LNX2L272MSEHBB

The LNX2L272MSEHBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for extra-high voltage, high-ripple applications. With a rated capacitance of 2.7 mF (2700 µF) and a 550 V rating, it is intended for industrial power supply uses such as inverter circuitry where high ripple current and robust mechanical connections are required.

This part combines high ripple-handling capability, a wide operating temperature range of −25 °C to +85 °C, and RoHS compliance, delivering a reliable energy-storage solution for sustained operation in demanding industrial environments.

Key Features

• Capacitance & Voltage — Rated at 2.7 mF (2700 µF) and 550 V, providing significant bulk energy storage for high-voltage DC circuits.
• Screw-terminal package — Radial can with screw terminals for secure, high-current connections and straightforward mounting in industrial assemblies.
• High ripple current capability — Rated ripple current of 9.4 A at 120 Hz and 13.16 A at 100 kHz, suitable for high-ripple DC-link and inverter applications.
• Endurance at elevated temperature — Designed for 5000 hours at +85 °C under specified conditions for parts rated at 550 V, supporting longer operational life in high-stress environments.
• Operating range and tolerance — Operates from −25 °C to +85 °C with capacitance tolerance of ±20% (at 120 Hz, 20 °C); polarized device.
• Leakage current specification — After 5 minutes at rated voltage, leakage current is not more than 3√(C·V) µA or 5 mA, whichever is smaller (measured at 20 °C), per datasheet guidance.
• Mechanical dimensions — Length × diameter: 15 × 7.62 cm with a maximum seated height of 5.906 inches, enabling planning for cabinet and bracket mounting.
• Compliance and safety options — RoHS compliant; flame-retardant electrolyte versions are available for applications requiring that option.

Typical Applications

• Industrial power supplies — Energy storage and smoothing for inverter and high-voltage power supply stages where sustained ripple current and voltage rating are required.
• Inverter circuitry — DC-link and filtering applications in motor drives and power conversion equipment that demand extra-high voltage capability and robust connections.
• High-ripple, high-voltage filtering — Bulk filtering in systems exposed to high ripple currents and sustained thermal loads up to +85 °C.

Unique Advantages

• Extra-high voltage capability: A 550 V rating enables use in higher-voltage industrial DC systems without series stacking.
• Designed for high ripple: Specified ripple current values at both 120 Hz and 100 kHz support designs with significant AC ripple components.
• Durability under load: Endurance rating of 5000 hours at +85 °C for 550 V parts provides predictable life performance under rated ripple conditions.
• Robust, serviceable termination: Screw-terminal radial can package simplifies secure connections and replacement in the field.
• Regulatory alignment and options: RoHS compliance and availability of flame-retardant electrolyte types address environmental and safety considerations.
• Clear electrical limits: Leakage current and tolerance are specified for straightforward design verification and component selection.
