LNT2C683MSEN

The LNT2C683MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNT series designed for high‑capacitance, high‑voltage power applications. It provides 68,000 µF nominal capacitance at a 160 V rating in a radial can with screw terminals, intended for bulk energy storage, filtering and decoupling in industrial power systems and power conversion equipment.

Key value propositions include large capacitance at elevated voltage, robust ripple‑current handling, and endurance for high‑temperature operation up to 105°C, making it suitable where sustained high energy buffering and reliable performance under load are required.

Key Features

• High Capacitance — 68,000 µF (68 mF) nominal capacitance for substantial energy storage and bulk filtering.
• Rated Voltage — 160 V DC rating suitable for medium‑voltage power rails and converters.
• Screw‑Terminal, Radial Can Package — Screw terminal mounting with a radial can package; for the φ100 size the terminal uses an M8 nominal bolt, simplifying robust mechanical and electrical connections.
• Temperature Range & Endurance — Operational from −25°C to +105°C with a rated endurance of 2,000 hours at 105°C under rated ripple conditions.
• Ripple‑Current Capability — Low‑frequency ripple current 19.2 A at 120 Hz and high‑frequency ripple current 23.04 A at 100 kHz to support demanding power conditioning loads.
• Electrical Characteristics — Capacitance tolerance ±20% at 120 Hz/20°C and tan δ = 0.25 (20°C, 120 Hz) for predictable impedance behavior.
• Leakage Current — Specified leakage current 5,000 µA after standard voltage application, supporting predictable standby losses.
• Packaging & Production — Supplied in cardboard packing; part is in mass production.
• RoHS Compliant — Conforms to RoHS directives as noted for the LNT series.

Typical Applications

• Power Supplies and DC‑DC Converters — Bulk energy storage and output filtering on medium‑voltage rails where large capacitance and high ripple capability reduce voltage ripple and support transient loads.
• Industrial Drives and Motor Control — Energy buffering and smoothing in drive DC buses and regenerative systems requiring high capacitance and reliable screw‑terminal connections.
• Uninterruptible Power and Backup Systems — Bulk capacitance for short‑term energy hold‑up and power conditioning in backup or ride‑through subsystems.

Unique Advantages

• Extensive Energy Storage: 68,000 µF at 160 V delivers significant bulk capacitance in a single device, reducing the number of parallel parts required.
• High Ripple Endurance: Specified LF and HF ripple currents (19.2 A at 120 Hz, 23.04 A at 100 kHz) enable use on noisy or high‑frequency power rails with known thermal margining.
• Designed for Elevated Temperatures: Rated to +105°C with a defined 2,000‑hour endurance at that temperature for 160 V class parts, supporting high‑temperature installations.
• Robust Mechanical Termination: Screw terminal construction (M8 nominal bolt for the φ100 size) provides secure, low‑resistance connections for high‑current applications.
• Predictable Electrical Performance: Defined tan δ and leakage current specifications enable easier system power‑loss and thermal budgeting.
• RoHS Compliance: Conforms to RoHS directives as specified for the LNT series, aiding regulatory alignment.
