LNT2V681MSEFBN

The LNT2V681MSEFBN is an aluminum electrolytic capacitor in Nichicon’s LNT series, configured with screw terminals for secure, high-current connections. With a 680 µF capacitance at 350 V, a rated operating range of –25°C to 105°C, and a 5,000-hour life at 105°C, it is designed for general-purpose applications that require high-voltage bulk capacitance and durable thermal endurance.

Key Features

• Capacitance & Voltage — 680 µF at a 350 V rated voltage, offering substantial energy storage for high-voltage circuits.
• Screw-terminal package — Radial can with screw terminals simplifies secure mounting and high-current connections for robust assemblies.
• High-temperature endurance — Rated for operation from –25°C to 105°C with a load life of 5,000 hours at 105°C when subjected to rated ripple current.
• Loss characteristics — Specified tanδ 0.2 (measurement at 120 Hz, 20°C) and defined impedance behavior at low temperatures for predictable AC performance.
• Ripple current capability — Defined ripple current ratings of 4.1 A at 120 Hz and 5.74 A at 100 kHz to support both low- and high-frequency ripple conditions.
• Polarized, tolerance and dimensions — Polarized capacitor with ±20% tolerance; package dimensions approximately φ51 × 80 mm (L: 8 × D: 5.1 cm) and height seated max 3.15 inch.
• RoHS compliant — Conforms to RoHS requirements as indicated for the LNT series.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage in high-voltage supplies up to 350 V, benefiting from 680 µF capacitance and defined ripple current ratings.
• Industrial equipment — Use where durable high-temperature operation (–25°C to 105°C) and screw-terminal mounting are required for secure connections and long service life.
• High-voltage DC link and filter circuits — Designed for DC link and filtering roles that need 350 V rating and documented ripple performance at both 120 Hz and 100 kHz.

Unique Advantages

• High-voltage capability: 350 V rating enables use in elevated-voltage applications without additional series stacking.
• Documented long life: 5,000-hour endurance at 105°C under rated ripple current provides predictable aging and maintenance planning.
• Screw-terminal reliability: Robust terminal design supports secure electrical and mechanical connections for higher current and repeated service access.
• Frequency-aware ripple ratings: Specified ripple current at both 120 Hz and 100 kHz supports designers addressing low- and high-frequency ripple environments.
• Thermal performance: Rated operation down to –25°C and up to 105°C with defined impedance ratios, enabling stable behavior across a wide temperature span.
• Regulatory compliance: RoHS compliance aligns the component with common environmental requirements.
