UHE1A682MHD

The UHE1A682MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UHE series designed for high reliability and long life. It provides 6800 µF of capacitance at a 10 V rating in a compact φ16 × 30.5 mm can with 7.5 mm lead spacing.

Built for general-purpose electronics where sustained capacitance, low impedance and extended endurance matter, the part combines low loss characteristics, measurable ripple current handling, and an 8000-hour endurance at 105°C.

Key Features

• High Capacitance: 6800 µF (6.8 mF) nominal capacitance for bulk energy storage and smoothing in compact assemblies.
• 10 V Rated Voltage: Rated for 10 V operation with a capacitance tolerance of -20% to +20%.
• Low Impedance: Specified impedance of 50 mΩ, supporting effective decoupling and stable performance under load.
• Measured Dissipation Factor (tan δ): tanδ = 0.29 measured at 20°C, 120 Hz, 10 V, providing a quantified loss characteristic for design calculations.
• Ripple Current Capability: Low-frequency ripple current 2.76 A at 120 Hz and high-frequency ripple current 3.45 A at 10 kHz, enabling handling of AC ripple across frequencies.
• Leakage Current: Leakage current specified at 680 µA, useful for power-budget and hold-up time planning.
• Long Endurance: Rated life of 8000 hours at 105°C, aligned with UHE series long-life specifications for higher reliability.
• Operating Temperature Range: −40°C to +105°C to support a wide range of ambient conditions.
• Radial Lead, Through-Hole Package: φ16 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm) for straightforward through-hole assembly; available in bulk or bag packing.
• RoHS Compliant: Meets RoHS requirements as indicated in the product data.

Typical Applications

• General-purpose electronic circuits: Provides bulk capacitance and low-impedance filtering where long life and stable performance are required.
• Power supply smoothing: Supports ripple handling and energy storage in power rails within the 10 V rating.
• Through-hole assembly designs: Radial lead form factor and bag/bulk packing for manual or automated through-hole production processes.

Unique Advantages

• High capacitance in a compact footprint: 6800 µF delivered in a φ16 × 30.5 mm can helps reduce board area compared with larger-diameter solutions.
• Quantified ripple capability across frequencies: Separate ripple current specifications for 120 Hz and 10 kHz allow designers to size components for both low- and high-frequency ripple environments.
• Long-term reliability: 8000-hour endurance at 105°C offers predictable performance and lifecycle planning for sustained operation.
• Low impedance and defined loss: 50 mΩ impedance and a measured tanδ provide concrete parameters for thermal and AC loss calculations.
• Wide temperature range: −40°C to +105°C supports diverse operating environments within the part’s ratings.
• Regulatory compliance: RoHS compliance reduces regulatory risk for global product deployments.
