LGN2D681MELZ40

The LGN2D681MELZ40 is a Nichicon LGN series aluminum electrolytic capacitor in a snap-in terminal radial can. It provides 680 µF capacitance at 200 V with snap-in mounting and is designed for general-purpose electronic applications.

Engineered for elevated-temperature operation and sustained ripple handling, this capacitor withstands rated ripple current for 3000 hours at 105°C while offering a compact, smaller-sized case compared with the LGU series. It is RoHS compliant.

Key Features

• Core Electrical Specs — 680 µF nominal capacitance with ±20% tolerance and a rated voltage of 200 V; polarized design for DC applications.
• High-Temperature Endurance — Rated for operation to 105°C and specified to withstand 3000 hours of rated ripple current at 105°C.
• Ripple Current Performance — Rated ripple current of 1.75 A at 120 Hz and 2.625 A at 100 kHz, supporting sustained ripple-handling in demanding supply conditions.
• Package and Mounting — Snap-in terminal radial can for secure board installation; compact footprint with dimensions approximately L: 4 × D: 2.2 cm and one rank smaller case size than the LGU series.
• Electrical Reliability Parameters — Series-level specifications include leakage current I ≤ 3/√(C) µA after 5 minutes at 20°C and defined limits on tan δ for quality assurance.
• Environmental Compliance & Identification — RoHS compliant (2011/65/EU, (EU)2015/863) and marked with white lettering on a black sleeve.

Typical Applications

• General-purpose electronics — Intended for use where a rugged snap-in aluminum electrolytic capacitor is required for bulk capacitance and smoothing at up to 200 V.
• Power supplies — Bulk filtering and ripple suppression in power-supply circuits that demand sustained ripple endurance at elevated temperatures.
• Industrial equipment — Suitable for general-purpose industrial designs that require high-temperature endurance and reliable long-term performance.

Unique Advantages

• Long high-temperature life: Specified endurance of 3000 hours at 105°C under rated ripple current supports reliable performance in elevated-temperature environments.
• Compact, space-saving case: One rank smaller case size than LGU-series parts enables tighter layouts without sacrificing capacitance.
• Defined ripple capability: Explicit ripple ratings at 120 Hz and 100 kHz let designers quantify thermal and stress margins for filtering and decoupling.
• Clear electrical limits: Series leakage-current and tan δ specifications provide measurable acceptance criteria for production and QA.
• RoHS compliant: Meets current RoHS directive requirements for materials compliance.
