LGN2C182MELB40

The LGN2C182MELB40 is a polarized aluminum electrolytic capacitor in a snap‑in radial can package designed for general-purpose applications. It delivers 1.8 mF capacitance at a 160 V rating with snap‑in mounting and is engineered for elevated‑temperature endurance.

Key value propositions include high ripple current capability, a wide operating temperature range, and a proven 3000‑hour endurance at 105°C for sustained performance in demanding environments.

Key Features

• Electrical Performance — 1.8 mF rated capacitance at 160 V with ±20% tolerance, polarized for DC applications.
• Ripple Current Handling — Rated ripple current of 2.7 A at 120 Hz and 4.05 A at 100 kHz, supporting continuous AC ripple stress.
• Thermal Endurance — Operates from −40 °C to +105 °C and is specified to withstand 3000 hours of rated ripple current at 105 °C.
• Package & Mounting — Radial, can-type snap‑in package offering secure board retention and simple mounting for through‑hole assemblies.
• Compact Series Design — One rank smaller case size compared with the LGU series, enabling reduced board footprint where space is limited.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Size — Body dimensions L: 4 × D: 3 cm (radial can, snap‑in).

Typical Applications

• General‑purpose power circuits — Provides bulk capacitance and ripple handling for circuits requiring a 160 V, 1.8 mF polarized capacitor.
• High‑temperature environments — Suitable where sustained operation up to 105 °C and long endurance under ripple stress are required.
• Through‑hole assemblies — Snap‑in radial can package for reliable mechanical retention and straightforward PCB mounting.

Unique Advantages

• High ripple capability: Rated ripple currents at both low and high frequencies (2.7 A @ 120 Hz, 4.05 A @ 100 kHz) support robust AC stress tolerance.
• Proven thermal endurance: Specified 3000 hours at 105 °C under rated ripple current, delivering predictable long‑term behavior in hot environments.
• Space‑efficient form factor: One rank smaller case size than LGU series helps reduce board footprint without sacrificing capacitance.
• Secure mounting: Snap‑in radial can simplifies assembly and provides strong mechanical retention for through‑hole designs.
• Regulatory compliance: RoHS compliance supports restricted‑substance requirements for modern electronics manufacturing.

Why Choose LGN2C182MELB40?
