LGN2H181MELB35

The LGN2H181MELB35 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 180 µF at a 500 V rating in a compact radial can snap‑in package and is manufactured by Nichicon.

Key value propositions include high‑temperature endurance (withstanding 3000 hours of rated ripple current at 105°C), robust ripple current capability, and RoHS compliance for environmentally conscious designs.

Key Features

• Electrical Performance — 180 µF capacitance at a 500 V rated voltage with ±20% tolerance; polarized for DC bulk storage and smoothing.
• High‑Temperature Endurance — Endurance rating of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current (per datasheet).
• Ripple Current Capability — Rated ripple current of 900 mA at 120 Hz and 1.287 A at 100 kHz to handle AC ripple in power circuits.
• Compact Snap‑in Package — Radial, can‑style snap‑in mounting for secure mechanical retention; one rank smaller case size than the LGU series to save PCB space.
• Operating Range — Specified operating temperature range of −25°C to +105°C for sustained elevated‑temperature operation.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Compact footprint with size L: 3.5 × D: 3 cm to aid space‑constrained layouts.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple suppression in general‑purpose AC/DC and DC/DC power supplies, using its rated ripple current and high voltage capability.
• Industrial equipment — Energy storage and decoupling in industrial power modules where high operating temperature and endurance are required.
• Commercial electronics — General‑purpose DC bulk and filtering duties in commercial systems that require a high‑voltage, high‑temperature capacitor.

Unique Advantages

• Long high‑temperature life — 3000‑hour endurance at 105°C under rated ripple provides predictable aging behavior for extended service in hot environments.
• High voltage handling — 500 V rating enables use in higher‑voltage DC link and bulk energy applications without uprating multiple lower‑voltage parts.
• Strong ripple performance — Explicit ripple current ratings at 120 Hz and 100 kHz support a range of switching and line‑frequency stress conditions.
• Space‑saving snap‑in package — Smaller case size than the LGU series and a radial snap‑in mounting style simplify PCB layout and mechanical retention for compact systems.
• Regulatory alignment — RoHS compliance supports environmentally regulated product designs and supply chains.
