LGN2E102MELB40

The LGN2E102MELB40 from Nichicon is a snap-in terminal, large-can aluminum electrolytic capacitor in the LGN series. It provides 1000 µF capacitance at a 250 V rating with a compact φ30 × 40 mm can and is packaged for tray handling in mass production.

Designed for general-purpose power electronics, this part delivers sustained ripple-current capability and long high-temperature endurance, making it suited for applications that require bulk energy storage and reliable smoothing performance at elevated temperatures.

Key Features

• Capacitance & Rated Voltage — 1000 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• High ripple-current capability — Low-frequency ripple current of 2.2 A (120 Hz) and high-frequency ripple current of 3.3 A (100 kHz) for demanding AC ripple environments.
• High-temperature endurance — Specified lifetime of 3000 hours at 105°C with maintained capacitance, tan δ, and leakage current characteristics after endurance testing.
• Low loss characteristic — Tangent of loss angle (tan δ) rated at 0.15 (measured at 20°C, 120 Hz), supporting efficient energy dissipation in filtering tasks.
• Leakage current — Initial leakage current specified at 1500 µA (measured after voltage application at 20°C), supporting predictable bias behavior.
• Robust operating range — Operating temperature range from −40°C to +105°C for use across a broad set of environmental conditions.
• Snap-in radial can package — φ30 × 40 mm snap-in can (radial) for secure mechanical and electrical mounting in board-level assemblies; tray packing supports volume production handling.
• RoHS compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and decoupling in power electronics where sustained ripple current and thermal endurance are required.
• Power supply energy storage — Provides stored charge and ripple handling in factory and industrial power assemblies designed for continuous operation at elevated temperature.
• Industrial control and equipment — Suitable for general-purpose power circuits in industrial systems that benefit from long life at 105°C and reliable leakage characteristics.

Unique Advantages

• Long high-temperature life: Rated for 3000 hours at 105°C under DC bias plus rated ripple current, ensuring stable capacitance and leakage over extended elevated-temperature use.
• Strong ripple handling: 2.2 A (120 Hz) and 3.3 A (100 kHz) ripple-current ratings help manage both low- and high-frequency ripple in power systems.
• Predictable electrical characteristics: Specified tan δ of 0.15 and controlled leakage current support consistent performance and easier system-level design margins.
• Compact snap-in package: φ30 × 40 mm can with snap-in terminals for reliable board mounting and efficient use of PCB area for large-value electrolytic capacitance.
• Production-ready packaging: Tray packing and mass-production status facilitate procurement and assembly for high-volume manufacturing.
