UPW0J682MHD

The UPW0J682MHD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon's UPW series designed for low impedance and high reliability. It delivers 6800 µF at 6.3 V in a compact φ16 × 25 mm can, optimized for power‑handling roles such as switching power supplies and other power‑filtering applications.

Built for extended operation across a wide temperature range (−55 °C to 105 °C) and qualified to AEC‑Q200, this part provides high ripple current capacity and long endurance for demanding electronic designs.

Key Features

• Capacitance & Tolerance: 6800 µF (6.8 mF) with ±20% tolerance (120 Hz, 20 °C), suitable for bulk energy storage and smoothing of DC rails.
• Rated Voltage: 6.3 V DC rating for low‑voltage power systems.
• Low Impedance: 44 mΩ impedance, reducing ripple voltage and improving transient response in power circuits.
• High Ripple Current Capability: 2.176 A at 120 Hz (low frequency) and 2.56 A at 10 kHz (high frequency), enabling reliable operation under heavy AC ripple conditions.
• Loss Tangent (tan δ): 0.32 measured at 20 °C, 120 Hz, indicating characteristic dissipation for this capacitance and voltage.
• Long Endurance: Rated for 8000 hours at 105 °C under specified conditions, supporting long life in elevated temperature environments.
• Wide Operating Temperature: −55 °C to 105 °C for use across harsh ambient ranges.
• Radial Lead, Compact Package: φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm), offered as bulk (no terminal forming) or bag packing for flexible assembly.
• Automotive‑grade Qualification: AEC‑Q200 rating, suitable for designs requiring that level of component qualification.
• Safety Feature: Radial lead construction includes a pressure relief vent as specified for the series.

Typical Applications

• Switching Power Supplies: Bulk capacitors and output filtering where low impedance and high ripple current capability improve regulation and transient response.
• Automotive Electronics: Power smoothing and energy storage in modules that require AEC‑Q200 qualified components and wide temperature operation.
• DC Rail Stabilization: Local energy reservoir for low‑voltage DC rails to reduce voltage sag during load transients.

Unique Advantages

• Compact energy density: 6800 µF in a φ16 × 25 mm can saves PCB area while providing large bulk capacitance for power systems.
• High ripple handling: Specified ripple currents at both low and high frequencies support robust performance in switching environments.
• Low impedance: 44 mΩ impedance lowers AC voltage drop and improves converter stability.
• Long thermal endurance: 8000 hours at 105 °C provides predictable long‑term behavior in high‑temperature applications.
• Automotive qualification: AEC‑Q200 rating supports designs targeting automotive and other demanding markets that require component qualification.
• Flexible packaging: Available in bulk (no terminal forming) or bag packing to match production handling and assembly processes.
