LGN2G101MELY30

The LGN2G101MELY30 is a Nichicon aluminum electrolytic capacitor in a snap‑in terminal, radial can configuration designed for general‑purpose applications. It provides 100 µF capacitance at a 400 V rated voltage in a smaller-sized snap‑in package (one rank smaller than LGU).

Engineered for elevated-temperature operation, this part is specified for operation up to 105°C and is rated to withstand 3000 hours of applied rated ripple current at 105°C, offering reliable high-voltage bulk capacitance where extended endurance is required.

Key Features

• Electrical Performance — 100 µF capacitance with a 400 V rated voltage and ±20% tolerance, providing high-voltage bulk energy storage in a compact package.
• High‑Temperature Endurance — Specified endurance of 3000 hours at 105°C when DC bias plus rated ripple current is applied; capacitance change remains within ±20% after endurance testing.
• Ripple Current Capability — Rated ripple currents of 680 mA at 120 Hz and 972.4 mA at 100 kHz, supporting continuous ripple handling under rated conditions.
• Package & Mounting — Snap‑in, radial can package for secure board mounting; physical dimensions L: 3 × D: 2 cm and a maximum seated height of 1.181 inch.
• Temperature Range — Operating temperature range from –25°C to 105°C for this voltage class (400 V rating).
• Polarized Design — Polar capacitor suitable for DC applications that require a polarized electrolytic solution.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power applications — Suitable where 100 µF at 400 V polarized bulk capacitance is required in a snap‑in package.
• High‑temperature environments — Designed for equipment that subjects capacitors to elevated ambient temperatures up to 105°C while maintaining rated ripple current.
• PCB-mounted radial designs — Snap‑in radial can format for secure mounting in power assemblies and general electronic equipment.

Unique Advantages

• High‑voltage capability: 400 V rating provides designers with high DC voltage headroom in a single capacitor.
• Compact snap‑in form factor: One rank smaller case than LGU and compact L: 3 × D: 2 cm dimensions reduce board space for high-voltage bulk capacitance.
• Extended high‑temperature endurance: 3000 hours at 105°C under rated ripple and DC bias delivers predictable aging and long service intervals.
• Robust ripple handling: Specified ripple currents at both 120 Hz and 100 kHz support a range of power conversion and filtering scenarios.
• RoHS compliance: Meets current RoHS directive requirements for restricted substances.
