UVK1A682MHD

The UVK1A682MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVK series, offering high capacitance in a compact, miniature-sized can (φ16 × 25 mm). Designed for general-purpose electronic designs, it delivers bulk energy storage and filtering capability where a low-voltage, high-capacitance solution is required.

Key value comes from its 6800 µF capacitance at 10 V, substantial ripple-current handling at both low and high frequencies, and a 2000-hour endurance rating at 85°C—making it suitable for robust power-conditioning roles in industrial and electronic equipment.

Key Features

• Capacitance & Voltage: 6800 µF nominal capacitance with a rated voltage of 10 V and a tolerance of ±20% (120 Hz, 20°C).
• Ripple Current Performance: Low-frequency ripple current of 2.25 A at 120 Hz and high-frequency ripple current of 2.587 A at 10 kHz to support power filtering and smoothing tasks.
• Endurance & Temperature Range: Rated for 2000 hours at 85°C and an operating temperature range of −40°C to +85°C.
• Leakage Current: Specified leakage current of 2040 µA after application of rated voltage.
• Compact Radial Package: Miniature φ16 × 25 mm can with radial leads (lead spacing 7.5 mm ±0.5 mm) for through-hole mounting and straightforward PCB layout.
• Polarized Construction: Polarized aluminum electrolytic design for bulk energy storage and decoupling applications.
• Packaging & Availability: Available in bulk (no terminal forming) or bag packing and currently in mass production.
• Regulatory: UVK series is compliant to the RoHS directive.

Typical Applications

• Power-supply smoothing: High capacitance (6800 µF) and substantial ripple-current ratings make this part well-suited for smoothing DC rails and reducing ripple in low-voltage power supplies.
• DC/DC converter input/output filtering: The combination of large capacitance and both low- and high-frequency ripple handling supports input and output decoupling in converter modules.
• Energy hold-up and local bulk storage: Compact φ16 × 25 mm footprint provides local energy storage for transient demands in industrial and electronic systems.

Unique Advantages

• High bulk capacitance in a small can: 6800 µF in a φ16 × 25 mm package reduces board area compared with larger cans while delivering necessary energy storage.
• Dual-frequency ripple capability: Rated ripple currents at 120 Hz and 10 kHz address both mains-related and switching-frequency ripple, aiding stable power conditioning.
• Robust thermal endurance: 2000 hours at 85°C provides predictable long-term performance in elevated-temperature environments.
• Clear mechanical footprint: Standard radial lead spacing (7.5 mm ±0.5 mm) simplifies PCB layout and assembly planning.
• Practical packing options: Bulk and bag packing choices support both high-volume manufacturing and smaller-scale assembly needs.
