• Compact radial package — Can dimension φ12.5 × 25 mm with 12.5 mm lead spacing; radial lead mounting for through-hole assemblies.
• Packaging options — Available in bulk (no terminal forming) or bag packing.
• Lifecycle status — End of Life.

Typical Applications

• Audio equipment — Use in consumer and professional audio products where large capacitance supports consistent power delivery and sound quality.
• Audio power supplies — Bulk filtering and smoothing in audio power rails to help maintain stable supply under dynamic loads.
• Amplifier and preamplifier circuits — Energy storage and decoupling where high capacitance at low voltage is required.

Unique Advantages

• High bulk capacitance: 3300 µF provides substantive energy storage for low‑frequency stabilization in audio circuits.
• Designed for audio use: UFW series positioning and specified performance target applications where sound quality matters.
• High ripple handling: Rated ripple currents at both 120 Hz and 10 kHz accommodate typical audio power supply and regenerative loads.
• Wide operating range: −40 °C to +85 °C supports a broad set of environmental conditions for audio equipment deployment.
• Through-hole radial package: φ12.5×25 mm can with 12.5 mm lead spacing simplifies mechanical mounting and replacement in existing PCB layouts.
• Specified endurance: 2000 hours at 85 °C gives a defined thermal lifetime for reliability planning.
