LNX2L182MSEH

The LNX2L182MSEH is an aluminum electrolytic capacitor in a screw-terminal can designed for high-voltage, high-ripple applications. With a 1.8 mF capacitance at a 550 V rating and a robust screw-terminal package, it is intended for industrial power systems and general-purpose high-voltage power circuits.

Engineered for sustained operation at elevated temperatures, this part delivers a combination of high ripple-current capability, controlled loss tangent, and long-term endurance for demanding power-electronics environments.

Key Features

• High Voltage Handling — Rated voltage: 550 V, suitable for extra-high-voltage power designs.
• Large Capacitance — 1.8 mF (1800 µF) with ±20% tolerance for bulk energy storage and smoothing.
• High Ripple Current Capability — 6.7 A at 120 Hz (low frequency) and 9.38 A at 100 kHz (high frequency) to support heavy AC ripple in power converters.
• Controlled Dissipation Factor — tan δ = 0.2 at 20°C and 120 Hz for predictable loss performance in design simulations.
• Low Leakage — Specified leakage current of 2980 µA for initial performance characterization.
• Endurance at Elevated Temperature — Rated for 5000 hours at +85°C (specified for parts rated at 500 V and 550 V) to support longer-life applications.
• Screw-Terminal Can Package — Radial can with screw terminals (φ76.2 × 110 mm) and M5 nominal bolt diameter for secure, high-current connections.
• RoHS Compliant — Meets applicable RoHS directives.

Typical Applications

• Industrial Power Supplies (Inverter Circuitry) — Bulk energy storage and ripple filtering in inverter front-ends and industrial converters.
• High-Voltage Power Circuits — Energy smoothing and DC-link buffering where a 550 V rating is required.
• General-Purpose Power Electronics — Applications requiring screw-terminal mounting and robust ripple handling for reliable operation.

Unique Advantages
