LNT2G681MSEFBB

The LNT2G681MSEFBB is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for general‑purpose power applications. It delivers 680 µF capacitance at a 400 V rated voltage and is built to operate across −25°C to +105°C with a 5,000‑hour endurance at 105°C.

With high ripple‑current capability, low leakage current and a robust screw terminal package, this Nichicon LNT series part is intended for designs that require high‑voltage energy storage, steady filtering and reliable long‑term operation in industrial and commercial equipment.

Key Features

• Capacitance and Tolerance — 680 µF nominal capacitance with ±20% tolerance measured at 120 Hz, 20°C.
• High Voltage Rating — 400 V rated voltage suitable for high‑voltage DC bus and energy‑storage roles.
• High Ripple‑Current Capability — 4.2 A at 120 Hz (low frequency) and 5.88 A at 100 kHz (high frequency), supporting sustained ripple handling.
• Electrical Losses and Leakage — tan δ specified at 0.2 (measurement at 120 Hz) and leakage current rated at 1,560 µA, enabling predictable performance in filtering and smoothing circuits.
• Thermal Endurance — Rated operating range −25°C to +105°C with a load life of 5,000 hours at 105°C per LNT series specifications.
• Robust Mechanical Package — Radial can with screw terminals (φ51 × 80 mm) for secure electrical connections and easy mounting in high‑current applications.
• Compliance and Packaging — RoHS‑compliant and supplied in cardboard packing for mass production handling.

Unique Advantages

• High‑voltage energy storage: 400 V rating provides headroom for DC bus and high‑voltage filter applications where compact capacitance is required.
• Strong ripple performance: Specified ripple currents at both low and high frequencies reduce operating temperature rise under AC stress and improve system stability.
• Long life at elevated temperature: 5,000 hours endurance at 105°C supports extended maintenance intervals and predictable aging in thermally stressed environments.
• Screw‑terminal reliability: M5 screw terminals and radial can construction enable dependable, low‑impedance connections for high‑current assemblies.
• Predictable electrical behavior: Specified tan δ and leakage current figures allow accurate modeling of losses and standby drain in power designs.
• Manufacturing readiness: RoHS compliance and cardboard packing support volume production and regulatory requirements.
