LGU2G820MELY

The LGU2G820MELY is a Nichicon LGU-series aluminum electrolytic capacitor in a snap-in terminal, radial can package. It delivers 82 µF of capacitance at a 400 V rated voltage with ±20% tolerance and is designed for general-purpose, high-voltage applications requiring robust ripple handling and long endurance.

Engineered for sustained operation up to 105°C, this part combines high-voltage capability with measurable ripple-current performance and a 3000-hour endurance rating for designs that demand reliable bulk capacitance in a compact, snap-in form factor.

Key Features

• Capacitance & Voltage: 82 µF nominal capacitance rated at 400 V, ±20% tolerance for predictable bulk energy storage and decoupling.
• Ripple Current Performance: Rated ripple current of 640 mA at 120 Hz (low frequency) and 915.2 mA at 50 kHz (high frequency), enabling effective AC ripple dissipation across a broad frequency range.
• High-Temperature Endurance: Endurance rated for 3000 hours at 105°C under rated ripple and DC bias, supporting sustained operation in elevated-temperature environments.
• Leakage Current: Specified leakage current of 540 µA, measured after standard voltage application, for predictable standby behavior.
• Operating Temperature Range: −25°C to +105°C operational range to match the LGU series’ high-temperature standard for 315–450 V parts.
• Package & Mounting: Snap-in radial can design (φ20×30L, L: 3 × D: 2 cm) for robust mechanical retention and straightforward insertion into power assemblies; supplied in tray packing for production handling.
• Regulatory Compliance: RoHS compliant as part of the LGU series.

Typical Applications

• Power supply bulk filtering: Use as a high-voltage bulk capacitor for smoothing and energy storage in 400 V power rails where 82 µF is required.
• Industrial power conversion: Suitable for general-purpose power converter stages that require sustained ripple-current capability and high-temperature endurance.
• Energy smoothing and DC link circuits: Deploy in DC link or intermediate circuits where high-voltage capacitance and reliable ripple dissipation are needed.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage system nodes without derating.
• Measured ripple handling: Explicit low- and high-frequency ripple current specifications (640 mA @120 Hz, 915.2 mA @50 kHz) let engineers match component selection to system ripple conditions.
• Long high-temperature life: 3000 hours endurance at 105°C provides predictable aging characteristics for designs intended to operate in warm environments.
• Compact snap-in form: φ20×30L radial can with snap-in terminals offers a space-efficient, mechanically secure option for through-hole assembly.
• Production-ready packaging: Tray packing and mass-production availability simplify procurement and high-volume assembly workflows.
• RoHS compliant: Conforms to RoHS requirements as indicated for the LGU series.
