LGG2P821MELB30

The LGG2P821MELB30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGG series. It provides 820 µF capacitance at a 220 V rating in a compact φ30 × 30 mm can designed for space-conscious power designs.

Designed for general-purpose power filtering and energy storage, this capacitor combines high ripple handling with a 105°C endurance rating, making it suitable for industrial and electronic equipment that requires reliable bulk capacitance in a smaller case size.

Key Features

• Capacitance & voltage — 820 µF nominal capacitance at a 220 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High-temperature endurance — Rated for operation from −40°C to 105°C with a specified life of 2000 hours at 105°C under rated conditions.
• Low-frequency ripple current — 1.85 A (rms) at 120 Hz for effective smoothing in mains-frequency power supplies.
• High-frequency ripple current — 2.775 A at 100 kHz to support switching-power and high-frequency converter applications.
• Loss characteristics — tanδ (DF) = 0.15 (measured at 20°C, 120 Hz), enabling predictable dissipation behavior in circuits.
• Leakage current — Specified leakage current of 1270 µA after standard voltage application.
• Polarized, snap-in package — Radial can with snap-in terminals for secure board mounting and streamlined assembly; supplied in tray packing and available in mass production.
• RoHS compliant — Manufactured in compliance with RoHS directive requirements.

Typical Applications

• Power supply bulk filtering — Provides bulk capacitance and high ripple capability for smoothing DC rails in industrial and commercial power supplies.
• Switching power converters — Handles both low-frequency and high-frequency ripple currents, supporting stable operation of SMPS and converter stages.
• Energy storage for control systems — Offers compact energy storage for hold-up and decoupling in compact electronic and industrial control equipment.

Unique Advantages

• Compact, space-saving footprint — φ30 × 30 mm can provides a smaller-case option within the LGG series suitable for equipment downsizing.
• Wide operating temperature range — −40°C to 105°C rating supports deployment across harsh temperature environments without sacrificing performance.
• Dual-frequency ripple capability — Specified ripple currents at 120 Hz and 100 kHz allow designers to rely on a single capacitor type for both mains-frequency and high-frequency converter demands.
• Long endurance at elevated temperature — 2000 hours at 105°C ensures predictable lifetime behavior in thermally demanding applications.
• Tray packing, mass-production availability — Packaging and production status support volume assembly and consistent supply for manufacturing programs.
