LGN2E681MELA40

The LGN2E681MELA40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series. It provides a polarized 680 µF capacitance at a 250 V rating in a compact radial can with snap‑in mounting.

Designed for general‑purpose applications, this capacitor delivers long high‑temperature endurance and measurable ripple handling, making it suitable where stable bulk capacitance and reliability at elevated temperatures are required.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, suitable for polarized DC applications.
• High‑Temperature Endurance: Rated for operation from −40 °C to +105 °C with a specified endurance of 3000 hours at 105 °C under rated ripple conditions.
• Snap‑in Radial Package: Snap‑in terminal type in a radial can package for robust mechanical mounting and straightforward PCB assembly.
• Ripple Current Capability: Specified ripple performance of 1.7 A at 120 Hz and 2.55 A at 100 kHz, enabling effective handling of AC ripple in DC circuits.
• Compact Dimensions: Physical size given as L: 4 × D: 2.5 cm with a maximum seated height of 1.575 inch, offering a smaller case size relative to the LGU series.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose DC Systems: Use where a polarized 680 µF, 250 V capacitor is required for bulk energy storage or decoupling on DC rails.
• High‑Temperature Installations: Suited to equipment operating up to 105 °C thanks to 3000‑hour endurance at that temperature under rated ripple conditions.
• Board‑Mounted Power Modules: Snap‑in radial can package provides secure mounting for power supply modules and assemblies requiring robust mechanical retention.

Unique Advantages

• Long High‑Temperature Life: 3000 hours endurance at 105 °C under rated ripple current supports long service intervals in elevated‑temperature environments.
• Confirmed Ripple Specs: Ripple current ratings at both low (120 Hz) and high (100 kHz) frequencies (1.7 A and 2.55 A respectively) provide measurable performance metrics for design verification.
• Smaller Case Than LGU: One rank smaller case size compared to the LGU series, enabling tighter spacing and reduced enclosure volume where size is constrained.
• Snap‑in Mechanical Stability: Snap‑in terminal mounting offers reliable board retention for installations subject to vibration or mechanical stress.
• Regulatory Compliance: RoHS compliance supports deployment in regions requiring EU restricted‑substance conformity.
