LGU2F681MELC

The LGU2F681MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package. It delivers 680 µF at a 315 V rating with polarized construction and ±20% tolerance, designed for general‑purpose use where bulk capacitance and sustained ripple handling are required.

Key value is long‑term thermal endurance: the part is specified to withstand 3000 hours of rated ripple current at 105 °C and is RoHS compliant, providing a reliable capacitor solution for demanding operating conditions up to 105 °C.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 315 V, ±20% tolerance (measured at 120 Hz, 20 °C).
• High‑temperature Endurance — Endurance rating: 3000 hours at 105 °C with D.C. bias plus rated ripple current; capacitance change within ±20% and leakage current ≤ initial specified value after test.
• Ripple Current Performance — Rated ripple current of 2.17 A at 120 Hz and 3.103 A at 50 kHz, with frequency coefficients defined by the LGU series for higher frequency operation.
• Operating Temperature Range — Specified for operation from −25 °C to +105 °C for the 315 V range.
• Package & Mounting — Snap‑in radial can (snap‑in terminal type) for secure board mounting; nominal dimensions L: 4.0 cm × D: 3.5 cm, seated height max 1.575 inches.
• Leakage & Loss Characteristics — Leakage current specified by I ≤ 3·C·V (µA) after 5 minutes at 20 °C; tan δ values per rated voltage are provided in the LGU series specification.
• RoHS Compliance & Marking — Compliant with RoHS directives and marked with white letters on a black sleeve for clear identification.

Typical Applications

• General‑purpose power filtering — Bulk capacitance and rated ripple handling make this unit suitable where stabilized DC filtering is required.
• Industrial electronic equipment — Designed for continuous operation at elevated temperature (up to 105 °C) and extended ripple exposure (3000 h endurance).
• Power supply energy storage — High voltage (315 V) and sizable capacitance support energy buffering in mid‑to‑high voltage circuits.

Unique Advantages

• Extended high‑temperature life — 3000 hours at 105 °C under rated ripple current reduces frequency of replacement and maintenance in high‑stress environments.
• High voltage capability — 315 V rating enables use in higher‑voltage power rails without stepping up to larger or multiple parts.
• Robust ripple handling — Specified ripple current values at both low and high frequencies allow confident selection based on application frequency profile.
• Secure snap‑in mounting — Snap‑in terminal design provides stable mechanical retention for vertical/horizontal board layouts.
• Regulatory compliance — RoHS compliance supports use in regions and products where restricted substances must be controlled.
