LGN2P681MELZ45

The LGN2P681MELZ45 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGN series, offering 680 µF capacitance at a 220 V rating. Designed for general‑purpose power applications, it provides robust ripple handling and long endurance in a compact snap‑in can package.

Key value comes from its 105°C rated operation with a 3000‑hour endurance, low leakage characteristics, and a compact φ22 × 45 mm footprint that supports high‑density power designs where reliable bulk capacitance and board‑level mounting are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with ±20% tolerance and a 220 V rated voltage suitable for mid‑voltage power rails.
• Ripple Current Performance — Handles 1.78 A at 120 Hz (low frequency) and 2.67 A at 100 kHz (high frequency), supporting smoothing and filtering under continuous ripple load.
• Leakage Current — Specified leakage current of 1160 µA, measured after rated voltage application conditions.
• Thermal & Reliability — Operates from −40°C to 105°C with an endurance rating of 3000 hours at 105°C under rated ripple/current conditions.
• Package & Mounting — Snap‑in radial can (polarized) in a compact φ22 × 45 mm (D × L) package; supplied in tray packing for production assembly.
• Regulatory — RoHS compliant.

Typical Applications

• Power supplies — Bulk energy storage and smoothing on 220 V rails where 680 µF capacitance and rated ripple current improve voltage stability.
• Industrial power equipment — Filtering and decoupling in equipment operating across −40°C to 105°C with long endurance requirements.
• Energy conversion systems — Supporting DC link and intermediate circuit filtering where high ripple capability at both low and high frequencies is needed.

Unique Advantages

• High ripple tolerance: Specified 1.78 A (120 Hz) and 2.67 A (100 kHz) ripple current ratings enable reliable handling of continuous AC ripple at typical switching and line frequencies.
• Extended high‑temperature life: 3000 hours at 105°C endurance provides predictable performance and service life in high‑temperature environments.
• Compact snap‑in package: φ22 × 45 mm radial can with snap‑in terminals offers a space‑efficient, board‑mountable solution for high‑capacitance requirements.
• Low leakage: 1160 µA leakage current supports applications where minimized self‑discharge and stable bias behavior are important.
• Production‑ready packaging: Tray packing and mass production status support scalable procurement and assembly workflows.
