UFW1J332MRD

The UFW1J332MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, engineered for audio equipment. It delivers 3300 µF capacitance at a 63 V rating in a compact φ20 × 40 mm can, offering high ripple handling and long-term endurance for audio power systems and related electronics.

This polarized capacitor is optimized for applications that require bulk energy storage and smoothing in audio designs, combining a wide operating temperature range with specified low- and high-frequency ripple current capability.

Key Features

• Capacitance & Voltage — 3300 µF capacitance with a 63 V rated voltage and ±20% tolerance, suitable for mid-voltage audio power rails.
• Ripple Current Performance — Low-frequency ripple current of 2.7 A (120 Hz) and high-frequency ripple current of 3.105 A (10 kHz), enabling effective handling of both power-line and higher-frequency ripple components.
• Leakage Current — Specified leakage current of 6237 µA, provided to support design margin calculations and bias current budgets.
• Endurance & Temperature Range — Lifetime of 2000 hours at 85°C and an operating temperature range of −40°C to +85°C, providing predictable performance over extended warm-environment operation.
• Package & Mounting — Radial lead, can-style package (φ20 × 40 mm) with 10 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• Audio-Focused Series — Part of Nichicon’s UFW series (standard, for audio equipment) designed with audio system requirements in mind.
• Polarized Construction — Polarized electrolytic capacitor suitable for conventional DC filter and energy storage roles in audio circuits.

Typical Applications

• Audio Power Supplies — Bulk energy storage and smoothing on amplifier and audio-system power rails where 63 V rating and high capacitance are required.
• Professional and Consumer Audio Equipment — Power-filtering and decoupling in mixers, amplifiers, and other audio electronics that benefit from the UFW series design.
• Amplifier Power Stages — Support for transient power demands and ripple attenuation on amplifier supply lines.

Unique Advantages

• High Capacitance per Can — 3300 µF in a φ20 × 40 mm case provides substantial energy storage in a compact radial package.
• Dual-Frequency Ripple Capability — Specified ripple current at both 120 Hz and 10 kHz supports designs that must address both low- and high-frequency ripple components.
• Long-Term Endurance — Rated for 2000 hours at 85°C, enabling designers to specify performance over defined life conditions.
• Audio-Optimized Series — Part of the UFW family, explicitly designated for audio equipment, aligning series-level characteristics with audio design needs.
• Radial Lead Flexibility — Leads and package dimensions suited to through-hole assembly and repairable designs; packaging options support different production flows.
