LGX2E681MELB35

The LGX2E681MELB35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX long‑life series. It delivers 680 µF capacitance at a 250 V rating in a smaller-sized snap‑in radial can intended for power electronics assemblies.

Engineered for rectifier circuits in general inverters and switching power supplies, this capacitor offers extended operation at elevated temperature with long‑life assurance under rated ripple current conditions.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 250 V, suitable for bulk energy storage and smoothing in power circuits.
• High‑temperature long life — Designed to withstand 5000 hours of rated ripple current at 105°C as part of the LGX long‑life series.
• Ripple current performance — Rated ripple current of 2.06 A at 120 Hz and 3.09 A at 50 kHz for robust rectifier and filter operation.
• Operating temperature range — Specified for −25°C to +105°C to support a wide range of industrial operating environments.
• Mounting and package — Snap‑in terminal, radial can (snap‑in) in a smaller-sized footprint (L: 3.5 × D: 3 cm) for dense PCB power sections.
• Tolerance & polarity — Polarized capacitor with tolerance of −20% to +20%.
• Endurance and reliability — After 5000 hours at 105°C with DC bias plus rated ripple, capacitance remains within ±20%, tan δ stays within specified limits, and leakage current remains at or below initial specification.
• RoHS compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General inverters — Used in rectifier and smoothing stages where sustained ripple handling and elevated‑temperature endurance are required.
• Switching power supplies — Provides bulk capacitance and ripple current capability for DC link and output filter sections.
• General‑purpose power electronics — Suited for power conversion and energy‑storage roles in industrial and commercial equipment.

Unique Advantages

• Long operational life at 105°C — 5000‑hour endurance under rated ripple current provides predictable aging behavior for high‑temperature designs.
• Measured ripple capability — Explicit ripple current ratings at 120 Hz and 50 kHz enable designers to match capacitor selection to expected operating frequencies.
• Compact snap‑in packaging — Smaller-sized radial can with snap‑in terminals supports higher board density and simplified mounting in power assemblies.
• Stable electrical characteristics after endurance — Capacitance change and dissipation factor limits after 5000 hours support predictable performance over product lifetime.
• RoHS‑compliant construction — Meets current RoHS directive requirements for restricted substances.
