LGN2E122MELC40

The LGN2E122MELC40 is a snap‑in terminal, large‑can aluminum electrolytic capacitor from Nichicon’s LGN series, specified for general‑purpose applications. It delivers 1.2 mF capacitance at a 250 V rated voltage in a radial, can‑style snap‑in package and is RoHS compliant.

Designed for high temperature endurance, this part is specified to withstand 3000 hours of application of rated ripple current at 105°C, offering reliable performance in demanding thermal environments.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance rated at 250 V for bulk energy storage and decoupling in general‑purpose circuits.
• Snap‑in Radial Can Package — Snap‑in terminal type with a radial can package for secure board retention and robust mechanical mounting.
• High‑Temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C, supporting sustained operation under elevated temperature and ripple stress.
• Ripple Current Performance — Rated ripple current of 2.3 A at 120 Hz and 3.45 A at 100 kHz, enabling effective ripple handling across common power frequencies.
• Wide Operating Range — Operating temperature range from −40 °C to 105 °C to suit a broad set of environmental conditions.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction for predictable electrical behavior in DC circuits.
• Compact LGN Series Design — One rank smaller case size than the LGU series, providing a smaller footprint while maintaining performance.
• Environment — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power — Suitable for general‑purpose power filtering and energy storage where a 250 V, 1.2 mF polarized capacitor is required.
• Industrial Electronics — Used in equipment that requires sustained ripple handling and high‑temperature endurance up to 105 °C.
• Board‑Level Bulk Decoupling — Snap‑in mounting and radial can packaging provide dependable board retention for bulk decoupling roles.

Unique Advantages

• Proven High‑Temperature Reliability: Rated for 3000 hours at 105 °C under applied rated ripple current, giving designers measurable endurance data for thermal stress planning.
• Strong Ripple Handling: Specified ripple current values at both low (120 Hz) and high (100 kHz) frequencies support a range of switching and line conditions.
• Smaller Case Size: One rank smaller than comparable LGU parts, enabling space savings without sacrificing key electrical performance.
• Robust Mounting: Snap‑in terminal and radial can construction provide secure mechanical installation for through‑hole board designs.
• Wide Temperature Range: −40 °C to 105 °C operating range supports deployment in environments with significant thermal variation.
• Regulatory Compliance: RoHS compliance supports use in regions and designs that require restriction of hazardous substances.
