LNX2G272MSEH

The LNX2G272MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series, rated 400 V with a capacitance of 2700 µF (2.7 mF). It is engineered for industrial power electronics where high DC voltage, high ripple current capability, and long operational life are required.

Designed for applications such as industrial power supplies and inverter circuitry, the part combines a screw-terminal radial can package with high ripple handling and an endurance rating for extended service at elevated temperature.

Key Features

• Electrical rating: 400 V nominal rated voltage with 2700 µF (2.7 mF) capacitance and ±20% tolerance.
• High ripple capability: Rated ripple current of 8.1 A at 120 Hz and 11.34 A at 100 kHz, enabling robust smoothing and filtering under heavy AC ripple conditions.
• Long endurance at elevated temperature: Specified for 20,000 hours of operation at +85 °C when subjected to the rated ripple current, supporting extended service life in demanding environments.
• Mounting and package: Screw terminal radial can (can with screw terminals) for secure, low-resistance connections in high-current power assemblies; nominal dimensions L: 9 cm × D: 7.62 cm with a maximum seated height of 3.543 inches.
• Operating range and polarization: Polarized capacitor with an operating temperature range of −25 °C to +85 °C suitable for general-purpose power applications.
• Safety and compliance: Flame-retardant electrolyte is available for applicable types, and the product is RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies (inverter circuitry): Energy smoothing and DC link stabilization where high voltage and high ripple currents are present.
• Extra-high-voltage power circuits: Bulk energy storage and filtering in circuits that require extra-high voltage capability and reliable long-term operation.
• General-purpose power filtering and energy storage: Secure screw-terminal connections and generous capacitance make this capacitor suitable for a variety of power electronics filtering tasks.

Unique Advantages

• Extended ripple-life rating: 20,000 hours at +85 °C under rated ripple current provides predictable long-term performance in continuously stressed applications.
• Measured ripple specification: Explicit ripple current ratings at both low and high frequency (8.1 A at 120 Hz and 11.34 A at 100 kHz) let designers match part selection to system ripple conditions.
• Screw-terminal robustness: Screw terminal radial can package delivers secure, low-impedance connections for high-current installations.
• High-voltage capability: 400 V rating supports extra-high-voltage applications without the need to parallel multiple lower-voltage capacitors.
• Compliance and safety options: RoHS compliance and availability of flame-retardant electrolyte types address regulatory and safety considerations.
