UKW1J331MPD

The UKW1J331MPD is a Nichicon UKW-series aluminum electrolytic capacitor in a radial-lead can, specified at 330 µF and 63 V. It is part of the UKW family developed for audio and AV equipment, incorporating a formulated electrolyte to realize a harmonious balance of sound quality.

Designed for through-hole mounting, this part combines high ripple capability, a compact φ10 × 20 mm can size with 5 mm lead spacing, and endurance for sustained operation at elevated temperature.

Key Features

• Electrical Performance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz; rated voltage 63 V for higher supply rails.
• Ripple Handling — Rated ripple current of 650 mA at 120 Hz and 975 mA at 10 kHz, suitable for applications with significant AC ripple across the capacitor.
• Leakage Current — Specified leakage current of 623.7 µA, as provided in the product data.
• Audio-Optimized Electrolyte — UKW-series formulation aimed at achieving a harmonious balance of sound quality, specifically targeted for audio and AV equipment.
• Reliability & Endurance — Endurance rating of 2000 hours at 85°C with rated voltage applied, meeting the UKW series endurance specification when restored to 20°C.
• Mechanical & Mounting — Radial lead, aluminum can package (φ10 × 20 mm) with 5 mm lead spacing; supplied in bulk/bag packaging and available for mass production.
• Operating Temperature — Specified for operation from −40°C to +85°C.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Audio Equipment — Intended for use in audio circuits where the UKW-series electrolyte formulation contributes to sound quality.
• AV Equipment — Suited for AV system power domains and signal-related circuits in consumer and professional AV products.
• Power Filtering in Audio Systems — Employed for smoothing and decoupling in amplifier and power-supply sections within audio/AV designs to handle ripple currents at both low and high frequencies.

Unique Advantages

• Audio-Focused Electrolyte: UKW-series formulation developed to achieve a harmonious balance of sound quality, addressing audio-centric design priorities.
• High Voltage Capability: 63 V rating enables use on higher supply rails within audio and AV equipment designs.
• Broad Ripple Performance: Dual ripple specifications—650 mA at 120 Hz and 975 mA at 10 kHz—support both low-frequency smoothing and higher-frequency decoupling demands.
• Proven Endurance: 2000 hours at 85°C under rated voltage delivers predictable lifetime behavior for sustained thermal and electrical stress.
• Compact Through-Hole Package: φ10 × 20 mm can and 5 mm lead spacing provide a small footprint for through-hole layouts while keeping required capacitance and ripple handling.
• RoHS Compliance: Meets environmental directive requirements for restricted substances.
