LGN2E681MELC25

The LGN2E681MELC25 from Nichicon is a snap-in, radial can aluminum electrolytic capacitor rated at 680 µF and 250 V. It is part of the LGN series and is designed for general-purpose power applications that require compact bulk capacitance with elevated temperature endurance.

Engineered for sustained performance, this capacitor supports operation from −40 °C to 105 °C and is specified to withstand 3000 hours of rated ripple current at 105 °C, delivering durable smoothing and energy-storage capability in compact snap-in form factors.

Key Features

• Electrical Performance — 680 µF nominal capacitance at 250 V with a tolerance of ±20% for bulk energy storage and smoothing in 250 V circuits.
• High Ripple Handling — Rated ripple current of 1.7 A at 120 Hz and 2.55 A at 100 kHz, specified under the LGN series endurance conditions.
• High-Temperature Endurance — Designed for operation from −40 °C to 105 °C and qualified to withstand 3000 hours of applied rated ripple current at 105 °C.
• Compact Snap-In Package — Radial, can-style snap-in mounting with dimensions L: 2.5 × D: 3.5 cm and a maximum seated height of 2.5 cm to save board space compared with larger cases.
• Reliability Metrics — Endurance criteria: capacitance change within ±20%, tan δ within 200% of initial, and leakage current at or below initial specified values after the 3000-hour test at 105 °C.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Supplies — Provides bulk capacitance and ripple filtering for 250 V circuits in general-purpose power designs.
• High-Temperature Power Environments — Suitable where sustained elevated-temperature operation is required, backed by a 3000-hour rating at 105 °C under rated ripple conditions.
• Compact Power Modules — Snap-in radial can package and compact L: 2.5 × D: 3.5 cm footprint for space-constrained assemblies that require robust bulk capacitance.

Unique Advantages
