LGN2C681MELY40

The LGN2C681MELY40 is a Nichicon LGN series aluminum electrolytic capacitor in a radial snap‑in can. It delivers 680 µF at 160 V in a compact snap‑in package optimized for general‑purpose electronic applications.

Designed for high‑temperature operation, this part is rated to operate from −40 °C to 105 °C and withstands 3000 hours of rated ripple current at 105 °C, offering reliable long‑term performance in demanding environments. The component is RoHS compliant.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance, rated at 160 V DC for energy storage and smoothing in general‑purpose circuits.
• High‑temperature endurance: Rated operating range −40 °C to 105 °C with endurance verification of 3000 hours at 105 °C under DC bias plus rated ripple current.
• Ripple current performance: Rated ripple current of 1.7 A at 120 Hz and 2.55 A at 100 kHz, suitable for sustained ripple handling in power applications.
• Compact snap‑in package: Radial, can snap‑in mounting for secure PCB installation; physical size 20 × 40 mm (φD × L) to save board area compared with larger case sizes.
• Electrical stability: Capacitance tolerance ±20%; datasheet endurance criteria specify capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current not exceeding initial specified value after endurance testing.
• Leakage current and dissipation: Leakage current specified per datasheet after 5 minutes’ application of rated voltage at 20 °C (I ≤ 3/√C µA, C = rated capacitance in µF); tangent of loss angle (tan δ) max. 0.15 at 160–420 V (measured at 120 Hz, 20 °C).
• Regulatory compliance: Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic circuits: Provides bulk capacitance and filtering where a 680 µF, 160 V snap‑in solution is required.
• High‑temperature systems: Suited for equipment and assemblies that require operation up to 105 °C and reliable ripple endurance over extended periods.
• Compact power modules: Useful where a one‑rank smaller case size than the LGU series helps reduce board or chassis footprint while retaining robust performance.

Unique Advantages

• Proven ripple endurance: Withstands 3000 hours of rated ripple current at 105 °C, providing predictable lifetime behavior under sustained stress.
• Compact footprint: 20 × 40 mm can reduces overall assembly size compared with larger LGU‑series cases while maintaining the same rated voltage and capacitance.
• Broad temperature rating: −40 °C to 105 °C operating range suits a wide set of general‑purpose and industrial environments.
• Dual‑frequency ripple specs: Explicit ripple current numbers at both 120 Hz (1.7 A) and 100 kHz (2.55 A) enable designers to evaluate performance across common power conversion frequencies.
• Verified electrical stability: Endurance and shelf‑life criteria in the datasheet define allowable capacitance change, tan δ, and leakage current after stress, supporting predictable design margins.
• RoHS compliant: Meets current RoHS requirements for restricted substances.
