UPW1C681MPD6

The UPW1C681MPD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series, supplied in a radial lead can. It delivers 680 µF capacitance at a 16 V rating with a low loss tangent (tanδ = 0.16 at 20°C, 120 Hz) and low impedance (130 mΩ), targeting compact power designs.

Designed for switching power supplies and automotive electronics, this radial-lead capacitor combines high ripple handling, wide temperature tolerance, and an AEC-Q200 rating to support robust, long-life power filtering in constrained footprints.

Key Features

• Electrical Performance — 680 µF nominal capacitance with ±20% tolerance and 16 V rated voltage; low impedance of 130 mΩ for improved bulk energy delivery and transient response.
• Loss Characteristics — Tangent of loss angle (tanδ) 0.16 measured at 20°C and 120 Hz, enabling predictable AC behavior in filtering applications.
• Ripple and Leakage — Low-frequency ripple current 746.3 mA at 120 Hz and high-frequency ripple current 995 mA at 10 kHz; leakage current specified as 326.4 µA for reliable performance under rated bias.
• Reliability and Endurance — Life/endurance rating of 3000 hours at 105°C; qualified to AEC-Q200 to support demanding environments.
• Mechanical and Packaging — Compact φ8 × 20 mm radial can with 3.5 mm lead spacing (±0.5 mm tolerance); available as bulk (no terminal forming) or bag packing for flexible assembly options.
• Temperature Range and Polarity — Operating temperature range from −55°C to +105°C; polarized capacitor suitable for DC power applications.

Typical Applications

• Switching Power Supplies — Bulk filtering and smoothing in compact switch-mode power supplies, leveraging the low impedance and high ripple-current capability.
• Automotive Electronics — Suited for automotive electronic modules where AEC-Q200 qualification and −55°C to +105°C operation are required.
• Compact Power Modules — Energy storage and decoupling in space-constrained power modules thanks to the φ8 × 20 mm can and radial lead form factor.

Unique Advantages

• High ripple-current capability — Up to 995 mA at 10 kHz and 746.3 mA at 120 Hz to handle switching transients and reduce voltage ripple on DC rails.
• Low impedance — 130 mΩ impedance improves transient response and reduces dissipation in power filtering roles.
• Automotive-grade qualification — AEC-Q200 rating supports use in environments demanding higher reliability and standardized qualification.
• Wide temperature endurance — Rated for −55°C to +105°C with a 3000 h life at 105°C for stable long-term operation under thermal stress.
• Compact radial-can package — φ8 × 20 mm size with 3.5 mm lead spacing simplifies integration into tightly packed PCBs and power assemblies.
