LGG2Z122MELA40

The LGG2Z122MELA40 is a snap-in terminal aluminum electrolytic capacitor in a compact radial can (φ25×40 mm) offering 1.2 mF capacitance at 180 V with ±20% tolerance. Designed as part of Nichicon’s LGG series, this 105°C-rated, ultra-smaller-sized capacitor targets general-purpose power applications where high capacitance, reliable ripple handling and reduced board footprint are required.

Key Features

• Snap-in radial can package Secure snap-in terminals for robust PCB mounting in a compact φ25×40 mm can, supplied in tray packing for production handling.
• High capacitance and voltage 1,200 µF nominal capacitance at a 180 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High ripple current capability Rated ripple current of 2.15 A at 120 Hz and 3.225 A at 100 kHz to support smoothing and decoupling under load.
• Wide operating temperature and endurance Rated for −40°C to +105°C operation with a 2,000 hour endurance at 105°C (D.C. bias plus rated ripple current applied).
• Controlled loss and low leakage Dissipation factor tanδ of 0.15 (20°C, 120 Hz) and measured leakage current of 1.39 mA for stable performance.
• Space-optimized LGG series design Part of the LGG family’s ultra-smaller-sized lineup—one rank smaller than LGN—helping equipment downsizing without sacrificing capacitance.
• RoHS compliant and production-ready Conforms to RoHS requirements, available in mass production quantities and packaged in trays.

Typical Applications

• Power supply filtering and smoothing Bulk energy storage and ripple smoothing in general-purpose power supplies that require 180 V working voltage and high capacitance.
• DC bus decoupling Decoupling and stabilization of DC link voltages in control and power conversion modules where high ripple current tolerance is needed.
• General-purpose power electronics Bulk capacitance for industrial and commercial equipment designs seeking a compact, high-voltage electrolytic solution.

Unique Advantages

• Compact, downsizing-friendly footprint: One-rank-smaller case design reduces board area while maintaining 1,200 µF capacitance.
• High ripple endurance: Rated ripple currents at both 120 Hz and 100 kHz enable reliable performance under continuous AC stress.
• High-temperature reliability: 105°C operating capability with a 2,000 hour endurance rating supports sustained thermal operation.
• Measured electrical stability: Low leakage current (1.39 mA) and controlled tanδ (0.15) deliver predictable behavior in filtering applications.
• Production and compliance-ready: RoHS compliant, tray-packed and available in mass production quantities for volume deployment.
