LNK2H682MSEJBN

The LNK2H682MSEJBN from Nichicon is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 6.8 mF (6800 µF) at a 500 V rating in a radial can with screw terminals, providing high capacitance and high voltage capability in a compact, serviceable package.

Engineered for sustained operation up to 85°C with a 5000‑hour load life and specified low‑ and high‑frequency ripple current ratings, this capacitor is suited to applications that require bulk energy storage, ripple handling, and robust long‑term performance.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a 500 V rated voltage, suitable for high‑voltage DC applications.
• Ripple Current Handling — Rated ripple current of 21.2 A at 120 Hz (low frequency) and 29.68 A at 10 kHz (high frequency), supporting effective ripple filtering and energy buffering.
• Endurance & Temperature — Rated for 5000 hours at 85°C; operating temperature range −25°C to +85°C for stable performance across common industrial environments.
• Leakage & Reliability — Leakage current specified at 5000 µA; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket as per series specifications.
• Construction & Mounting — Radial can with screw terminal mounting and φ90 × 170L size, offering secure mechanical connection and straightforward serviceability.
• Safety & Voltage Proof — Meets voltage‑proof requirement of AC 2500 V for 1 minute between terminal and bracket per series specifications.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply bulk storage — High capacitance and 500 V rating provide bulk energy storage for regulated DC supplies and power conversion stages.
• Ripple filtering — High low‑ and high‑frequency ripple current ratings enable effective smoothing of AC‑to‑DC and switching regulator outputs.
• Industrial power electronics — Long life at 85°C and robust insulation characteristics suit general‑purpose industrial equipment requiring durable energy storage.

Unique Advantages

• High voltage capability: 500 V rating allows use in higher‑voltage DC systems without series stacking.
• Large stored energy: 6.8 mF capacitance provides significant bulk storage for load transients and hold‑up time improvements.
• Broad ripple tolerance: Specified ripple currents at both 120 Hz and 10 kHz support performance across low and high switching frequencies.
• Durable under elevated temperature: 5000 h life at 85°C offers predictable longevity in warm operating environments.
• Secure mechanical mounting: Screw terminal design simplifies installation and replacement in bench‑serviceable power systems.
• Compliance: RoHS status affirms adherence to environmental restrictions included in the product data.
