LGX2E681MELC25

The LGX2E681MELC25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGX series, offering 680 µF capacitance at a 250 V rating. Designed for general-purpose power electronics, it combines a compact radial can snap-in package with long-life performance targeted at rectifier circuits in general inverters and switching power supplies.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 250 V suitable for higher-voltage power sections.
• High-temperature Long Life — Rated for 5000 hours of endurance at 105°C, providing predictable lifetime behavior under elevated operating temperatures.
• Robust Ripple Handling — Low-frequency ripple current of 1.91 A (120 Hz) and high-frequency ripple current of 2.865 A (50 kHz) for sustained AC stress in power conversion applications.
• Controlled Loss and Leakage — Tangent of loss angle (tan δ) specified at 0.15 (20°C, 120 Hz) and leakage current specified at 1230 µA to help define AC dissipation and DC leakage limits.
• Snap-In Radial Can Package — φ35 × 25 mm (D × L) metal can with snap-in terminals for secure PCB mounting and tray packing for production handling.
• Operating Range and Compliance — Operating temperature range −25°C to +105°C and RoHS-compliant construction.

Typical Applications

• Switching Power Supplies — Suited for energy storage and ripple endurance requirements in switching regulator output stages and bulk filtering.
• General Inverter Rectifier Circuits — Recommended for rectifier circuits in general inverter designs where 250 V rated capacitance and long life are required.
• General-Purpose Power Electronics — Appropriate for power system designs needing a compact, long-life snap-in electrolytic capacitor with defined ripple and leakage characteristics.

Unique Advantages

• Long operational life at high temperature: 5000 hours at 105°C ensures predictable endurance for sustained thermal environments.
• High ripple current capability: Specified ripple currents of 1.91 A (120 Hz) and 2.865 A (50 kHz) support continuous AC stress in power conversion circuits.
• Low dissipation factor: tan δ of 0.15 (20°C, 120 Hz) gives a clear metric for AC loss and thermal planning.
• Compact snap-in form factor: φ35 × 25 mm radial can with snap-in terminals simplifies PCB mounting and mechanical retention in power assemblies.
• RoHS compliant and mass-produced: Environmentally compliant construction and mass production status support volume deployment and procurement stability.
