LGU2F681MELB

The LGU2F681MELB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, providing 680 µF of bulk capacitance at a rated voltage of 315 V. Designed for general‑purpose power applications, it delivers high‑voltage bulk energy storage with long thermal endurance for sustained performance at elevated temperatures.

Key value comes from its 3,000‑hour endurance rating at 105°C, robust ripple current capability across low and high frequencies, and a compact radial snap‑in can package for reliable board‑level installation.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with a 315 V rated voltage, suitable for high‑voltage bulk energy storage in general‑purpose power designs.
• Endurance — Rated for 3,000 hours at 105°C under specified conditions, providing long thermal life for continuous high‑temperature operation.
• Ripple Current Handling — Low‑frequency ripple current of 2.17 A at 120 Hz and high‑frequency ripple current of 3.103 A at 50 kHz, supporting demanding ripple environments.
• Leakage & Loss — Specified leakage current of 1,380 µA and tangent of loss angle (tan δ) measured at 20°C, 120 Hz; for the 315 V rating the tan δ specification is 0.15 (max) at the measurement condition.
• Mechanical & Mounting — Snap‑in terminal, radial can (snap‑in) package for secure, repeatable board mounting and efficient assembly; packaged in tray packing for production handling.
• Temperature Range & Tolerance — Operating temperature from –25°C to +105°C with capacitance tolerance of ±20% at 20°C, 120 Hz.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in power supplies and converters where high voltage and substantial capacitance are required.
• Energy storage — Local bulk energy reservoir for systems requiring sustained supply during transient loads at elevated temperatures.
• High‑frequency ripple environments — Circuits subject to significant ripple across a wide frequency range, leveraging specified ripple current ratings at 120 Hz and 50 kHz.
