UPW1A682MHD6

The UPW1A682MHD6 is a radial‑lead, miniature aluminum electrolytic capacitor from Nichicon's UPW series, offering 6800 µF capacitance at a 10 V rating. Designed for low impedance and high reliability in compact power designs, it delivers sustained performance across a wide temperature range for demanding applications.

Key attributes include low ESR (40 mΩ), high ripple handling (2.329 A at 120 Hz; 2.74 A at 10 kHz), long endurance (8,000 hours at 105°C), and AEC‑Q200 qualification for demanding environments.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) nominal capacitance rated for 10 V DC, suitable for bulk energy storage and smoothing in power rails.
• Low Impedance: Specified impedance of 40 mΩ helps reduce voltage ripple and improve transient response in switching power supplies.
• High Ripple Current Capability: Low‑frequency ripple current 2.329 A at 120 Hz and high‑frequency ripple current 2.74 A at 10 kHz; frequency coefficient for 1,200–15,000 µF applies (0.85 at 120 Hz, 1.00 at 10 kHz).
• Reliability & Endurance: Life rating of 8,000 hours at 105°C under rated conditions, with specified capacitance and tan δ stability after endurance testing.
• Wide Operating Temperature: Rated from −55°C to +105°C for operation across harsh thermal environments.
• Electrical Losses: tan δ (DF) = 0.19 measured at 20°C, 120 Hz for the 10 V rating, enabling predictable dissipation characteristics.
• Package & Mounting: Radial lead, can package with φ18 × 25 mm dimensions, lead spacing 7.5 mm (±0.5 mm), and available in bulk or bag packing.
• Qualification: AEC‑Q200 rated for use in applications requiring component qualification to automotive passive component standards.

Typical Applications

• Switching Power Supplies: Bulk output smoothing and decoupling where low ESR and high ripple current capacity reduce voltage ripple and improve regulator stability.
• Automotive Electronics: Power filtering and energy storage in vehicle systems that require AEC‑Q200 qualified components and wide operating temperature range.
• Industrial Power Modules: Energy buffering and ripple attenuation in industrial converters and motor drive power stages operating across −55°C to +105°C.

Unique Advantages

• High Ripple Tolerance: Rated ripple currents at both low and high frequency mean the capacitor can handle diverse switching environments without performance degradation.
• Compact, High‑Capacitance Package: 6800 µF in a φ18 × 25 mm can reduces board area compared with multiple smaller devices, simplifying layout for bulk storage.
• Long Endurance at Elevated Temperature: 8,000 hours at 105°C provides predictable lifecycle performance for designs requiring long‑term stability.
• Low ESR for Improved Efficiency: 40 mΩ impedance helps minimize power loss and thermal rise in high‑current applications.
• Automotive‑Grade Qualification: AEC‑Q200 rating supports use in applications with formal component qualification requirements.
• Straightforward Through‑Hole Mounting: Radial lead form and standard 7.5 mm lead spacing facilitate easy placement and soldering in through‑hole assemblies.
