LNT2G681MSEF

The LNT2G681MSEF is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, rated 400 V with 680 µF capacitance and ±20% tolerance. Engineered for general-purpose power applications, it combines high voltage handling, substantial ripple-current capability and a long endurance rating for reliable bulk energy storage and smoothing in industrial and power-electronics designs.

Key value propositions include a 105°C endurance rating with 5,000 hours life at rated conditions, high low- and high-frequency ripple current capability, and robust screw-terminal mounting for secure, low-resistance electrical and mechanical connections.

Key Features

• Rated Capacitance and Tolerance — 680 µF with ±20% tolerance at 120 Hz, 20°C, suitable for bulk filtering and energy storage needs.
• High Voltage Rating — 400 V rated voltage for high-voltage DC link and power-supply applications.
• High Temperature Endurance — Designed for operation from −25°C to +105°C with a rated lifetime of 5,000 hours at 105°C under specified ripple and bias conditions.
• Robust Screw-Terminal Package — Radial can with screw terminals provides secure electrical connections and mechanical stability for high-current, high-vibration environments; package size φ51 × 80 mm.
• Low-Frequency and High-Frequency Ripple Capability — Rated ripple currents of 4.20 A at 120 Hz and 5.88 A at 100 kHz support both mains-frequency smoothing and higher-frequency decoupling.
• Leakage Current and Dissipation Factor — Specified leakage current of 1560 µA and tan δ of 0.2 (measured at 20°C, 120 Hz), enabling predictable loss and self-discharge behavior.
• RoHS Compliant / Mass Production — RoHS-compliant and available in mass-production quantities for volume designs.

Typical Applications

• General Purpose Power Systems — Bulk energy storage and smoothing in power supplies and DC link circuits where 400 V rating and high ripple capability are required.
• Industrial Power Electronics — Filtering and decoupling in inverters, motor drives or other industrial equipment benefiting from screw-terminal mounting and high-temperature endurance.
• High-Voltage Capacitor Banks — Use in stacked or banked capacitor arrangements that require secure bolt-down terminals and predictable lifetime at 105°C.

Unique Advantages

• High-Voltage, High-Capacitance Combination — 400 V and 680 µF provide significant stored energy in a compact screw-terminal can for designs that need elevated DC voltage handling.
• Designed for High-Temperature Endurance — 5,000 hours at 105°C supports long-term operation under elevated temperature and ripple stress, reducing replacement frequency during service life.
• Dual-Frequency Ripple Performance — Specified ripple currents at both 120 Hz and 100 kHz allow predictable performance across mains-frequency smoothing and higher-frequency decoupling duties.
• Secure Mechanical and Electrical Connection — Screw-terminal construction simplifies installation in high-current or vibration-prone environments and supports robust busbar or cable connections.
• Predictable Loss and Leakage — Specified tan δ and leakage current figures enable accurate thermal and self-discharge budgeting in system-level designs.
• Production-Ready Supply — RoHS compliance and mass-production status support volume procurement and deployment.
