LGG2P391MELZ30

The LGG2P391MELZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGG series. It offers 390 µF capacitance at a 220 V rating in a compact φ22 × 30 mm can designed for equipment downsizing.

Engineered for general-purpose power electronics, the device combines high-temperature endurance (–40°C to 105°C) with defined ripple capability and low leakage, making it suitable for designs that require a durable, compact bulk capacitor solution.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 220 V rated voltage and ±20% capacitance tolerance at 20°C, 120 Hz.
• High-temperature Endurance — Rated for operation from –40°C to 105°C with a 2000-hour endurance specification at 105°C.
• Ripple Current Performance — Supports 1.34 A at 120 Hz (low frequency) and 2.01 A at 100 kHz (high frequency), enabling effective handling of AC ripple in powered circuits.
• Leakage and Loss — Leakage current specified at 870 µA and tanδ (dissipation factor) of 0.15 measured at 20°C, 120 Hz for controlled losses and standby drain.
• Snap-In Radial Can Package — φ22 × 30 mm snap-in terminal construction for secure PCB mounting and tray packing for production handling.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• General-Purpose Power Electronics — Bulk energy storage and smoothing in equipment that requires a compact, 220 V electrolytic capacitor.
• Industrial and Commercial Equipment — Suited for designs where a smaller case size and 105°C endurance support compact power assemblies.
• Board-Level Power Modules — Snap-in radial package offers reliable PCB retention for power supply and converter assemblies.

Unique Advantages

• Compact form factor: One rank smaller case size compared to the LGN series, supporting equipment downsizing without sacrificing capacitance.
• High-temperature reliability: 2000 hours of rated-life endurance at 105°C, enabling sustained performance in elevated-temperature environments.
• Robust ripple handling: Defined low- and high-frequency ripple current ratings (1.34 A @120 Hz, 2.01 A @100 kHz) help manage AC stress in power circuits.
• Controlled leakage and dissipation: Low leakage current (870 µA) and a tanδ of 0.15 (20°C, 120 Hz) support predictable system behavior and thermal management.
• Snap-in mounting and tray packing: Snap-in terminals for secure PCB installation and tray packing for efficient handling in production environments.
• Regulatory compliance: RoHS-compliant construction for environmentally conscious designs.
