The UKW1J330MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, designed with audio and AV equipment in mind. It delivers 33 µF capacitance at a 63 V rating in a compact φ6.3 × 11 mm can, offering a balance of electrical performance and small footprint for audio circuits.

The UKW series emphasizes sound-quality characteristics enabled by a developed electrolyte and is RoHS compliant. Status: End Of Life.

Key Features

• Electrical Performance — 33 µF nominal capacitance with ±20% tolerance, rated for 63 V operation.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.10 measured at 20°C, 120 Hz (rating 63 V), supporting predictable AC behaviour in audio circuits.
• Ripple Handling — Low-frequency ripple current 140 mA at 120 Hz and high-frequency ripple capability up to 280 mA at 10 kHz, providing suitability for a range of ripple conditions.
• Leakage Current — Specified leakage current 62.37 µA (measurement conditions in product data).
• Reliability & Endurance — Rated endurance of 2000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage after the test.
• Mechanical & Packaging — Polarized radial-lead can in size φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Operating Range — Specified operating temperature range from −40°C to +85°C.
• RoHS Compliance — Compliant to RoHS directives as noted in the product series information.

Typical Applications

• Audio Equipment — Intended for use in audio and AV systems where compact radial electrolytic capacitors are required.
• Consumer AV Devices — Suited to small-form-factor AV and entertainment electronics that use polarized electrolytic capacitors.
• General Electronic Assemblies — Applicable wherever a 33 µF, 63 V polarized radial capacitor is specified and a compact footprint is beneficial.

Unique Advantages
