UFW1H682MRD

The UFW1H682MRD is a radial-lead aluminum electrolytic capacitor from the Nichicon UFW series designed for audio equipment. It provides high bulk capacitance (6.8 mF) and a 50 V rating in a compact φ16 × 35.5 mm aluminum can, delivering energy storage and smoothing suitable for demanding audio circuits.

Engineered for endurance and practical PCB assembly, this polarized radial component offers a wide operating temperature range and specified ripple current performance for AC waveform environments common in audio power stages.

Key Features

• High Capacitance — 6.8 mF (6800 µF) nominal capacitance for bulk energy storage and smoothing in power stages.
• Rated Voltage — 50 V working voltage to provide margin for higher-voltage audio and amplifier power rails.
• Ripple Current Performance — Specified ripple handling of 3.5 A at 120 Hz and 4.025 A at 10 kHz to support AC-loaded applications and minimize heating under ripple conditions.
• Endurance — 2000 hours at 85°C life rating, with post-test limits of ±20% capacitance change, tan δ within 200% of initial, and leakage current within initial limits.
• Temperature Range — Rated for operation from -40°C to +85°C to cover typical ambient conditions for audio equipment.
• Package and Mounting — Radial lead, polarized aluminum can with 7.5 mm lead spacing for through-hole PCB mounting; supplied bulk (no terminal forming) in bag packing.
• Tolerance and Loss — ±20% capacitance tolerance and specified tan δ (0.30 at 120 Hz, 20°C) for predictable performance in audio circuits.
• Product Status — End Of Life. Please verify availability and consider lead-time when planning production builds.

Typical Applications

• Audio Equipment — Bulk energy storage and smoothing for power supplies and amplifier rails in audio systems, leveraging large capacitance and ripple handling.
• Power Filtering for Amplifiers — Decoupling and reservoir applications where sustained ripple current capacity and 50 V rating are required.
• Consumer and Pro Audio Electronics — Through-hole assemblies requiring robust electrolytic capacitance and simple radial mounting for serviceability and repairability.

Unique Advantages

• Substantial Energy Storage: 6.8 mF nominal capacitance provides significant reservoir capability for transient load support and low-frequency smoothing.
• High Ripple Endurance: Rated ripple currents at both low and high frequencies (3.5 A at 120 Hz, 4.025 A at 10 kHz) reduce thermal stress in AC-loaded circuits.
• Thermal Durability: 2000 hours endurance at 85°C supports reliable operation under elevated temperature conditions typical in audio enclosures.
• Through-Hole Simplicity: Radial lead format with 7.5 mm lead spacing simplifies PCB layout and assembly for repairable designs.
• Compact Can Size: φ16 × 35.5 mm aluminum can provides a high capacitance-per-volume solution for constrained layouts.
• Supply Considerations: Bulk/bag packing option supports volume assembly and handling; product status is End Of Life, enabling planning for replacement or final builds.
