LGG2G181MELA25

The LGG2G181MELA25 is a Nichicon LGG series snap‑in terminal aluminum electrolytic capacitor rated at 400 V with 180 µF capacitance and ±20% tolerance. Designed as a compact, snap‑in radial can, this part targets general‑purpose applications where high voltage capability, durable endurance, and compact sizing are required.

Key performance attributes include a low loss tangent (tan δ = 0.15 at 20°C, 120 Hz), rated ripple current of 730 mA at 120 Hz and 1.044 A at 100 kHz, and a 2000‑hour endurance at 105°C. The capacitor is RoHS compliant and supplied in tray packing for mass production use.

Key Features

• Voltage and Capacitance — 400 V rated voltage with 180 µF capacitance and ±20% tolerance for stable bulk energy storage at high DC potential.
• Low Loss Tangent — tan δ of 0.15 (max) measured at 20°C and 120 Hz, supporting efficient operation with reduced dielectric losses.
• High Ripple Current Capability — 730 mA at 120 Hz (low frequency) and 1.044 A at 100 kHz (high frequency), enabling handling of significant AC ripple under DC bias conditions.
• Endurance and Temperature Range — Rated for 2000 hours at 105°C with operating temperature range of −25°C to +105°C, providing long life under elevated temperature stress.
• Leakage Current — Specified leakage current of 800 µA, suitable for applications where controlled leakage is required after voltage application.
• Compact Snap‑In Package — φ25 × 25 mm radial can with snap‑in terminals for secure board mounting and ease of assembly; supplied in tray packing for production environments.
• Series Advantages — Part of the Nichicon LGG family, designed to support equipment downsizing through reduced case size compared to predecessor series.

Typical Applications

• General Purpose Electronics — Use where a polarized 400 V, 180 µF aluminum electrolytic capacitor is required for general‑purpose circuit needs.
• Compact Equipment Designs — The smaller LGG series case size supports designs targeting reduced enclosure volume and optimized board layout.
• Production Assemblies — Tray packing and snap‑in mounting make this part suitable for mass production and reliable assembly processes.

Unique Advantages

• High Voltage Capability: 400 V rating provides headroom for higher DC applications while maintaining a compact footprint.
• Strong Ripple Handling: Dual ripple specifications (730 mA at 120 Hz and 1.044 A at 100 kHz) allow predictable performance across low and high frequency ripple environments.
• Durable Endurance: 2000 hours at 105°C ensures sustained performance for extended high‑temperature operation.
• Efficient Dielectric Performance: Low tan δ (0.15 at 20°C/120 Hz) reduces dissipation and supports thermal management in constrained designs.
• Compact Snap‑In Form Factor: φ25 × 25 mm radial can with snap‑in terminals simplifies mounting and helps minimize board area compared with larger case options.
• RoHS Compliant: Meets RoHS directive requirements for lead‑free manufacturing environments.
