LGU1K392MELC

The LGU1K392MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in radial can package. It provides 3,900 µF of capacitance at an 80 V rating with snap-in terminals for robust board mounting.

Designed for general-purpose power applications, the device combines high capacitance, elevated ripple-current capability, and a wide operating temperature range with long endurance at 105°C for reliable bulk energy storage and filtering.

Key Features

• Capacitance & Tolerance — 3,900 µF nominal capacitance with tolerance of ±20% (−20% to +20%) at 120 Hz, 20°C.
• Rated Voltage — 80 V working voltage suitable for medium-voltage power rails and energy-storage roles.
• High Temperature Endurance — Rated for 3,000 hours at 105°C with specified endurance performance after DC bias plus rated ripple current.
• Ripple Current Capability — Low-frequency ripple current 3.07 A at 120 Hz and high-frequency ripple current 3.53 A at 50 kHz (frequency-dependent coefficients apply).
• Leakage and Loss Characteristics — Leakage current specified at 1,670 µA (after rated voltage applied at 20°C); tanδ (loss tangent) max 0.20 measured at 20°C, 120 Hz for the 80 V rating.
• Operating Temperature — −40°C to +105°C operating range for broad environmental compatibility.
• Package & Mounting — Radial snap-in can, size φ35 × 30 mm, tray-packed for production handling and insertion.
• RoHS Compliant — Conforms to RoHS directives referenced in the product documentation.

Typical Applications

• General-purpose power systems — Bulk capacitance and filtering where a robust snap-in radial can is required for power rails and energy buffering.
• Industrial equipment — Use in assemblies that demand long-term operation at elevated temperatures (up to 105°C) with sustained ripple current.
• Power supply modules — Smoothing and decoupling in medium-voltage designs that require 80 V rating and substantial capacitance.

Unique Advantages

• High stored energy per volume — 3,900 µF at 80 V provides substantial bulk capacitance in a φ35 × 30 mm can, reducing the need for multiple smaller capacitors.
• Long endurance at elevated temperature — Specified for 3,000 hours at 105°C under rated ripple conditions, supporting designs with continuous high-temperature operation.
• Robust ripple handling — Rated ripple currents of 3.07 A (120 Hz) and 3.53 A (50 kHz) support demanding AC ripple environments and help maintain system stability.
• Low-frequency loss control — tanδ of 0.20 (at 20°C, 120 Hz) for the 80 V rating helps manage dissipation in power applications.
• Snap-in radial package — Mechanical stability and straightforward board insertion with tray packing for production assembly.
• Regulatory compliance — RoHS-compliant construction to meet environmental requirements.
