LGU2E391MELY

The LGU2E391MELY is a Nichicon LGU-series snap-in aluminum electrolytic capacitor providing 390 µF of capacitance at a 250 V rating. It is engineered for general-purpose electronic applications that require robust ripple endurance and operation up to 105°C.

With snap-in terminals and a compact φ20 × 50 mm can, this component delivers high-frequency and low-frequency ripple performance, controlled loss (tan δ), and RoHS compliance for reliable integration into production designs.

Key Features

• Electrical Performance — 390 µF capacitance with ±20% tolerance and rated voltage of 250 V; tan δ = 0.15 (measured at 20°C, 120 Hz) for controlled loss characteristics.
• Ripple Current Capability — Low-frequency ripple current 1.45 A at 120 Hz and high-frequency ripple current 2.175 A at 50 kHz, supporting mixed-frequency applications.
• Leakage Current — Specified leakage current of 930 µA for predictable leakage behavior after voltage application.
• High-Temperature Endurance — Rated for 3000 hours at 105°C under D.C. bias plus rated ripple current, meeting LGU series endurance criteria.
• Mechanical & Package — Snap-in radial can, size φ20 × 50 mm (D × L), supplied in tray packing and available in mass production status for volume assembly.
• Operating Range & Safety — Operating temperature range −40°C to +105°C and polarization indicated for correct installation.
• Environmental Compliance — RoHS compliant as specified in product data.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance and ripple management where a 250 V, 390 µF snap-in capacitor is specified.
• High-temperature environments — Suitable for designs requiring continuous operation and endurance at up to 105°C, backed by a 3000-hour endurance rating.
• Mixed-frequency power circuits — Supports both low-frequency (120 Hz) and high-frequency (50 kHz) ripple current conditions as defined by the ripple current specifications.

Unique Advantages

• Long-duration ripple endurance: Specified to withstand 3000 hours at 105°C with rated ripple current, enabling longer service life in demanding thermal environments.
• Broad ripple handling: Defined low- and high-frequency ripple current ratings (1.45 A at 120 Hz and 2.175 A at 50 kHz) provide predictable performance across frequencies.
• Compact snap-in packaging: φ20 × 50 mm radial can with snap-in terminals simplifies mechanical mounting for through-hole assemblies.
• Measured dissipation (tan δ): tan δ = 0.15 at 120 Hz, 20°C, offering controlled loss characteristics for AC conditions at the rated voltage.
• Production-ready: Tray-packed and listed as mass production, enabling straightforward procurement and assembly scaling.
• Regulatory compliance: RoHS compliant according to the product data, supporting restricted-substance requirements.
