LNT2E681MSE

The LNT2E681MSE is a Nichicon LNT series aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It provides 680 µF capacitance at a 250 V rating, with polarized construction and a ±20% tolerance.

Engineered for elevated operating temperatures, this part is rated to +105°C with a specified endurance of 2000 hours at 105°C. Key electrical characteristics include measured tanδ, defined leakage current, and ripple-current ratings for both low and high frequency operation.

Key Features

• Electrical performance — 680 µF capacitance at a 250 V rated voltage with ±20% tolerance, suitable for bulk energy storage and smoothing in DC circuits.
• Ripple current capability — Low-frequency ripple current of 1.4 A (120 Hz) and high-frequency ripple current of 1.68 A (100 kHz) to support dynamic load conditions.
• Loss and leakage characteristics — Tan δ specified at 0.15 (20°C, 120 Hz) and leakage current measured at 1230 µA after rated voltage application, enabling predictable dissipation and standby behavior.
• Endurance and temperature range — Rated for operation from −25°C to +105°C with a load life (endurance) of 2000 hours at 105°C under rated ripple/current conditions.
• Mechanical and mounting — Screw terminal radial can with dimensions φ35 × 80 mm (L: 8 cm × D: 3.5 cm), providing secure bolted connections for higher-current and serviceable assemblies.
• Compliance and packaging — RoHS compliant and supplied in cardboard packing; part is in mass production under the Nichicon LNT series.

Typical Applications

• General-purpose power filtering — Used for smoothing and decoupling in DC power rails where 250 V, 680 µF capacity and screw-terminals are required.
• Industrial power supplies — Applicable in power modules and assemblies that need rated ripple handling and elevated temperature endurance.
• Bulk energy storage in control systems — Provides bulk capacitance for systems requiring polarized, high-voltage capacitors with robust terminal connections.

Unique Advantages

• High-temperature endurance: Rated to +105°C with 2000 hours life at that temperature, enabling reliable operation in elevated-heat environments.
• Dual-frequency ripple ratings: Specified ripple current at both 120 Hz and 100 kHz (1.4 A and 1.68 A), allowing selection based on low- or high-frequency ripple loading.
• Screw-terminal mounting: Provides secure, serviceable connections for higher-current paths and simplifies replacement or maintenance.
• Predictable electrical behavior: Specified tanδ (0.15 at 20°C) and defined leakage current (1230 µA) support accurate thermal and leakage budgeting in designs.
• Regulatory readiness: RoHS compliant to meet environmental directive requirements for manufactured assemblies.
• Production-ready availability: Listed as mass production, suitable for volume procurement and consistent supply planning.
