LNT2G682MSEJ

The LNT2G682MSEJ is a screw-terminal, radial can aluminum electrolytic capacitor designed for general-purpose power system applications. It provides 6.8 mF capacitance at a 400 V rating in a robust φ90 × 150 mm (D × L) package with screw terminals for secure electrical and mechanical connections.

Key value comes from its combination of high capacitance and high-voltage rating, high ripple-current capability at both low and high frequencies, and a long rated endurance of 5,000 hours at 105°C—making it suitable where sustained filtering, bulk energy storage, or smoothing are required within the stated temperature range.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a rated voltage of 400 V and tolerance of -20% to +20%.
• Screw-Terminal Radial Can — Robust radial can package with screw terminals for reliable electrical connection and secure mounting in larger power assemblies.
• High Ripple Current Capability — Rated low-frequency ripple current of 26.9 A at 120 Hz and high-frequency ripple current of 37.66 A at 100 kHz, supporting demanding ripple conditions.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) specified at 0.2 (measured at 20°C, 120 Hz) and leakage current listed as 4940 µA.
• Thermal Endurance — Rated operating temperature range of -25°C to +105°C with a specified life of 5,000 hours at 105°C under rated ripple and DC bias.
• Packaging & Production — Supplied in cardboard packing and currently in mass production; RoHS compliant.

Typical Applications

• General-purpose power systems — For designs that require 6.8 mF at 400 V in a screw-terminal radial can for bulk energy storage and smoothing.
• High-voltage filter circuits — Used where sustained performance at 400 V and elevated ripple currents is needed within the -25°C to +105°C range.
• Industrial power assemblies — Suited to larger power modules or assemblies needing a secure screw-terminal capacitor with long endurance at 105°C.

Unique Advantages

• High energy storage in a compact can — 6.8 mF capacitance at 400 V provides substantial bulk capacitance for high-voltage systems.
• Sustained ripple handling — Explicit low- and high-frequency ripple current ratings (26.9 A at 120 Hz; 37.66 A at 100 kHz) support designs with significant AC stress.
• Long rated life at elevated temperature — 5,000 hours endurance at 105°C under rated conditions gives predictable performance over extended operation.
• Secure screw-terminal mounting — Radial can with screw terminals simplifies installation and provides mechanically robust connections for heavier current paths.
• Measured electrical characteristics — Specified tan δ (0.2 at 20°C, 120 Hz) and documented leakage current allow straightforward electrical margining and reliability planning.
• Compliant supply chain — RoHS-compliant and supplied in cardboard packing for standard handling and storage.
