LGN2G181MELB25

The LGN2G181MELB25 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It pairs a 180 µF capacitance with a 400 V rated voltage in a compact φ30 × 25 mm can, delivering high-voltage bulk capacitance in a snap-in radial package.

Built for sustained operation at elevated temperature, this part offers 105°C rated performance with 3000 hours endurance and RoHS compliance, making it suitable for production deployments where long-term reliability and compact high-voltage energy storage are required.

Key Features

• Core Electricals — 180 µF nominal capacitance with ±20% tolerance and 400 V rated voltage for high-voltage energy storage and decoupling.
• Loss and Ripple Performance — Specified tanδ of 0.15 (max) at 20°C and 120 Hz; ripple handling of 950 mA at 120 Hz (low frequency) and 1.359 A at 100 kHz (high frequency).
• Leakage Current — Low leakage current specified at 800 µA after rated-voltage application.
• Thermal and Endurance — Rated for operation from −25°C to +105°C with an endurance rating of 3000 hours at 105°C under DC bias plus rated ripple current.
• Package and Mounting — φ30 × 25 mm radial can with snap-in terminals for robust mechanical mounting and easy board installation; packaged in trays for production handling.
• Compliance — RoHS compliant to support regulatory requirements for lead-free assemblies.

Typical Applications

• Power filtering and smoothing — General-purpose high-voltage filtering where 400 V rated capacitance and high ripple capability are required.
• DC link and bulk energy storage — Bulk capacitance for power conversion stages that require sustained performance at elevated temperatures.
• Industrial and commercial power equipment — General-purpose use in equipment that benefits from a compact, high-voltage electrolytic with long endurance.

Unique Advantages

• High-voltage capacity: 400 V rating combined with 180 µF provides substantial bulk energy storage for high-voltage power designs.
• Long elevated-temperature endurance: 3000 hours at 105°C (with DC bias plus rated ripple) supports extended reliability in thermal-stressed environments.
• Dual-frequency ripple capability: Rated ripple currents specified for both 120 Hz and 100 kHz make the part applicable across a range of power-supply switching frequencies.
• Compact snap-in package: φ30 × 25 mm can with snap-in terminals delivers a space-efficient, mechanically secure mounting option for production assemblies.
• Production-ready packaging: Tray packing and mass production status support scalable procurement and assembly workflows.
• Regulatory compliance: RoHS compliance facilitates use in lead-free manufacturing processes.
