The LNX2L682MSEJBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, providing 6.8 mF capacitance at a 550 V rating. It is designed for high-ripple, extra-high-voltage industrial power applications such as inverter and power-supply circuitry.

Built for robust field use, this polarized radial can offers high ripple-current capability and long endurance at elevated temperature, making it suitable where reliable bulk energy storage and smoothing are required.

Key Features

• Capacitance & Tolerance — 6.8 mF (6800 µF) with tolerance ±20% at 120 Hz, 20°C.
• High Voltage Rating — Rated voltage 550 V for extra-high-voltage power systems.
• Ripple Current Performance — Low-frequency ripple current 19.5 A (120 Hz) and high-frequency ripple current 27.3 A (100 kHz) to support heavy smoothing and ripple handling.
• Endurance at Elevated Temperature — Rated for 5000 hours at +85°C under specified ripple conditions for 500 V and 550 V parts.
• Leakage and Dissipation — Leakage current specified at 5000 µA (after rated-voltage application); tan δ (DF) 0.2 measured at 20°C, 120 Hz.
• Mechanical & Mounting — Screw-terminal radial can (φ90 × 220 mm) for secure bolted connections and robust installation.
• Operating Range & Compliance — Operating temperature −25°C to +85°C; RoHS compliant. Packaged in cardboard for shipping and handling.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy buffering in inverter and converter power stages where high voltage and high ripple capability are required.
• High-Voltage Power Conversion — DC-link and filter applications operating up to 550 V, benefiting from high ripple-current ratings and long endurance.
• Energy Storage & Smoothing — Decoupling and transient energy delivery in heavy-duty industrial equipment and power electronics.

Unique Advantages

• High ripple-current capability: Supports 19.5 A at 120 Hz and 27.3 A at 100 kHz, enabling effective filtering and smoothing in demanding power circuits.
• Extra-high voltage rating: 550 V rating lets designers target high-voltage DC-link and converter topologies without series stacking.
• Long endurance at temperature: Specified 5000 hours at +85°C under rated ripple conditions for 500 V and 550 V parts, supporting sustained operation in hot environments.
• Robust screw-terminal mounting: Radial can with screw terminals and φ90 × 220 mm footprint provides a secure electrical and mechanical connection for high-current installations.
• Measurable loss and leakage characteristics: tan δ = 0.2 (20°C, 120 Hz) and leakage current up to 5000 µA, allowing predictable design margining and thermal management.
• RoHS compliant and production-ready: Mass-production status and RoHS compliance support procurement and regulatory requirements.
