UFW0J682MHD

The UFW0J682MHD is a Nichicon UFW-series radial-lead aluminum electrolytic capacitor specified for audio applications. It delivers high bulk capacitance (6,800 µF) in a compact φ12.5 × 25 mm radial can, offering a combination of capacitance density, ripple-current capability, and a wide operating temperature range suitable for audio electronics.

Key value propositions include substantial low- and high-frequency ripple-current handling, a defined 2,000-hour endurance at 85°C, and a polarized radial-lead package for conventional through-hole audio assemblies. Note: this part is listed as End Of Life.

Key Features

• High Bulk Capacitance — 6.8 mF (6,800 µF) provides substantial energy storage for power supply smoothing and bulk decoupling.
• Voltage Rating — Rated at 6.3 V to match low-voltage audio power rails and low-voltage supply designs.
• Ripple Current Handling — 1,600 mA at 120 Hz (low frequency) and 1,840 mA at 10 kHz (high frequency) for both mains-frequency and higher-frequency ripple management.
• Reliability & Lifetime — Rated endurance of 2,000 hours at 85°C, with an operating temperature range of −40°C to +85°C for typical audio-environment conditions.
• Electrical Characteristics — Polarized capacitor with ±20% capacitance tolerance and a measured tan δ of 0.38; specified leakage current of 1,285.2 µA.
• Radial Through-Hole Package — φ12.5 × 25 mm can, 5 mm lead spacing, 0.6 mm lead diameter (series typical), suited for conventional PCB mounting and retrofit replacements.
• Packaging — Supplied in bulk/bag packing for volume assembly or service stock.

Typical Applications

• Audio equipment — Bulk energy storage and smoothing in audio power supplies where high capacitance and ripple handling are required.
• Audio signal electronics — Use where polarized aluminum electrolytic capacitance is needed for decoupling and coupling in through-hole designs.
• Repair and maintenance — Replacement component for legacy or service applications matching φ12.5 × 25 mm radial can dimensions and 6.3 V rating.

Unique Advantages

• Large capacitance in a compact footprint — 6,800 µF in a φ12.5 × 25 mm can reduces board area for through-hole bulk capacitance needs.
• Dual-frequency ripple capability — Specified ripple current at both 120 Hz and 10 kHz supports performance across low and high ripple-frequency conditions.
• Designed for audio use — Part of Nichicon’s UFW series, intended for audio equipment applications, aligning electrical characteristics with audio power requirements.
• Wide temperature operation — −40°C to +85°C rating supports a broad range of operating environments common to consumer and pro-audio gear.
• Through-hole ease-of-use — Radial lead package and standard lead spacing simplify PCB layout and field replacement.
• Defined endurance — 2,000 hours at 85°C provides an explicit reliability expectation for design-in and service planning.

Why Choose UFW0J682MHD?

UFW0J682MHD offers a straightforward, specification-driven choice when you need substantial bulk capacitance, clear ripple-current ratings at both low and high frequencies, and a compact radial-can package compatible with through-hole assembly. As a Nichicon UFW-series component specified for audio equipment, it provides engineers a predictable electrical profile—capacitance, tolerance, leakage, tan δ, and endurance—useful for design, repair, and replacement scenarios.

This part is suitable for designers and technicians focused on audio electronics who require verified ripple handling and a defined thermal-endurance rating. Because the unit is listed End Of Life, it is especially relevant for maintenance, service stock, and controlled-production scenarios where matching an existing specification is required.
