LGN2P681MELB30

The LGN2P681MELB30 is a 680 µF, 220 V aluminum electrolytic capacitor in a snap‑in terminal (radial can) package, designed for general‑purpose power applications. It is a smaller‑sized member of the Nichicon LGN series, built for elevated‑temperature operation up to 105 °C and long‑term ripple endurance.

Key value propositions include high ripple handling, extended 105 °C service life, and compact snap‑in packaging for robust mounting in power assemblies and industrial equipment.

Key Features

• Electrical Rating — 680 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High Temperature Endurance — Rated for operation from −40 °C to 105 °C and specified to withstand 3000 hours application of rated ripple current at 105 °C.
• Ripple Current Capability — Specified ripple current handling of 1.78 A at 120 Hz and 2.67 A at 100 kHz to support power filtering under load.
• Loss and Leakage Characteristics — Series datasheet specifies tan δ limits (max. 0.15 for 160–420 V range at 120 Hz, 20 °C) and leakage current I ≤ 3/√C (µA) after 5 minutes at 20 °C.
• Endurance & Shelf Life — Endurance: capacitance change within ±20% and tan δ ≤ 200% of initial after 3000 hours at 105 °C; shelf life specified for 1000 hours at 105 °C with subsequent voltage treatment per JIS.
• Package & Mounting — Snap‑in radial can design (radial, can - snap‑in) for secure board retention in power modules and assemblies; size dimension L: 3 × D: 3 cm with a seated height max of 1.181 inches.
• RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply bulk filtering — Bulk energy storage and smoothing for 220 V power conversion circuits where elevated temperature endurance and ripple handling are required.
• Industrial power modules — DC link and smoothing in industrial equipment subjected to high ambient temperatures up to 105 °C.
• Commercial power electronics — Filtering and decoupling in commercial power systems and assemblies that benefit from snap‑in mounting for mechanical stability.

Unique Advantages

• Long high‑temperature life — Specified to endure 3000 hours of rated ripple current at 105 °C, supporting reliable operation in hot environments.
• Compact, smaller case size — One rank smaller case than LGU series parts, enabling denser power assemblies without sacrificing ripple performance.
• Robust ripple performance — Rated ripple current figures at both low and high frequencies (1.78 A at 120 Hz; 2.67 A at 100 kHz) for versatile use across switching and line‑frequency applications.
• Secure snap‑in mounting — Radial, can snap‑in package provides durable board retention for power modules and heavy‑load assemblies.
• Predictable electrical stability — Endurance and shelf‑life specifications tied to capacitance, tan δ, and leakage current provide designers with verifiable long‑term performance metrics.
• RoHS compliance — Aligns with environmental and regulatory requirements for commercial and industrial products.
