UPW1E682MHD

The UPW1E682MHD is a miniature, low-impedance aluminum electrolytic capacitor in Nichicon’s UPW series, specified for high-reliability power applications. It is a radial-lead, polarized can-type capacitor with a rated capacitance of 6.8 mF (6800 μF) at 25 V and is designed for applications that require high ripple handling and long endurance.

This part targets switching power supplies and other power-management circuits—particularly where compact size, high ripple current capability, and extended lifetime at elevated temperature are required.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 μF) nominal capacitance with a rated voltage of 25 V and capacitance tolerance of ±20% (−20% to 20%).
• Low impedance — Specified impedance of 28 mΩ, supporting efficient filtering and decoupling in power stages.
• High ripple current capability — Low-frequency ripple current 3.23 A (at 120 Hz) and high-frequency ripple current 3.8 A (at 10 kHz), enabling robust smoothing in both line-frequency and switching environments.
• Loss characteristics — Tangent of loss angle (tan δ) of 0.24 measured at 20°C, 120 Hz for this part.
• Thermal & endurance profile — Operating temperature range from −55°C to +105°C with rated endurance of 8000 hours at 105°C.
• Mechanical and packaging — Compact can: φ18 × 40 mm length; radial lead mounting with 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Leakage current — Specified leakage current of 5100 μA after standard voltage application.
• AEC-Q200 rated — Built to an AEC-Q200 rating for enhanced reliability in demanding environments.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where high ripple currents and low impedance are required for stable voltage regulation.
• Automotive Electronics — Power-conditioning and energy storage in automotive modules that benefit from AEC-Q200 qualification and extended high-temperature endurance.
• Industrial Power Systems — Decoupling and buffering in industrial converters and power-management subsystems operating across a wide temperature range.

Unique Advantages

• High capacitance in a miniature package — 6800 μF in a φ18 × 40 mm can provides substantial energy storage while keeping board space compact.
• Strong ripple-handling capability — Specified ripple currents at both low and high frequencies support mixed-frequency power environments and reduce thermal stress on the capacitor.
• Low impedance for efficient filtering — 28 mΩ impedance helps minimize voltage ripple and improves transient response in power rails.
• Long life at elevated temperature — 8000 hours at 105°C supports designs that require extended lifetime under continuous thermal stress.
• AEC-Q200 qualification — Provides an added level of reliability assurance for demanding applications where component stress and qualification matter.
• Radial-lead form factor — Easy-to-mount radial can with defined lead spacing simplifies through-hole assembly and mechanical retention.
