LGU2P391MELZ

The LGU2P391MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series. It delivers 390 µF capacitance at a 220 V rating in a compact φ22 × 35 mm can designed for snap‑in board mounting.

Engineered for general‑purpose power applications, this capacitor combines high ripple‑current capability and long endurance at elevated temperature, offering reliable smoothing and ripple handling in circuits that require sustained performance up to 105°C.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance, suitable where higher-voltage bulk capacitance is required.
• High Ripple Current Capability — Low‑frequency ripple current of 1.4 A (120 Hz) and high‑frequency ripple current of 2.1 A (50 kHz), enabling sustained ripple handling across a range of frequencies.
• Elevated‑Temperature Endurance — Rated for operation from −40°C to +105°C with a specified life of 3000 hours at 105°C under rated ripple conditions.
• Electrical Loss and Leakage — Low dissipation factor (tan δ = 0.15 measured at 20°C, 120 Hz) and a specified leakage current of 870 µA for predictable performance in power circuits.
• Snap‑In Package — Radial, snap‑in can (φ22 × 35 mm) for secure board retention and tray packing for production handling.
• RoHS Compliant — Built to meet RoHS requirements for reduced hazardous substances.

Typical Applications

• General‑purpose power circuitry — Provides bulk capacitance for circuits that require 390 µF at 220 V with snap‑in mounting for reliable board install.
• AC/DC filtering and ripple suppression — Supports sustained ripple currents (1.4 A @120 Hz, 2.1 A @50 kHz) for smoothing and ripple reduction in power conversion stages.
• High‑temperature endurance designs — Suitable where continuous operation at elevated temperatures is required, backed by a 3000‑hour rating at 105°C.

Unique Advantages

• Designed for sustained ripple — Specified low‑ and high‑frequency ripple ratings translate to reliable performance in applications with significant AC content on the DC rail.
• Long life at high temperature — 3000 hours endurance at 105°C provides predictable aging characteristics for designs that operate hot or require long-term reliability.
• Compact snap‑in form factor — φ22 × 35 mm can with snap‑in terminals simplifies mechanical retention and assembly for panel or chassis mounted power modules.
• Measurable electrical stability — Low tan δ (0.15 at 20°C, 120 Hz) and specified leakage current support stable impedance and loss characteristics in power systems.
• Production‑ready packaging — Tray packing and mass‑production status help streamline procurement and assembly for volume builds.
