LGJ2W820MELA20

The LGJ2W820MELA20 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGJ series, designed for high-voltage, general-purpose power applications. It combines a 450 V rated voltage with 82 µF capacitance in a compact, low-profile radial can with snap-in mounting.

Engineered for continuous operation up to 105°C and specified with long endurance, the part targets power-supply smoothing and DC-bus energy storage where high voltage capability, significant ripple handling and durable high-temperature performance are required.

Key Features

• Capacitance & Voltage — 82 µF rated capacitance with 450 V nominal voltage and ±20% tolerance at 120 Hz, 20°C.
• Package & Mounting — Snap-in terminal, radial can package sized 25 mm diameter × 20 mm length for compact chassis integration.
• Thermal & Endurance — Operating temperature range −25°C to +105°C with 3000 hours endurance at 105°C.
• Ripple Current Performance — Low-frequency ripple current 740 mA (120 Hz) and high-frequency ripple capability 1.058 A (50 kHz), supporting a range of switching and line-frequency conditions.
• Electrical Loss & Leakage — Dissipation factor (tan δ) up to 0.20 measured at 20°C, 120 Hz, and leakage current specified at 570 µA.
• Polarized Electrolytic — Polarized construction for conventional DC applications.
• Production & Packing — Mass production status with tray packing for volume assembly processes.

Typical Applications

• Power supply smoothing — Bulk filtering and ripple reduction on high-voltage DC rails, leveraging the 450 V rating and substantial ripple current capacity.
• DC bus energy storage — Local energy reservoir in converters and inverters where compact high-voltage capacitance is required.
• Industrial power electronics — General-purpose use in industrial power modules and switch-mode supplies operating up to 105°C.

Unique Advantages

• High-voltage capability: 450 V rating enables use on elevated DC rails without series stacking.
• Long high-temperature endurance: 3000 hours at 105°C provides durability for sustained elevated-temperature operation.
• Compact low-profile form factor: 25 mm × 20 mm radial can with snap-in terminals conserves board and chassis space while supporting robust mounting.
• Wide-frequency ripple handling: Specified ripple current at both 120 Hz and 50 kHz supports performance across line-frequency and switching environments.
• Controlled dissipation and leakage: tan δ ≤ 0.20 and defined leakage current support predictable loss and standby characteristics in power designs.
• Production-ready packaging: Tray packing and mass-production status simplify procurement and assembly planning.
