UPW2A680MPD

The UPW2A680MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series, supplied in a radial-lead can. Designed for low impedance and compact power designs, it targets switching power supplies and other power-conditioning circuits where long endurance and stable performance are required.

Key characteristics include a 68 µF capacitance at 100 V rating, a wide operating temperature range from −55°C to 105°C, and a 5000-hour endurance rating at 105°C—making it suitable for demanding environments that require sustained ripple handling and thermal stability.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 100 V rated voltage and tolerance of −20% to +20%.
• Low Loss and Impedance — Specified tanδ of 0.08 (measured at 20°C, 120 Hz, 100 V) and an impedance of 600 mΩ for improved AC performance and filtering.
• Ripple Current Capability — Low-frequency ripple current of 318.5 mA at 120 Hz and high-frequency ripple current of 490 mA at 10 kHz to support effective smoothing in switching applications.
• Leakage Current — Specified leakage current of 204 µA, measured under rated conditions to ensure predictable power loss and startup behaviour.
• High Temperature Endurance — Rated for 5000 hours at 105°C, enabling long-term operation under elevated temperature stress.
• Robust Temperature Range — Operates from −55°C to 105°C for use across a broad set of environmental conditions.
• Compact Radial Package — 10 mm diameter × 20 mm length can with 5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for manual or automated assembly flows.
• AEC‑Q200 Qualified — Meets AEC‑Q200 reliability requirements for designs that require that qualification.

Typical Applications

• Switching Power Supplies — Provides low-impedance bulk capacitance and ripple handling for output filtering and energy storage in compact switch-mode supplies.
• Automotive Electronics — AEC‑Q200 qualification and a wide temperature range make it suitable for automotive control modules and in-vehicle power conditioning.
• Power Filtering and Decoupling — Compact form factor and defined ripple current ratings enable reliable smoothing and decoupling in power management circuits.

Unique Advantages

• Miniature, space-saving form — φ10 × 20 mm can provides substantial capacitance in a small footprint for dense board layouts.
• Predictable AC performance — Low tanδ and defined impedance support stable filtering behavior under AC conditions.
• Designed for elevated temperatures — 5000-hour endurance at 105°C reduces the need for frequent replacement in hot environments.
• Clarified ripple handling — Separate low-frequency and high-frequency ripple current specifications (318.5 mA @120 Hz, 490 mA @10 kHz) help match the component to the target switching spectrum.
• Automotive-grade reliability — AEC‑Q200 rating enables inclusion in designs that require that level of component qualification.
• Controlled leakage — Specified leakage current (204 µA) for predictable system standby and bias behaviors.
