UHW0J682MHD6

The UHW0J682MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series, optimized for high ripple current and lower impedance at higher frequencies. With a capacitance of 6,800 µF (6.8 mF) at a rated voltage of 6.3 V, it is designed for general-purpose electronic applications requiring bulk capacitance in a compact can.

This component combines high ripple-handling capability, long endurance, and a wide operating temperature range (−40 °C to +105 °C), making it suitable for designs where sustained performance and reliability are required over extended operational lifetimes.

Key Features

• Capacitance and Voltage — 6,800 µF (6.8 mF) nominal capacitance with a rated voltage of 6.3 V; capacitance tolerance −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 3.039 A (120 Hz) and high-frequency ripple current of 3.575 A (10 kHz), suitable for applications with significant AC ripple demands.
• Low Impedance — Rated impedance of 45 mΩ supports effective high-frequency performance and energy smoothing in compact layouts.
• Leakage and Loss Characteristics — Specified leakage current of 428.4 µA and tangent of loss angle (tan δ) of 0.31 (20 °C, 120 Hz).
• Long Endurance — Rated lifetime of 10,000 hours at 105 °C under specified conditions, with stable capacitance and leakage performance after endurance testing.
• Mechanical and Mounting — Radial lead (can) package, size φ16 × 20L mm, lead spacing 7.5 mm (±0.5 mm); offered in bulk (no terminal forming) or bag packing.
• Temperature Range and Compliance — Operating temperature −40 °C to +105 °C; RoHS compliant.

Typical Applications

• General-Purpose Power Filtering — Bulk smoothing and ripple suppression in electronic equipment where robust ripple handling and low impedance are required.
• DC Link and Energy Storage — Local energy buffering in compact power subsystems that must deliver repeated ripple currents over long service life.
• High-Ripple Environments — Circuits that experience significant AC ripple at both low and high frequencies benefit from the part’s specified ripple current performance.

Unique Advantages

• High ripple capacity in a compact can — Delivers over 3 A ripple handling while occupying a φ16 × 20 mm footprint, enabling compact board designs without sacrificing ripple tolerance.
• Low impedance for improved high-frequency performance — 45 mΩ impedance helps reduce voltage excursion under dynamic loads and supports better filtering at higher frequencies.
• Extended endurance at elevated temperature — 10,000-hour rating at 105 °C provides predictable long-term behavior in demanding thermal environments.
• Clear electrical specifications for design predictability — Defined tan δ, leakage, and frequency-related ripple values allow engineers to model performance precisely in power and smoothing applications.
• RoHS compliant — Conforms to applicable RoHS directives for equipment requiring restricted substance compliance.
