LGW2E681MELC25

The LGW2E681MELC25 from Nichicon is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications requiring high ripple current handling and elevated temperature endurance. As part of the LGW series, this polarized radial can provides 680 µF capacitance at a 250 V rating and is specified for continuous operation up to 105°C.

Engineered for designs that demand sustained ripple performance, the LGW2E681MELC25 withstands rated ripple current for extended periods while maintaining capacitance, dissipation factor, and leakage within datasheet limits.

Key Features

• Electrical Performance — 680 µF nominal capacitance at 250 V with tolerance of −20% to +20%; polarized construction for DC power applications.
• High Ripple Current Capability — Rated ripple currents include 2.55 A at 120 Hz and 3.825 A at 50 kHz, supporting designs with significant AC ripple on DC rails.
• Thermal Endurance — Specified for operation from −40 °C to 105 °C and guaranteed to withstand 3000 hours of rated ripple current at 105 °C with defined endurance limits on capacitance, tan δ and leakage.
• Package & Mounting — Radial, snap-in can package designed for secure board mounting and robust mechanical retention.
• Size — Compact footprint with dimensions L: 2.5 × D: 3.5 cm and a maximum seated height of 2.5 cm.
• Regulatory — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on DC power rails where high ripple currents and elevated operating temperatures are present.
• Power supply energy storage — Energy reservoir in power supply and auxiliary circuits that require stable capacitance under prolonged ripple stress.
• Industrial electronics — Use in equipment and modules that demand long ripple-current endurance at up to 105 °C.
