LGN2W680MELY25

The LGN2W680MELY25 is a polarized aluminum electrolytic capacitor in a snap-in terminal can, designed for general-purpose applications requiring a 450 V rated voltage and 68 µF capacitance. It delivers high-temperature endurance and compact sizing for power electronics and other equipment where robust ripple handling and long-term stability at elevated temperatures are required.

This part is specified for operation from −25 °C to 105 °C, is RoHS compliant, and is engineered to withstand 3000 hours of rated ripple current at 105 °C while maintaining defined electrical characteristics.

Key Features

• Capacitance and Voltage — 68 µF capacitance at a 450 V rated voltage, with polarization for DC applications and a capacitance tolerance of −20% to +20%.
• High-temperature Endurance — Rated for operation up to 105 °C and specified to withstand 3000 hours of DC bias plus rated ripple current at 105 °C (endurance conditions defined in the datasheet).
• Ripple Current Handling — Rated ripple current of 500 mA at 120 Hz and 715 mA at 100 kHz, supporting both low- and high-frequency ripple environments.
• Package and Mounting — Snap-in terminal, radial can package for secure board or chassis mounting; compact dimensions L: 2.5 cm × D: 2.0 cm and a smaller case size relative to the LGU series.
• Electrical Stability — Endurance and shelf-life limits: capacitance change within ±20% after specified endurance or shelf-life tests, tan δ within specified limits, and leakage current meeting I ≤ 3/√C (µA) after initial voltage application as defined in the datasheet.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronics — Suitable where a polarized 450 V, 68 µF capacitor with snap-in mounting is needed for power-related circuitry in general-purpose equipment.
• High-Temperature Environments — Intended for designs that require reliable operation and rated ripple endurance at elevated temperatures up to 105 °C.
• Compact Power Modules — Compact L: 2.5 cm × D: 2.0 cm can size and snap-in mounting make this capacitor appropriate for space-constrained power assemblies where a smaller-case alternative to LGU is desired.

Unique Advantages

• Long Endurance at 105 °C — Specified to withstand 3000 hours of rated ripple current and DC bias at 105 °C, providing predictable aging behavior under rated conditions.
• Dual-Frequency Ripple Performance — Rated ripple current values provided for both 120 Hz (500 mA) and 100 kHz (715 mA), enabling designers to evaluate performance across common ripple spectrums.
• Compact Snap-In Format — One rank smaller case than LGU with snap-in radial can package simplifies layout in compact power designs while maintaining secure mechanical mounting.
• Clear Reliability Criteria — Datasheet-specified limits for capacitance change, tan δ, and leakage current after endurance and shelf-life tests support predictable replacement and life-cycle planning.
• Regulatory Compliance — RoHS compliant to current directives, supporting environmentally regulated product builds.
