LGN2D102MELZ50

The LGN2D102MELZ50 is a snap-in terminal aluminum electrolytic capacitor in Nichicon’s LGN series, offering 1 mF capacitance at a 200 V rating. It is a smaller-sized snap-in can designed for general-purpose use where elevated temperature endurance and reliable ripple handling are required.

This part is specified for operation from −40 °C to 105 °C, designed to withstand 3000 hours of rated ripple current application at 105 °C, and is compliant with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Electrical performance — 1 mF capacitance with ±20% tolerance and a 200 V rated voltage; polarized design for DC bulk and smoothing applications.
• Thermal and reliability — Operating temperature range −40 °C to 105 °C with endurance specified as 3000 hours at 105 °C under D.C. bias plus rated ripple current.
• Ripple current capability — Rated for 2.3 A at 120 Hz (low frequency) and 3.45 A at 100 kHz (high frequency), supporting both low- and high-frequency ripple demands.
• Leakage performance — Leakage current meets the series specification I ≤ 3/√(C) μA (measured after 5 minutes at 20 °C), supporting predictable DC performance.
• Package and mounting — Radial, snap-in can package for secure chassis or board mounting; compact size L: 5 × D: 2.2 cm and one rank smaller case than LGU.
• Environmental compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — 1 mF at 200 V and robust ripple handling make it suitable for smoothing and bulk energy storage in general-purpose circuits.
• High-temperature environments — Rated to 105 °C with 3000-hour ripple endurance for applications exposed to elevated ambient temperatures.
• Snap-in mounting installations — Radial snap-in can provides reliable mechanical retention for chassis- or board-mounted power assemblies where a smaller case size is preferred.

Unique Advantages

• Long high-temperature endurance: Specified to withstand 3000 hours of rated ripple current at 105 °C, supporting extended service life in hot environments.
• Broad ripple frequency coverage: Separate low-frequency and high-frequency ripple current ratings (2.3 A at 120 Hz, 3.45 A at 100 kHz) give designers measurable performance across application spectra.
• Compact, space-saving form factor: Smaller-sized case (one rank smaller than LGU) with L: 5 × D: 2.2 cm helps reduce board or chassis footprint without compromising capacitance.
• Predictable leakage behavior: Leakage current specified by I ≤ 3/√(C) μA after rated-voltage application ensures consistent DC leakage characteristics.
• RoHS compliance: Meets modern environmental requirements, simplifying inclusion in regulated products.
• Robust snap-in mounting: Radial snap-in can design provides mechanical stability for power assemblies and easy installation.
