LGU2W680MELY

The LGU2W680MELY from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series designed for general‑purpose power applications. It delivers 68 µF nominal capacitance at a rated voltage of 450 V in a compact φ20 × 35 mm can with snap‑in mounting for secure board attachment.

Engineered to operate up to 105°C with a guaranteed 3000‑hour endurance under rated ripple current, this capacitor targets designs that require sustained high‑voltage smoothing, filtering and energy storage with controlled leakage and dissipation characteristics.

Key Features

• Snap‑in Terminal Package Robust radial snap‑in can for quick, reliable board mounting and mechanical stability in high‑current assemblies.
• 450 V Rated Voltage High working voltage capability (450 V) for high‑voltage power rails and DC link applications.
• 68 µF Capacitance, ±20% Tolerance Nominal capacitance of 68 µF with industry standard ±20% tolerance measured at 120 Hz, 20°C.
• High Temperature Endurance Rated for operation from −25°C to +105°C and qualified for 3000 hours at 105°C under rated ripple current.
• Ripple Current and Loss Characteristics Low frequency ripple current of 560 mA (120 Hz) and high frequency ripple current of 800.8 mA (50 kHz); tanδ (DF) = 0.20 at 20°C, 120 Hz.
• Low Leakage Current Specified leakage current of 520 µA (measured after voltage application as defined in the datasheet conditions).
• RoHS Compliant Manufactured in compliance with RoHS directive requirements.

Typical Applications

• General‑purpose power supplies — Use for smoothing and energy storage on high‑voltage DC rails where 450 V capability is required.
• Industrial power electronics — Suitable for assemblies requiring durable high‑temperature performance (−25°C to 105°C) and long endurance at rated ripple current.
• DC link and filtering — Employed where controlled leakage and defined dissipation (tanδ) are important for predictable circuit behavior.

Unique Advantages

• High‑voltage capability: 450 V rating enables use on demanding DC rails without additional series stacking.
• Designed for sustained ripple: Specified ripple current ratings and the 3000‑hour endurance at 105°C mean predictable performance in continuous ripple environments.
• Compact snap‑in form factor: φ20 × 35 mm can with snap‑in terminals provides a space‑efficient solution for board‑level integration.
• Verified dissipation and leakage: tanδ = 0.20 (120 Hz, 20°C) and measured leakage current (520 µA) provide clear electrical parameters for design validation.
• Compliance and manufacturability: RoHS compliance and tray packaging support regulatory requirements and high‑volume assembly processes.
