio equipment, leveraging the capacitor’s low leakage and specified ripple performance.

Unique Advantages

• Low leakage for stable biasing: The UKL series low-leakage characteristic and the part’s 41.58 µA specification help preserve DC bias and reduce standby current impact in sensitive circuits.
• Defined ripple handling at multiple frequencies: With 710 mA at 120 Hz and 1.065 A at 10 kHz, the capacitor supports both traditional power-supply smoothing and higher-frequency decoupling needs.
• Long endurance at elevated temperature: 2000 hours at 85°C under rated voltage provides predictable life performance for thermal design planning.
• Compact radial can footprint: φ12.5 × 25 mm size with 5 mm lead spacing simplifies substitution into existing through-hole layouts and repair contexts.
• RoHS compliant packaging options: Offered in bulk or bag packing to suit production or service requirements while meeting RoHS directives.
• Polarized, through-hole convenience: Radial lead construction enables reliable soldering and mechanical retention for hand-assembly and wave-solder processes.
