LGG2C182MELB40

The LGG2C182MELB40 is an aluminum electrolytic capacitor from Nichicon's LGG series, designed as a snap-in terminal type in an ultra-smaller-sized package. It provides 1.8 mF capacitance at a 160 V rating with RoHS compliance and is intended for general-purpose use where compact size, high-temperature endurance and reliable bulk capacitance are required.

With a rated operating range down to −40°C and up to 105°C and defined endurance at elevated temperature, this part is suited for equipment requiring stable bulk energy storage and ripple-handling in commercial and industrial applications.

Key Features

• Capacitance & Voltage — 1.8 mF nominal capacitance rated at 160 V, providing substantial bulk energy storage in a compact package.
• High-Temperature Endurance — Rated for operation from −40°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Specified ripple handling of 2.7 A at 120 Hz and 4.05 A at 100 kHz, enabling effective smoothing under varying switching and line conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) specified with a maximum of 0.15 at rated conditions (120 Hz, 20°C) for the 160 V range.
• Leakage Current Specification — Leakage current defined by I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20°C, allowing predictable leakage behavior for design margin calculations.
• Package & Mounting — Snap-in radial can with a compact footprint (approximately 4 × 3 cm), optimized for board-mounted power modules and assemblies where reduced case size is required.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing — Bulk filtering and energy storage in commercial and industrial power supplies, leveraging 1.8 mF at 160 V and rated ripple current specifications.
• DC link / energy buffering — Local energy buffering in systems that require sustained capacitance and defined endurance at elevated temperatures.
• Industrial electronics — General-purpose use in industrial control and power conversion equipment where compact high-voltage capacitors are needed.

Unique Advantages

• Compact ultra-smaller-sized package — One rank smaller case size supports equipment downsizing without sacrificing bulk capacitance at 160 V.
• High-temperature reliability — 2000-hour endurance at 105°C provides predictable long-term performance in thermally demanding environments.
• Well-defined ripple performance — Separate ripple current ratings at low and high frequency (120 Hz / 100 kHz) help designers size capacitors for specific switching regimes.
• Predictable leakage behavior — Leakage current limited by the I ≤ 3√CV formula enables accurate leakage budgeting in power designs.
• RoHS-compliant — Meets applicable RoHS directives for use in regulated markets and products.
• Snap-in mounting for secure installation — Radial snap-in can simplifies mechanical retention in PCB assemblies and power modules.
