LGN2D182MELC40

The LGN2D182MELC40 from Nichicon is an aluminum electrolytic capacitor in a snap‑in, radial can package designed for general-purpose electronic applications. It delivers 1.8 mF capacitance at a 200 V rating with polarized terminals and snap‑in mounting for secure chassis or board installation.

Engineered for sustained operation up to 105°C, this part withstands 3000 hours of rated ripple current at 105°C and is RoHS compliant, offering a compact, durable option where elevated temperature endurance and high ripple handling are required.

Key Features

• Capacitance and Tolerance — 1.8 mF nominal capacitance with tolerance of -20% to +20% (±20%).
• Rated Voltage — 200 V DC rated voltage suitable for higher-voltage general‑purpose designs.
• High Temperature Endurance — Withstands 3000 hours application of rated ripple current at 105°C; endurance criteria include capacitance change within ±20%, tan δ within 200% of initial spec, and leakage current at or below initial specified value.
• Ripple Current Capability — Rated ripple current: 3.08 A at 120 Hz and 4.62 A at 100 kHz, supporting elevated ripple environments.
• Operating Temperature Range — −40°C to +105°C for reliable operation across a wide thermal range.
• Package and Mounting — Radial, can-style snap‑in package; physical size L: 4 × D: 3.5 cm with a maximum seated height of 1.575 inch for compact installations.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Series Characteristics — Part of Nichicon’s LGN series, offering a one-rank smaller case size relative to the LGU series where board space is limited.

Typical Applications

• General-purpose electronic equipment — Use where a 200 V, 1.8 mF polarized capacitor with snap‑in mounting is required for standard power and energy storage needs.
• High-temperature assemblies — Suitable for equipment that must operate reliably up to 105°C and require capacitors qualified for extended ripple‑current endurance.
• Chassis or panel-mounted power modules — Snap‑in radial can package provides robust mounting for assemblies where secure mechanical attachment and serviceability are important.

Unique Advantages

• Extended 105°C endurance: Rated to withstand 3000 hours of rated ripple current at 105°C, delivering predictable long-term performance under thermal stress.
• High ripple handling: Clear ripple current ratings at 120 Hz and 100 kHz (3.08 A and 4.62 A respectively) enable selection with defined thermal and ripple budgets.
• Compact snap‑in form factor: One rank smaller case size than the LGU series allows tighter packaging without sacrificing rated voltage or capacitance.
• Wide operating range: −40°C to +105°C supports a broad set of environmental conditions for general-purpose systems.
• RoHS compliance: Meets current RoHS directive requirements for reduced hazardous substances in assemblies.
• Manufacturer pedigree: Manufactured by Nichicon as part of the LGN series, providing consistent series-level electrical and mechanical specifications.

Why Choose LGN2D182MELC40?

LGN2D182MELC40 is positioned for designers seeking a robust, snap‑in aluminum electrolytic capacitor that balances high voltage (200 V), substantial capacitance (1.8 mF), and extended 105°C ripple‑current endurance. Its radial snap‑in package and reduced case size relative to the LGU series make it a practical choice where board or chassis space is constrained.

This part is well suited for general‑purpose electronic assemblies and power modules that require documented endurance at elevated temperature and clear ripple‑current specifications, backed by Nichicon’s LGN series design and RoHS compliance for regulatory consistency.
