LGN2Z102MELC25

The LGN2Z102MELC25 is a Nichicon LGN-series snap-in aluminum electrolytic capacitor specified at 1 mF and 180 V. It is a large-can, radial snap-in terminal type designed for general-purpose applications that require sustained ripple endurance and stable operation up to 105 °C.

Engineered for reliability under elevated temperature and ripple conditions, this part offers a compact case size (one rank smaller than LGU) and is RoHS compliant.

Key Features

• Capacitance & Voltage — Rated at 1 mF and 180 V, polarized construction suitable for general-purpose power applications.
• High-temperature endurance — Withstands 3000 hours application of rated ripple current at 105 °C, meeting the LGN series endurance specification.
• Ripple current capability — Rated ripple current of 2.2 A at 120 Hz and 3.3 A at 100 kHz, supporting both low- and high-frequency stress cases.
• Operating range — Specified for operation from −40 °C to 105 °C.
• Package & mounting — Radial, large-can snap-in terminal type for secure board retention; physical size approximately L: 2.5 × D: 3.5 cm with a seated height max of 2.5 cm.
• Tolerance & leakage — Capacitance tolerance of −20% to +20%; leakage current governed by the LGN series specification I ≤ 3√C μA (after 5 minutes at 20 °C).
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Compact case option — One rank smaller case size than LGU for designs where board space or packing density is a consideration.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage where a 1 mF, 180 V snap-in capacitor with high ripple endurance is required.
• Industrial electronics — Power filtering and decoupling in equipment operating across −40 °C to 105 °C ambient ranges.
• Power conversion modules — Input/output filtering in converters where sustained ripple current capability and a snap-in radial can are beneficial.

Unique Advantages

• Long ripple-endurance life — Rated for 3000 hours at 105 °C under rated ripple conditions, providing predictable longevity in high-stress environments.
• Dual-frequency ripple performance — Specified ripple currents at both 120 Hz (2.2 A) and 100 kHz (3.3 A) to support a range of power system frequencies.
• Space-optimized can — One rank smaller than LGU offers a more compact footprint without sacrificing endurance.
• Secure board mounting — Snap-in radial can provides robust mechanical retention for through-hole assemblies.
• Regulatory compliance — RoHS compliance supports use in regulated product lines and helps simplify environmental compliance workflows.
