UFW1C682MHD

The UFW1C682MHD is a Nichicon UFW series aluminum electrolytic capacitor in a radial‑lead can, offering 6800 µF capacitance at a 16 V rating with ±20% tolerance. It is designed for audio-oriented applications that require substantial energy storage, high ripple current handling, and reliable performance across a wide temperature range.

Key attributes include low-frequency ripple capability of 2.5 A at 120 Hz, high-frequency ripple handling up to 2.875 A at 10 kHz, a rated operating range from -40°C to 85°C, and endurance specified to 2000 hours at 85°C.

Key Features

• Capacitance & Voltage: 6800 µF nominal capacitance at 16 V provides significant bulk energy storage for supply smoothing and reservoir functions.
• Tight Tolerance & Loss Factor: ±20% capacitance tolerance with tan δ = 0.3 measured at 20°C and 120 Hz, offering predictable AC performance for audio power circuits.
• High Ripple Current Handling: Rated ripple currents of 2500 mA at 120 Hz (low frequency) and 2875 mA at 10 kHz (high frequency) to support demanding dynamic loads.
• Leakage Current: Specified leakage current of 3264 µA, allowing designers to account for DC loss in power budgets and bias networks.
• Endurance & Temperature Range: 2000 hours life at 85°C and an operating temperature range of -40°C to 85°C for reliable long-term operation in thermally stressed environments.
• Radial Can Package: Compact φ16 × 35.5 mm can with 7.5 mm lead spacing and radial lead mounting for through‑hole PCB use; available in bulk/bag packing for production handling.
• Pb‑free Leadwire / PET Sleeve (series configuration): Series documentation specifies Pb‑free leadwire and Pb‑free PET sleeve configuration for φD sizes 12.5 to 18, applicable to this 16 mm case size.

Typical Applications

• Audio Power Supplies: Bulk energy storage and smoothing in amplifier and preamplifier power rails, leveraging high capacitance and ripple current capability.
• Audio Amplifiers: Local decoupling and transient reservoir for power stages, improving dynamic headroom for demanding music passages.
• Consumer Audio Electronics: Power bus stabilization in active speakers, mixers, and other audio equipment operating within -40°C to 85°C.

Unique Advantages

• Large Energy Storage: 6800 µF at 16 V provides substantial charge reserve for circuits that require sustained current delivery.
• Designed for High Ripple Environments: Specified 2.5 A at 120 Hz and 2.875 A at 10 kHz supports both low‑ and high‑frequency ripple common in audio power domains.
• Durability Under Heat: 2000 hours endurance at 85°C gives designers a quantifiable lifetime metric for thermal reliability planning.
• Wide Operating Temperature: −40°C to 85°C rating enables use across a broad range of ambient conditions encountered in installed audio equipment.
• Compact Radial Form Factor: φ16 × 35.5 mm can with 7.5 mm lead spacing simplifies layout for through‑hole assemblies while conserving board area.
• Series-Level Lead and Sleeve Configuration: Pb‑free leadwire and PET sleeve configuration for 12.5–18 mm case sizes supports lead material considerations in assembly and end‑product compliance planning.
