UHV1A682MHD

The UHV1A682MHD is a Nichicon UHV series aluminum electrolytic capacitor in a radial-lead can, offering 6800 µF capacitance at a 10 V rating. It targets general-purpose electronic designs that require large bulk capacitance, low impedance, and high ripple-handling in a compact φ16 × 25 mm package.

Designed for continuous operation across –40°C to 105°C with a rated endurance of 6000 hours at 105°C, this part delivers measurable ripple current capability and controlled leakage for robust power filtering and energy-storage tasks.

Key Features

• Capacitance & tolerance — 6800 µF nominal with tolerance of −20% to +20%, providing substantial bulk storage for low-voltage systems.
• Rated voltage & polarization — 10 V rated, polarized electrolytic design suitable for DC applications requiring high capacitance.
• Low impedance — Specified impedance of 33 mΩ, reducing AC voltage drop under ripple and transient loads.
• High ripple current capability — Low-frequency ripple current 3.392 A at 120 Hz and high-frequency ripple current 3.99 A at 100 kHz, enabling effective handling of both low- and high-frequency ripple components.
• Thermal endurance — Rated life of 6000 hours at 105°C, supporting long-term operation at elevated temperatures.
• Leakage and dissipation — Leakage current 680 µA; measured tanδ (DF) 0.28 at 20°C, 120 Hz, 10 V for loss characterization.
• Package & mounting — Radial lead can, size φ16 × 25 mm, lead spacing 7.5 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for flexible assembly options.
• Environmental compliance — RoHS compliant.

Typical Applications

• General-purpose power electronics — Bulk energy storage and smoothing where 6800 µF at 10 V and high ripple capability reduce voltage variation under load.
• Power supply filtering — Use in DC filtering stages to handle combined low- and high-frequency ripple up to the specified ripple current limits.
• DC link and decoupling — Local energy reservoir for low-voltage DC systems requiring low impedance (33 mΩ) to minimize ripple-induced losses.

Unique Advantages

• High ripple tolerance: Rated for 3.392 A at 120 Hz and 3.99 A at 100 kHz to support demanding ripple environments without excessive heating.
• Low impedance: 33 mΩ impedance helps reduce AC voltage drop and improves dynamic response in power circuits.
• Compact radial can: φ16 × 25 mm dimensions and 7.5 mm lead spacing deliver large capacitance in a small footprint for space-constrained boards.
• Long-term thermal reliability: 6000-hour endurance at 105°C for sustained performance in elevated-temperature applications.
• Measured loss and leakage data: Specified tanδ and leakage current values allow predictable AC loss and standby behavior in design margins.
• RoHS compliant supply: Environmentally compliant construction for modern manufacturing requirements.
