UPW0J681MPD

The UPW0J681MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series, configured as a radial-lead polarized can. It delivers 680 µF at 6.3 V with low impedance and engineered endurance for demanding power applications.

Designed for switching power supplies and electronic power regulation, this part targets applications that require compact bulk capacitance, elevated ripple handling, and operation across a wide temperature range from −55°C to 105°C. It carries an AEC-Q200 rating and is available in mass-production quantities.

Key Features

• Capacitance and Voltage: 680 µF nominal capacitance at a rated voltage of 6.3 V with tolerance −20% to +20%.
• Low Impedance: Measured impedance of 180 mΩ to support stable DC bus filtering and transient suppression in compact power stages.
• High Ripple Capability: Low-frequency ripple current 566.3 mA at 120 Hz and high-frequency ripple current 755 mA at 10 kHz, enabling effective smoothing in both mains‑frequency and switching environments.
• Reliability & Endurance: Rated lifetime of 5000 hours at 105°C; endurance performance follows the UPW series specification for capacitance and tan δ after long-term bias and ripple exposure.
• Temperature Range: Operates from −55°C to 105°C, supporting a broad range of thermal environments.
• Compact Radial Package: Metal-can radial lead construction, size φ10 × 12.5 mm (D × L), lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Electrical Loss Characteristic: tan δ (DF) of 0.22 measured at 20°C, 120 Hz, for the 6.3 V rating.
• Leakage Current: Specified leakage current of 128.52 µA under rated conditions.

Typical Applications

• Switching Power Supplies: Bulk and output filtering where low impedance and high ripple capability help maintain stable voltages under switching transients.
• DC–DC Converters: Local energy storage and decoupling in compact converters; the 680 µF capacitance and radial package enable dense board-level designs.
• Automotive Electronics: Suitable for automotive systems that require AEC-Q200 qualification and wide temperature operation, including body electronics and power modules.
• Industrial Power Regulation: Filtering and smoothing in industrial control and embedded power systems requiring extended high-temperature endurance.

Unique Advantages

• High Bulk Capacitance in a Small Footprint: 680 µF in a φ10 × 12.5 mm can reduces board area while providing substantial energy storage.
• Low-Impedance Performance: 180 mΩ impedance helps minimize voltage drop and improves transient response in power rails.
• Robust Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz allow reliable operation across mains and switching frequencies.
• Designed for Harsh Environments: −55°C to 105°C operating range and 5000-hour endurance at 105°C support long-term stability under thermal stress.
• AEC-Q200 Rated: Offers a recognized reliability benchmark for applications requiring electronics-grade qualification.
• Through-Hole Simplicity: Radial-lead can with 5 mm lead spacing simplifies PCB mounting and mechanical retention for power assemblies.
