UFW1E332MHD

The UFW1E332MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment and related electronic applications. It provides 3300 µF capacitance at a 25 V rating in a compact φ16 × 25 mm can with 7.5 mm lead spacing.

Engineered for reliability in power smoothing and audio circuits, this polarized capacitor delivers defined ripple handling, a controlled dissipation factor, and long endurance at elevated temperature for stable performance in embedded and consumer audio designs.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance at 25 V provides bulk energy storage and decoupling for power rails and audio circuits.
• Low-frequency and High-frequency Ripple Capability — Rated ripple currents of 1.95 A at 120 Hz and 2.243 A at 10 kHz support both mains-derived and higher-frequency ripple conditions.
• Loss Characteristics — Specified tanδ of 0.2 (DF) measured at 20°C, 120 Hz supports predictable dissipation behavior in audio-frequency circuits.
• Leakage Current — Rated leakage current of 2475 µA for controlled bias leakage in power and audio applications.
• Endurance — 2000 hours at 85°C life rating; capacitors meet specified capacitance, tanδ, and leakage limits after the endurance test when returned to 20°C.
• Temperature Range — Operating range of −40°C to +85°C for use across a wide set of environmental conditions.
• Package & Mounting — Radial lead can (φ16 × 25 mm) with 7.5 mm lead spacing; supplied in bulk or bag packing for through-hole assembly.
• Pb-free Leadwire and Sleeve Configuration — φ16 size uses the HD configuration (Pb-free leadwire and Pb-free PET sleeve) as defined in the UFW series configuration table.

Typical Applications

• Audio Power Supply Filtering — Bulk energy storage and smoothing for amplifier rails and preamp stages to reduce low-frequency ripple and maintain stable biasing.
• Power Decoupling — Local decoupling on PCB power planes where 25 V rating and high capacitance are required for transient suppression.
• Analog Signal Conditioning — Stabilization of supply nodes in audio signal chains where controlled dissipation and leakage characteristics are important.

Unique Advantages

• High Capacitance in a Compact Can — 3300 µF in a φ16 × 25 mm package conserves board space while delivering substantial energy storage.
• Dual-frequency Ripple Ratings — Specified ripple currents at both 120 Hz and 10 kHz allow designers to assess performance for mains-related and higher-frequency ripple scenarios.
• Measured Dissipation Factor — tanδ specified at 20°C, 120 Hz provides a clear metric for thermal and loss budgeting in audio circuits.
• Proven Endurance — 2000-hour rating at 85°C gives designers a defined lifetime metric for thermal and reliability planning.
• Radial Lead Convenience — Through-hole radial leads and standard 7.5 mm spacing simplify prototyping and retrofit into existing PCB layouts.
• Series Design for Audio — Part of Nichicon’s UFW series, specified for audio equipment applications and produced in mass-production status.
