UPW1C682MHD

The UPW1C682MHD is a miniature, radial‑lead aluminum electrolytic capacitor in Nichicon’s UPW series designed for high‑reliability power applications. It is a polarized, low‑impedance electrolytic capacitor with a rated capacitance of 6.8 mF (6800 µF) at 16 V and a compact φ18 × 35.5 mm can.

Engineered for switching power supplies and automotive electronics, the part delivers high ripple handling, long endurance and wide temperature operation for demanding power‑management and bulk‑smoothing roles.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance at a rated voltage of 16 V with ±20% tolerance.
• Low Impedance — Specified impedance of 30 mΩ to support low‑loss energy transfer in power circuits.
• High Ripple Current — Low‑frequency ripple current 3.128 A at 120 Hz and high‑frequency ripple capability of 3.68 A at 10 kHz, enabling effective smoothing in switching supplies.
• Electrical Losses — Tangent of loss angle (tan δ) 0.26 measured at 20°C, 120 Hz for this capacitance range.
• Durability & Lifetime — Rated endurance of 8000 hours at 105°C, supporting long service life in elevated temperature environments.
• Wide Temperature Range — Operates from −55°C to +105°C to accommodate harsh thermal environments.
• Mechanical & Mounting — Radial lead can package with 7.5 mm lead spacing (±0.5 mm) and φ18 diameter; available in bulk (no terminal forming) or bag packing.
• Automotive‑Grade Qualification — AEC‑Q200 rated for use in applications that require established passive component qualification.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and high ripple current improve regulation and reduce voltage ripple.
• Automotive Power Electronics — Energy storage and decoupling in automotive modules where AEC‑Q200 qualification and 8000 h endurance at 105°C are required.
• DC‑DC Converters and Power Rails — Local bulk capacitance for converters and power rails that benefit from the capacitor’s compact size and high ripple capability.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 3.128 A (120 Hz) and 3.68 A (10 kHz) enable reliable smoothing across a wide frequency range.
• Low series impedance: 30 mΩ impedance reduces losses and supports stable voltage under dynamic load conditions.
• Extended high‑temperature life: 8000 hours at 105°C provides long operational life in elevated temperatures common to power electronics.
• Automotive‑level qualification: AEC‑Q200 rating aligns the part with automotive design and reliability expectations.
• Compact, board‑friendly form: φ18 × 35.5 mm can and radial‑lead mounting with 7.5 mm spacing simplify placement in space‑constrained power modules.
• Production availability: Mass production status and standard packaging options (bulk / bag) support procurement and assembly planning.
