LGU1J682MELB

The LGU1J682MELB is a snap‑in aluminum electrolytic capacitor from Nichicon's LGU series, offering 6.8 mF capacitance at a 63 V rating in a compact φ30 × 50 mm can. Designed for general‑purpose power applications, it combines high capacitance, robust ripple handling and extended endurance for use in designs that require sustained performance at elevated temperatures.

Key value propositions include long endurance under rated ripple at 105°C, RoHS compliance, and a snap‑in radial can package that simplifies installation in power subsystems and assemblies.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a rated voltage of 63 V and capacitance tolerance of −20% to +20%.
• High Temperature Endurance — Rated for operation from −40°C to +105°C with a life/endurance specification of 3000 hours at 105°C under rated ripple conditions.
• Robust Ripple Handling — Low‑frequency ripple current of 3.73 A at 120 Hz and high‑frequency ripple current of 4.29 A at 50 kHz, supporting sustained AC stress in power circuits.
• Low Loss Characteristics — Loss tangent (tan δ) of 0.25 measured at 20°C and 120 Hz for predictable dissipation characteristics during operation.
• Leakage Current — Measured leakage current of 1960 µA, specified per the product data.
• Package & Mounting — Snap‑in radial can (φ30 × 50 mm), tray packed for production handling and board insertion.
• Regulatory — RoHS compliant.

Typical Applications

• General‑purpose power systems — Provides bulk energy storage and smoothing where a high capacitance (6.8 mF) and 63 V rating are required.
• High‑ripple DC/DC stages — Suitable where sustained ripple currents up to 3.73 A (120 Hz) or 4.29 A (50 kHz) are present, helping stabilize output under load.
• Industrial and electronic assemblies — Snap‑in, radial can package enables secure mounting in power assemblies and chassis‑mounted designs.

Unique Advantages

• Extended endurance at elevated temperature — 3000‑hour life rating at 105°C under rated ripple current supports long‑term reliability in hot operating environments.
• High capacitance in a compact can — 6800 µF in a φ30 × 50 mm footprint delivers substantial bulk capacitance with a small board/chassis area impact.
• Strong ripple performance — Specified low‑ and high‑frequency ripple currents let designers quantify thermal and lifetime impact across operating frequencies.
• Predictable dissipation — Specified tan δ (0.25 at 20°C, 120 Hz) assists in thermal budgeting and loss calculations during system design.
• Production‑ready packaging — Tray packing supports efficient handling and assembly in production environments.
• RoHS compliant — Aligns with lead‑restriction requirements for regulated markets.
