LNT2G681MSEFBN

The LNT2G681MSEFBN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It combines a 680 µF capacitance with a 400 V rated voltage in a radial can with screw terminals for secure electrical and mechanical connections.

Engineered for sustained operation up to +105°C with a rated endurance of 5,000 hours, this RoHS-compliant, mass-production component addresses designs that require high-voltage bulk capacitance, defined ripple handling, and robust mounting via M5 screw terminals.

Key Features

• Electrolytic Core Aluminum electrolytic construction providing 680 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• High Voltage Rating Rated for 400 V DC for applications that require elevated working voltages.
• Ripple Current Capability Rated low-frequency ripple current of 4.20 A at 120 Hz and high-frequency ripple current of 5.88 A at 100 kHz, supporting circuits with continuous ripple demands.
• Electrical Loss and Leakage Specified dissipation factor (tan δ) of 0.2 (measured at 120 Hz) and leakage current of 1,560 µA as provided in the product data.
• Thermal and Lifetime Performance Rated operating range from −25°C to +105°C with an endurance/load life of 5,000 hours at +105°C under rated ripple and bias conditions.
• Screw-Terminal Package Radial can with screw terminals (φ51 size); nominal terminal bolt size M5 and terminal pitch W = 22.0 mm for the φ51 variant, enabling secure connections and straightforward mounting.
• Form Factor Physical dimensions φ51 × 80L (approx. L: 8.0 cm × D: 5.1 cm) and packaged in cardboard for mass-production shipping and handling.
• Regulatory RoHS compliant as stated in the product data.

Typical Applications

• General-purpose power systems — Where a 400 V, 680 µF aluminum electrolytic with screw terminals is required for bulk capacitance and robust connections.
• Industrial power electronics — Suitable for equipment designs that specify a screw-terminal capacitor rated to +105°C and a 5,000-hour endurance.
• Energy buffering and smoothing — For designs needing defined ripple-current handling at both low (120 Hz) and high (100 kHz) frequencies.
• Rack-mounted or panel installations — φ51 screw-terminal format with M5 bolts for secure mechanical mounting in larger assemblies.

Unique Advantages

• High-voltage bulk capacitance: 400 V rating combined with 680 µF provides substantial energy storage for high-voltage rails.
• Defined ripple performance: Specified ripple currents at 120 Hz and 100 kHz allow designers to match capacitor selection to expected ripple environments.
• Robust mechanical termination: Screw-terminal construction with M5 nominal bolt size enables reliable electrical and mechanical connections in industrial assemblies.
• High-temperature endurance: 5,000-hour load-life at +105°C supports long-term operation in elevated-temperature environments.
• Measured electrical characteristics: Provided tan δ (0.2) and leakage current (1,560 µA) values allow predictable performance verification during design and testing.
• Production-ready supply: Listed as mass production status and shipped in cardboard packaging for volume deployment.
