UHW0J682MHD

The UHW0J682MHD is a miniature, high-reliability aluminum electrolytic capacitor in the Nichicon UHW series, delivered in a radial-lead can. It provides 6800 µF (6.8 mF) capacitance at a 6.3 V rating with a compact φ12.5×30.5 mm case and 5 mm lead spacing.

Designed for general-purpose electronic power applications, this part offers low impedance and high ripple-current capability across a wide temperature range (−40 °C to 105 °C) with a rated endurance of 10,000 hours at 105 °C.

Key Features

• Capacitance & Voltage: 6.8 mF capacitance at a rated voltage of 6.3 V, with capacitance tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance Performance: Rated impedance of 33 mΩ supports lower AC voltage drop and improved dynamic response; datasheet notes lower impedance at high frequency range for the UHW series.
• High Ripple Current Capability: Low-frequency ripple current 3.226 A (120 Hz) and high-frequency ripple current 3.795 A (10 kHz), enabling sustained ripple handling in compact designs.
• Leakage & Loss Characteristics: Specified leakage current 428.4 μA and tangent of loss angle tanδ = 0.31 (measured at 20 °C, 120 Hz) for defined dissipation and standby behavior.
• Reliability & Endurance: Endurance rated 10,000 hours at 105 °C under DC bias plus rated ripple current, with stability limits defined for capacitance, tanδ, and leakage after testing.
• Mechanical & Mounting: Radial lead mounting, case size φ12.5×30.5 mm, lead spacing 5 mm (±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• Environmental Compliance: RoHS compliant as indicated for the UHW series.

Typical Applications

• General Purpose Electronics: Use where a compact, high-capacitance radial-lead capacitor is required for bulk storage or decoupling in general-purpose boards and assemblies.
• Power Supply Filtering: Suitable for applications that benefit from high ripple-current handling and low impedance at both low and high frequencies.
• Embedded and Industrial Equipment: Appropriate for designs that require extended endurance at elevated temperature (10,000 hours at 105 °C) and robust performance across −40 °C to 105 °C.

Unique Advantages

• High Capacitance in a Small Footprint: 6.8 mF in a φ12.5×30.5 mm can reduces board area for bulk energy storage compared with larger packages.
• Defined High-Frequency Performance: Lower impedance at high frequency for improved ripple attenuation and transient support in switching environments.
• Strong Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz enable reliable operation under continuous AC loading conditions.
• Long-Term Thermal Endurance: 10,000-hour rating at 105 °C provides predictable lifetime behavior for long-running equipment.
• Radial-Lead Convenience: Standard radial-lead form factor and 5 mm lead spacing simplify through-hole assembly and replacement processes.
• Regulatory Compliance: RoHS status supports use in assemblies requiring restricted substance compliance.
