LGN2D681MELA30

The LGN2D681MELA30 is a snap-in terminal, large-can aluminum electrolytic capacitor from Nichicon's LGN series. It provides 680 µF capacitance at a 200 V rating in a compact φ25 × 30 mm can, designed for general-purpose power applications that require robust ripple handling and long operating life.

Engineered for high-temperature endurance, the LGN2D681MELA30 withstands rated ripple current for extended periods at 105°C and is supplied in tray packing for streamlined assembly and handling. The part is RoHS compliant and available in mass production.

Key Features

• Core Electrical — 680 µF capacitance with a rated voltage of 200 V and capacitance tolerance of ±20% (−20% ~ 20%).
• Ripple Performance — Low-frequency ripple current of 1.75 A (120 Hz) and high-frequency ripple current of 2.625 A (100 kHz) to support filtering and smoothing under dynamic loads.
• Loss and Leakage — tanδ (DF) specified at 0.15 (measured at 20°C, 120 Hz) and leakage current rated at 1100 µA.
• Reliability & Endurance — Designed to meet endurance requirements after 3000 hours at 105°C with DC bias plus rated ripple current; capacitance change and leakage remain within specified limits.
• Temperature Range — Operating range from −40°C to +105°C for broad environmental tolerance.
• Package & Mounting — Snap-in (radial, can) configuration in a compact φ25 × 30 mm case (tray packing) for secure board mounting and higher assembly throughput.
• Compliance — RoHS compliant.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in general-purpose power supplies where 200 V rating and high ripple current capability are required.
• Energy storage for power electronics — Local energy buffering in systems that require sustained ripple handling at elevated temperatures.
• Industrial and commercial equipment — General-purpose use in devices and modules that demand reliable high-temperature endurance and snap-in mounting for secure installation.

Unique Advantages

• High ripple-handling capability: Specified ripple currents of 1.75 A (120 Hz) and 2.625 A (100 kHz) support effective filtering across low and high frequency domains.
• Long high-temperature endurance: Endurance rated for 3000 hours at 105°C with DC bias plus rated ripple current reduces maintenance and replacement frequency in hot operating environments.
• Compact snap-in package: φ25 × 30 mm can size and snap-in terminals provide a space-efficient, mechanically robust solution for board-level mounting; available in tray packing for production handling.
• Predictable electrical performance: Specified tanδ (0.15 at 20°C, 120 Hz), leakage current, and ±20% capacitance tolerance simplify design margin calculations.
• RoHS compliant and in mass production: Meets environmental directives and is readily available for scaled production requirements.
