LGU1K682MELC

The LGU1K682MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering 6800 µF (6.8 mF) capacitance at an 80 V rating. Designed for general‑purpose applications, it combines high ripple tolerance and long endurance for demanding thermal and electrical environments.

Key value propositions include a 3000‑hour endurance at 105°C under rated ripple conditions, robust ripple current capability across low and high frequencies, and a compact radial snap‑in can package for secure board mounting and automated handling.

Key Features

• Capacitance & Voltage — 6800 µF (6.8 mF) nominal capacitance with an 80 V rated voltage and capacitance tolerance of ±20% (–20% to +20%).
• High Temperature Endurance — Rated for operation from –40°C to 105°C with a specified lifetime of 3000 hours at 105°C under rated ripple and DC bias.
• Ripple Current Performance — Low‑frequency ripple current of 4.19 A at 120 Hz and high‑frequency ripple capability of 4.819 A at 50 kHz, supporting sustained ripple loading.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.20 measured at 20°C, 120 Hz for the 80 V rating, supporting stable AC performance.
• Leakage Current — Specified leakage current of 2210 µA (measured after rated voltage application conditions), suitable for power applications requiring defined leakage limits.
• Package & Mounting — Radial, snap‑in can package (φ35 × 45 mm) for reliable board seating and mechanical retention; supplied in tray packing for production handling.
• Regulatory Compliance — RoHS compliant, aligning with common environmental requirements.

Typical Applications

• General‑purpose power circuits — Bulk capacitance for power electronics where high ripple current handling and long thermal endurance at 105°C are required.
• Industrial power supplies — Energy storage and smoothing in general‑purpose industrial designs that demand sustained ripple performance and 3000‑hour endurance.
• Electronic assemblies requiring secure mounting — Snap‑in radial can package provides robust mechanical retention for boards exposed to vibration or thermal cycling.

Unique Advantages

• Long‑term high‑temperature reliability — 3000 hours endurance at 105°C under rated ripple current ensures predictable lifetime in elevated temperature applications.
• High ripple current capability — Specifies both low‑ and high‑frequency ripple current values (4.19 A at 120 Hz, 4.819 A at 50 kHz), enabling consistent performance across frequency ranges.
• Large capacitance in a compact can — 6800 µF in a φ35 × 45 mm radial snap‑in package provides high energy density where board space is constrained.
• Measured loss and leakage specifications — tan δ of 0.20 (20°C, 120 Hz) and defined leakage current help designers predict AC loss and quiescent current behavior.
• Production‑ready packaging — Tray packing and mass production status support procurement and assembly workflows for volume designs.
• Environmental compliance — RoHS compliance reduces material restriction risk in global markets.
