LGN2E182MELC50

The LGN2E182MELC50 from Nichicon is a snap‑in terminal, large‑can aluminum electrolytic capacitor offering 1800 µF capacitance at a 250 V rating. Part of the LGN series, this radial can snap‑in component is designed for general‑purpose applications that require high capacitance, high‑temperature endurance and robust ripple handling.

Key value propositions include a 105°C operating range with 3000‑hour endurance at 105°C, industry‑grade ripple current capability at both low and high frequencies, and RoHS compliance for modern production environments.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with a 250 V rated voltage and ±20% tolerance, suitable where substantial energy storage at elevated voltage is required.
• Snap‑in Radial Can Package — Snap‑in terminal type in a radial can package (φ35 × 50 L mm) for secure board mounting and mechanical stability in through‑hole assemblies.
• High‑Temperature Endurance — Rated for −40°C to +105°C with an endurance specification of 3000 hours at 105°C, supporting sustained operation in elevated temperature environments.
• Ripple Current Performance — Low‑frequency ripple current 2.7 A at 120 Hz and high‑frequency ripple current 4.05 A at 100 kHz, enabling effective smoothing and filtering under AC ripple conditions.
• Leakage and Dissipation — Specified leakage current of 2010 µA and a tangent of loss angle (tan δ) of 0.15 (measured at 20°C, 120 Hz), providing predictable dissipation and leakage behavior for design margining.
• Compliance & Packaging — RoHS compliant and supplied in tray packing; the part is in mass production and belongs to Nichicon’s LGN series.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing where high capacitance and a 250 V rating are required for reliable DC link and filtering functions.
• Industrial power supplies — Provides ripple current handling and high‑temperature endurance for long‑running supply modules and control systems.
• High‑temperature environments — Suitable for equipment that must operate continuously at temperatures up to 105°C with extended life (3000 hours at 105°C).

Unique Advantages

• High capacitance at elevated voltage — 1800 µF at 250 V supplies substantial energy density for smoothing and decoupling in compact radial can form factors.
• Designed for sustained high‑temperature duty — 3000‑hour endurance at 105°C reduces the need for over‑specifying components in hot operating environments.
• Dual‑band ripple capability — Rated ripple currents at both 120 Hz and 100 kHz let designers account for low‑frequency and high‑frequency ripple sources with one component.
• Predictable leakage and dissipation — Specified leakage current (2010 µA) and tan δ (0.15 at 20°C/120 Hz) support accurate thermal and power‑loss budgeting in designs.
• Robust snap‑in mounting — Snap‑in terminals in a φ35 × 50 mm can provide mechanical stability for through‑hole assemblies and simpler board handling during assembly.
• RoHS compliant and production ready — Tray packing and mass production status simplify procurement and integration into manufacturing workflows.
