LGW2E102MELB40

The LGW2E102MELB40 is a Nichicon LGW series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package designed for general‑purpose power applications. It delivers 1000 µF at a rated voltage of 250 V with a compact φ30 × 40 mm form factor and tray packing for production workflows.

Engineered for high ripple environments, this capacitor supports both low‑ and high‑frequency ripple current, offers extended endurance at elevated temperatures, and is RoHS compliant—making it suitable for demanding power filtering and smoothing roles in industrial and electronic equipment.

Key Features

• Capacitance and Voltage: 1000 µF rated capacitance at 250 V for bulk energy storage and smoothing in power circuits.
• High Ripple Current Handling: Rated for 3.3 A at 120 Hz (low frequency) and 4.95 A at 50 kHz (high frequency), supporting demanding ripple conditions.
• 105 °C Endurance: Specified lifetime of 3000 hours at 105 °C with rated ripple current applied, providing sustained performance under elevated temperatures.
• Leakage and Tolerance: Leakage current listed at 1500 µA and capacitance tolerance of ±20% (at 120 Hz, 20 °C) for predictable electrical behavior.
• Snap‑In Mounting and Can Package: Snap‑in terminal, radial can construction for secure panel or PCB mounting and robust mechanical retention.
• Environmental Compliance: RoHS compliant, meeting current restrictives for lead‑free applications.
• Packaging and Production: Tray packing format and mass production status to support volume manufacturing and assembly processes.

Typical Applications

• Power supply smoothing: Bulk filtering and ripple reduction in industrial and commercial power supplies where high ripple current capability is required.
• Inverters and motor drives: Energy buffering and decoupling in power conversion and motor control circuits subjected to high-frequency switching ripple.
• UPS and energy storage systems: Bulk capacitance for short-term energy hold-up and stabilization under elevated operating temperatures.

Unique Advantages

• Designed for high ripple environments: Explicit low‑ and high‑frequency ripple ratings (3.3 A at 120 Hz, 4.95 A at 50 kHz) allow designers to match component performance to switching and line conditions.
• Extended high‑temperature endurance: 3000 hours at 105 °C under rated ripple current reduces the need for frequent replacements in hot operating environments.
• Robust snap‑in format: Radial can with snap‑in terminals offers secure mechanical mounting for assemblies exposed to vibration or handling.
• Predictable electrical characteristics: Specified leakage current and ±20% capacitance tolerance support predictable system behavior and easier validation.
• Production‑ready packaging: Tray packing and mass production availability streamline procurement and assembly for volume manufacturing.
• Manufacturer backing: Part of Nichicon’s LGW series, providing consistent specification traceability within the series.
