UFW1E682MHD

The UFW1E682MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, designed for audio equipment. It provides high capacitance (6800 µF) at a 25 V rating in a compact radial can package suitable for through-hole mounting.

This part is optimized for audio-related power filtering and decoupling, offering measurable ripple-current capability, controlled loss characteristics, and a 2000-hour endurance at 85°C for sustained performance in commercial audio applications.

Key Features

• Capacitance & Voltage — 6800 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance, providing bulk energy storage for power supply smoothing and decoupling.
• Ripple Current Performance — Rated ripple current of 2.59 A at 120 Hz (low frequency) and 2.9785 A at 10 kHz (high frequency), enabling effective filtering across audio-band and switching noise spectra.
• Loss & Leakage — Dissipation factor (tan δ) of 0.26 measured at 20°C and 120 Hz, and leakage current specified at 5100 µA, giving predictable electrical behavior for design calculations.
• Endurance & Temperature Range — Lifetime rated to 2000 hours at 85°C with an operating temperature range of −40°C to +85°C, supporting continuous operation in typical audio equipment environments.
• Package & Mounting — Radial, can-style package with dimensions φ18 × 35.5 mm (D × L) and 7.5 mm lead spacing; polarized with radial leads for secure through-hole mounting.
• Procurement & Availability — Supplied in bulk (no terminal forming) or bag packing and listed as mass production, simplifying volume procurement and assembly planning.

Typical Applications

• Audio Power Supply Filtering — Bulk capacitance and high ripple-current capability make it suitable for smoothing supply rails in amplifiers and mixers.
• Amplifier Decoupling — Large capacitance supports stable biasing and decoupling in power amplifier stages for reduced ripple and improved audio fidelity.
• Signal Conditioning in Audio Equipment — Useful where reliable energy storage and controlled loss are required for audio signal chains and subsystem power buffering.

Unique Advantages

• High Energy Density: 6800 µF at 25 V provides substantial charge storage in a compact φ18 × 35.5 mm can for efficient board-level energy buffering.
• Broad Ripple-Handling: Specified ripple currents at both 120 Hz and 10 kHz support filtering of low-frequency supply ripple and higher-frequency switching noise common in audio systems.
• Design Predictability: Explicit loss (tan δ) and leakage current figures allow accurate thermal and electrical margining in designs.
• Durability for Continuous Use: 2000-hour endurance at 85°C and −40°C to +85°C operating range help ensure stable performance over product life in commercial audio environments.
• Through-Hole Robustness: Radial lead, polarized can package with 7.5 mm lead spacing facilitates reliable mechanical mounting and straightforward hand or wave-solder assembly.
• Flexible Supply Options: Bulk or bag packing supports both OEM production and smaller-scale assembly needs.
