LGN2Z182MELC35

The LGN2Z182MELC35 is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose power applications. It combines a 1.8 mF capacitance with a 180 V rated voltage and a compact snap‑in radial can package to deliver bulk energy storage and ripple handling in space‑constrained assemblies.

Engineered for elevated operating temperatures, this part is specified for –40°C to +105°C operation and is qualified to withstand 3000 hours of rated ripple current at 105°C, providing predictable endurance and stability in high‑temperature environments. The unit is RoHS compliant and offered in a one‑rank smaller case than the LGU series for denser layouts.

Key Features

• Core Type — Aluminum electrolytic, polarized design in a snap‑in radial can for secure chassis or PCB mounting.
• Electrical Rating — 1.8 mF capacitance at 180 V nominal with ±20% tolerance, suitable for bulk filtering and energy storage roles.
• High‑Temperature Endurance — Rated to operate up to +105°C and specified to withstand 3000 hours of D.C. bias plus rated ripple current at 105°C (endurance criteria: capacitance change within ±20%, tan δ ≤ 200% of initial, leakage current ≤ initial specified value).
• Ripple Current Capability — Rated ripple current of 2.7 A at 120 Hz and 4.05 A at 100 kHz, supporting both low‑frequency and higher‑frequency ripple environments.
• Low‑Temperature Stability — Designed for a category temperature range down to –40°C; for the 160–250 V voltage band the impedance ratio Z(–25°C)/Z(+20°C) is specified (datasheet values apply).
• Compact Package — Smaller case size relative to the LGU series (one rank smaller), dimensions approximately L: 3.5 × D: 3.5 cm and snap‑in mounting for mechanical stability.
• Quality Parameters — Tan δ max 0.15 at 120 Hz, 20°C for the 160–420 V range; shelf life and stability characteristics are defined in the datasheet.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply bulk filtering — Bulk capacitance and rated ripple current make this part suitable for smoothing and energy storage in power supply stages.
• Industrial power equipment — Use in general‑purpose industrial assemblies where high temperature endurance (105°C) and secure snap‑in mounting are required.
• High‑frequency ripple environments — Rated ripple current at 100 kHz supports applications with higher frequency switching ripple components.

Unique Advantages

• High‑temperature reliability: Specified for 3000 hours at 105°C under rated ripple current, delivering controlled capacitance and loss behaviour over long endurance tests.
• Compact footprint: One‑rank smaller case than LGU enables greater design density without sacrificing rated voltage or capacitance.
• Dual‑frequency ripple ratings: Defined ripple current at both 120 Hz and 100 kHz lets designers size the capacitor precisely for low‑ and high‑frequency ripple conditions.
• Robust electrical specifications: 1.8 mF at 180 V with ±20% tolerance and specified tan δ limits supports predictable performance in filtered DC buses.
• Snap‑in mounting: Radial, can‑type snap‑in package provides secure mechanical retention for vertically mounted power assemblies.
• RoHS compliant: Meets current RoHS directives for use in regulated product lines.
