UHE0J682MHD3

The UHE0J682MHD3 is a radial lead aluminum electrolytic capacitor from Nichicon’s UHE series, providing 6.8 mF (6800 µF) nominal capacitance at a 6.3 V rating. It is a compact, polarized can-style capacitor designed for general-purpose applications that require high capacitance in a small radial package.

This part combines low impedance, defined ripple-current capability at both low and high frequencies, and long-endurance performance rated to 8000 hours at 105°C for 6.3 V units, making it suitable where sustained thermal and electrical stress are expected.

Key Features

• Capacitance & Voltage — Nominal 6.8 mF (6800 µF) capacitance with a rated voltage of 6.3 V and capacitance tolerance of -20% to +20%.
• Low Impedance and Loss — Impedance of 67 mΩ and a tangent of loss angle (tan δ) of 0.32 (measured at 20°C, 120 Hz), supporting efficient charge/discharge behavior in the intended frequency band.
• Ripple Current Capability — Rated low-frequency ripple current of 2.288 A at 120 Hz and high-frequency ripple current of 2.86 A at 10 kHz, specified for robustness under AC stress.
• Leakage Current — Specified leakage current of 428.4 µA, in line with the product’s electrical characterization.
• Long Endurance — Endurance rating of 8000 hours at 105°C for 6.3 V units, allowing extended operation under elevated temperature conditions.
• Operating Temperature Range — Specified for -40°C to +105°C to accommodate a wide range of thermal environments.
• Compact Radial Package — φ18 × 20 mm can with 7.5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole PCB implementation.
• Packaging & Availability — Supplied in bulk (no terminal forming) / bag packing and listed as mass production; RoHS compliant.

Typical Applications

• General-purpose electronics — Suited for general-purpose circuits where a polarized aluminum electrolytic capacitor with 6.8 mF at 6.3 V is required.
• General-purpose electronics — Applicable in designs that require defined ripple-current handling and long endurance at up to 105°C.
• General-purpose electronics — Used in through-hole, radial-lead implementations where compact high-capacitance components are needed.

Unique Advantages

• High-capacitance in a compact package — 6.8 mF nominal capacitance in a φ18 × 20 mm can provides significant bulk capacitance for space-constrained through-hole designs.
• Measured low impedance — 67 mΩ impedance and a specified tan δ value provide predictable AC performance at typical measurement conditions (20°C, 120 Hz).
• Defined ripple-current ratings — Separate low-frequency and high-frequency ripple-current specifications (2.288 A at 120 Hz and 2.86 A at 10 kHz) clarify thermal and electrical handling across common ripple bands.
• Proven long-life rating — 8000 hours endurance at 105°C for 6.3 V units supports longer service intervals in thermally demanding applications.
• Robust temperature range — Operation from -40°C to +105°C covers a broad set of environmental conditions for general-purpose electronics.
• Production-ready packaging — Available in bulk/bag packing and listed as mass production, simplifying procurement and assembly planning.
