UHW2A680MPD

The UHW2A680MPD is a Nichicon UHW-series miniature aluminum electrolytic capacitor in a radial-lead can. It delivers 68 µF capacitance at a 100 V rating with a compact φ8 × 20 mm case and 3.5 mm lead spacing.

Designed as a high-reliability, high-ripple-current solution for general-purpose electronics, the part combines low impedance at higher frequencies, long endurance (11,000 hours at 105°C), and RoHS compliance for robust power-filtering and decoupling applications.

Key Features

• Electrical Performance — 68 µF capacitance with a rated voltage of 100 V and capacitance tolerance of −20% to +20%.
• Low Dissipation Factor — tanδ of 0.08 (measured at 20°C, 120 Hz), supporting efficient operation with reduced AC loss.
• Low Impedance — specified impedance of 660 mΩ, optimized for improved performance at higher frequencies.
• High Ripple Current Capability — 632 mA at 120 Hz (low frequency) and 1.58 A at 10 kHz (high frequency), enabling handling of significant AC ripple currents.
• Leakage Current — low leakage current of 68 µA when measured under specified conditions.
• Reliability and Endurance — rated life of 11,000 hours at 105°C under rated bias and ripple conditions, with defined limits for capacitance change, tanδ and leakage after endurance testing.
• Mechanical and Mounting — radial lead mounting, φ8 × 20 mm can size, lead spacing 3.5 mm (±0.5 mm), lead diameter suitable for through-hole assembly.
• Packaging and Compliance — available in bulk (no terminal forming) and bag packing; RoHS compliant.

Typical Applications

• General Purpose Power Electronics — 100 V rating and 68 µF capacitance suit common power-supply filtering and decoupling tasks in general-purpose designs.
• High-Ripple Environments — specified ripple currents (632 mA at 120 Hz, 1.58 A at 10 kHz) make it appropriate where elevated AC ripple must be accommodated.
• Compact Through-Hole Designs — φ8 × 20 mm miniature case and radial-lead format enable use in space-constrained, through-hole assemblies.

Unique Advantages

• Miniature footprint with high voltage: φ8 × 20 mm size paired with a 100 V rating provides a compact solution for higher-voltage circuits.
• High ripple-handling capability: Measured ripple currents of 632 mA (120 Hz) and 1.58 A (10 kHz) reduce the need for multiple parallel components in ripple-heavy designs.
• Long endurance at elevated temperature: 11,000-hour life at 105°C supports extended operational lifetimes in thermally demanding applications.
• Low loss at operating frequency: tanδ = 0.08 (20°C, 120 Hz) and 660 mΩ impedance contribute to efficient AC performance.
• Through-hole reliability: Radial lead construction and defined lead spacing (3.5 mm ±0.5 mm) simplify assembly and mechanical retention in PCB designs.
• Regulatory compliance: RoHS compliance supports environmental and materials requirements for modern electronics manufacturing.
