LGG2E391MELZ30

The LGG2E391MELZ30 is a snap-in terminal type aluminum electrolytic capacitor from Nichicon’s LGG series, offering 390 µF capacitance at a 250 V rating in a compact φ22 × 30 mm can. Designed for general-purpose use, it supports equipment downsizing while providing robust performance for power systems that require high ripple handling and elevated-temperature endurance.

Key Features

• Capacitance and Voltage: 390 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, suitable for bulk energy storage in mid-voltage circuits.
• High ripple capability: Low-frequency ripple current rated at 1.2 A (120 Hz) and high-frequency ripple current rated at 1.8 A (100 kHz), supporting demanding AC ripple conditions.
• High-temperature endurance: Rated for operation from –40°C to +105°C with an endurance of 2000 hours at 105°C under DC bias plus rated ripple current.
• Electrical characteristics: Loss tangent (tan δ) specified at 0.15 (measured at 20°C, 120 Hz) and a measured leakage current of 930 µA.
• Package and mounting: Snap-in terminal, radial can (snap-in) construction in a compact φ22 × 30 mm case for board-mounted power assemblies.
• Compliance and availability: RoHS compliant, tray packed, and listed as mass production status.

Typical Applications

• Power supply filtering: Bulk smoothing and ripple suppression in mid-voltage power supplies where a 250 V rating and high ripple capability are required.
• Industrial equipment: Energy storage and decoupling in industrial control and power electronics that must withstand elevated operating temperatures up to 105°C.
• Equipment downsizing: Compact snap-in form factor suited to designs that prioritize reduced component footprint without sacrificing capacitance.

Unique Advantages

• Compact, high-capacitance format: 390 µF in a φ22 × 30 mm can provides substantial capacitance for its size, supporting smaller overall equipment designs.
• Robust ripple handling: Rated ripple currents at both low and high frequencies enable reliable operation in applications with significant AC content on the DC bus.
• Elevated-temperature reliability: 2000-hour endurance at 105°C ensures stable performance in high-temperature environments and long-term thermal stress.
• Practical board mounting: Snap-in terminals simplify PCB assembly for radial can installations and secure mechanical retention.
• Regulatory compliance: RoHS compliance supports use in regulated markets and reduces material-related procurement concerns.
• Production-ready packaging: Tray packing and mass production status streamline procurement and volume assembly planning.
