LNT1K683MSE

The LNT1K683MSE from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series, rated 80 V with 68,000 µF (68 mF) capacitance and ±20% tolerance. It is a radial can, screw-terminal package (φ90 × 140L) designed for general-purpose high-capacitance, high-voltage applications.

Key value propositions include a wide operating temperature range of −40°C to +105°C, 2000 hours of rated lifetime at 105°C, and robust screw-terminal mounting suitable for systems that require secure bolted connections and high ripple-current handling.

Key Features

• Capacitance & Voltage — 68 mF (68,000 µF) rated at 80 V with ±20% tolerance (120 Hz, 20°C).
• Screw-Terminal Package — Radial can with screw terminals sized for φ90 devices; nominal bolt for φ90 is M5, providing a secured mechanical and electrical connection.
• Operating Temperature — Specified for −40°C to +105°C operation.
• Endurance / Load Life — Rated for 2000 hours at 105°C under rated ripple/current conditions.
• Ripple Current Capability — 17 A at 120 Hz and 19.55 A at 100 kHz to support high-ripple environments.
• Loss Tangent — tan δ specified at 0.4 (max.), enabling predictable dissipation characteristics.
• Physical Size & Pack — φ90 × 140 mm body; supplied in cardboard packing and indicated as mass production availability.
• Regulatory — RoHS compliant.
• Marking — White lettering on a black sleeve for clear identification.

Typical Applications

• General-purpose power systems — For engineers needing high-capacitance, high-voltage screw-terminal capacitors in bulk energy storage and DC bus applications where robust terminal connections are required.
• High-ripple environments — Suited to applications that demand significant ripple-current handling, as indicated by the specified 120 Hz and 100 kHz ripple-current ratings.
• High-temperature operation — Designed for systems that operate across a broad temperature range up to +105°C with defined endurance at elevated temperature.

Unique Advantages

• High stored energy in a single device — 68,000 µF at 80 V reduces the number of parallel capacitors required for large capacitance needs.
• Screw-terminal robustness — M5-compatible screw terminals on the φ90 can enable secure bolted connections for reliable mechanical and electrical performance.
• Defined high-temperature endurance — 2000-hour rating at 105°C provides a clear reliability target for thermal-stressed designs.
• Measured ripple capability — Explicit ripple-current specifications at both 120 Hz and 100 kHz help match the part to power systems with known ripple profiles.
• Clear identification and compliance — White-on-black sleeve marking and RoHS compliance simplify inventory control and regulatory fitment.
• Production-ready supply — Cardboard packed and listed as mass production, supporting repeatable procurement and assembly workflows.
