LNX2L272MSEH

The LNX2L272MSEH from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNX series, offering 2700 µF capacitance at a 550 V rating with a ±20% tolerance. Designed for high-voltage, high-ripple applications, it provides a polarized, robust solution in a radial can package with screw terminals.

Targeted at industrial power electronics, the part is suited for inverter circuitry and general-purpose high-voltage systems that require substantial bulk capacitance, elevated ripple handling, and long endurance at elevated temperature. The component is RoHS compliant and available for mass production with cardboard packing.

Key Features

• Capacitance & Voltage: 2700 µF rated capacitance at 550 V, ±20% tolerance (measured at 120 Hz, 20°C).
• High ripple handling: Rated ripple current of 9.4 A at 120 Hz and 13.16 A at 100 kHz to support high-frequency and low-frequency ripple conditions.
• Endurance and reliability: Endurance specified as 5000 hours at 85°C for parts rated at 500 V and 550 V; capacitance change within ±20% and tanδ ≤ 300% of initial specified value after life test.
• Thermal range: Operating temperature range from −25°C to +85°C as specified for the LNX series.
• Leakage current specification: After 5 minutes' application of rated voltage, leakage current is not more than 3√(C·V) µA or 5 mA, whichever is smaller (C: µF, V: V).
• Mechanical package: Radial can with screw terminals (φ76.2 × 150L); robust screw mounting suitable for high-current connections.
• Dielectric loss: Tangent of loss angle (tanδ) specified at 0.2 (measurement frequency: 120 Hz at 20°C).
• Compliance & availability: RoHS compliant and offered in mass production with cardboard packing.

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing for high-voltage supply rails used in industrial equipment.
• Inverter circuitry — DC link and ripple filtering in inverter systems where high voltage and high ripple current capability are required.
• High-voltage, general-purpose systems — Polarized energy storage and filtering functions in systems needing a 550 V rated electrolytic solution.

Unique Advantages

• High-voltage capability: 550 V rating enables use in extra-high-voltage applications without series strings.
• Substantial bulk capacitance: 2700 µF provides significant energy storage in a single polarized capacitor, simplifying BOM and board layout.
• Designed for high ripple: Specified ripple currents at 120 Hz and 100 kHz support both low- and high-frequency filtering requirements.
• Long life at elevated temperature: Endurance defined for 5000 hours at 85°C for 500/550 V parts, helping support industrial duty cycles.
• Robust screw-terminal mounting: Screw terminals facilitate secure, low-resistance connections for high-current paths.
• RoHS compliant and production-ready: Conforms to RoHS and is available in mass production with cardboard packing for scalable deployment.
