LGGW6181MELA30

The LGGW6181MELA30 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGG series engineered for compact, high-voltage applications. This 180 µF, 420 V polarized capacitor delivers capacitive energy storage and smoothing in equipment where reduced case size and reliable high-temperature endurance are required.

Designed as an ultra-smaller-sized option within the LGG family, the part is suited to general-purpose power electronics that benefit from a high-voltage rating, snap-in mounting, and a rated lifetime of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 420 V rated voltage, providing high-voltage bulk storage for smoothing and filtering.
• High-temperature Endurance — Rated for 2000 hours at 105°C, enabling sustained operation in elevated-temperature environments.
• Compact Snap-in Package — Snap-in terminal, radial can (φ25 × 30 mm), designed for space-constrained assemblies and easy PCB insertion.
• Ripple Handling — Low-frequency ripple current of 910 mA (120 Hz) and high-frequency ripple current of 1.301 A (100 kHz) for effective ripple filtering across a broad frequency range.
• Leakage & Loss — Leakage current specified at 820 µA; tan δ (loss tangent) max 0.15 measured at 20°C, 120 Hz, supporting predictable performance metrics.
• Operating Range & Robustness — Polarized capacitor with operating temperature range −25°C to +105°C and capacitance tolerance ±20% at 20°C, 120 Hz.
• Regulatory & Production — RoHS compliant and available in tray packing; status: mass production.

Typical Applications

• General-purpose power electronics — Bulk energy storage and smoothing in equipment that requires a compact, high-voltage electrolytic capacitor.
• High-temperature environments — Circuits operating up to 105°C that need sustained endurance (2000 h) and stable performance over time.
• Space-constrained system designs — Equipment downsizing where the LGG series’ ultra-smaller-sized case provides the necessary capacitance and voltage in a reduced footprint.

Unique Advantages

• High-voltage capability: 420 V rating enables use in higher-voltage rails without requiring larger discrete components.
• Compact form factor: φ25 × 30 mm can—one rank smaller than comparable cases in the LGN family—helps reduce board area for tighter system layouts.
• Designed for elevated-temperature reliability: 2000 hours at 105°C endurance provides predictable life performance in demanding thermal conditions.
• Broad ripple performance: Specified ripple current at both low (120 Hz) and high (100 kHz) frequencies supports effective filtering across switching and line-frequency environments.
• Predictable electrical characteristics: Defined leakage current (820 µA) and tan δ (0.15 at 20°C, 120 Hz) for consistent design margin calculations.
• Production-ready supply: RoHS compliant with tray packing and mass production status for volume deployment.
