LNT2A683MSEB

The LNT2A683MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series. It provides 68 mF (68,000 µF) capacitance at a 100 V rating in a radial can with screw terminals, designed for general-purpose power applications.

Key attributes include high ripple-current capability, a wide operating temperature range from −40 °C to +105 °C, and a rated endurance of 2,000 hours at 105 °C—making it suitable where substantial bulk capacitance and robust thermal performance are required.

Key Features

• High Capacitance: 68 mF (68,000 µF) nominal capacitance with tolerance of −20% to +20%, providing substantial energy storage in a single component.
• 100 V Rated Voltage: Rated for 100 V operation, suitable for higher-voltage DC systems within the LNT series range.
• Screw-Terminal, Radial Can Package: Screw terminal mounting for secure electrical and mechanical connection; package form described as radial, can − screw terminals with physical size φ90 × 170L (approx. L: 17 cm × D: 9 cm).
• High Ripple Current Handling: Low-frequency ripple current 18.2 A at 120 Hz and high-frequency ripple current 20.93 A at 100 kHz, enabling effective smoothing under significant AC ripple conditions.
• Thermal and Endurance Ratings: Operating temperature −40 °C to +105 °C with endurance specified at 2,000 hours at 105 °C under rated ripple and DC bias.
• Electrical Loss and Leakage: Dissipation factor (tan δ) of 0.3 measured at 20 °C and 120 Hz; leakage current listed as 5,000 µA.
• Compliance and Packaging: RoHS compliant and supplied in cardboard packing; product status: mass production.

Typical Applications

• General-purpose power modules — Designed for systems that require a high-capacitance, screw-terminal electrolytic capacitor with a 100 V rating and robust temperature performance.
• Bulk energy storage and smoothing — Provides large capacitance for energy buffering in designs that need significant charge storage and ripple-current capability.
• Industrial and commercial equipment — Applicable where long endurance at elevated temperature (2,000 h at 105 °C) and secure screw-terminal connections are important.

Unique Advantages

• Substantial single-component capacitance: 68 mF reduces the need for multiple lower-value capacitors, simplifying BOM and PCB real estate for bulk storage requirements.
• High ripple-current capability: 18.2 A (120 Hz) and 20.93 A (100 kHz) ratings support demanding ripple conditions without overspecifying parallel components.
• Wide operating temperature range: −40 °C to +105 °C accommodates applications exposed to broad thermal environments while maintaining performance.
• Durable screw-terminal mounting: Robust mechanical and electrical connection suitable for systems requiring secure, high-current terminations.
• Verified endurance at elevated temperature: 2,000-hour life at 105 °C under rated conditions provides predictable long-term behavior for design planning.
• Regulatory compliance: RoHS compliant to support environmental and supply-chain requirements.
