LNT2V272MSEG

The LNT2V272MSEG is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, specified at 2700 µF and 350 V with polarized terminals. It is designed for general-purpose power applications that require high ripple current handling and long operational life at elevated temperatures.

Key value propositions include a 105°C rated temperature capability, a 5,000-hour load life at 105°C, robust ripple-current performance, and RoHS compliance—making it suitable where reliable bulk energy storage and smoothing are required in industrial power systems and power conversion equipment.

Key Features

• Capacitance & Voltage: 2700 µF capacitance rated for 350 V, providing substantial bulk storage for high-voltage power rails.
• High Ripple Current: Rated ripple current of 12.7 A at 120 Hz and 17.78 A at 100 kHz to support demanding AC ripple conditions in power supplies and converters.
• Thermal and Endurance Performance: Operating temperature range of −25 °C to +105 °C with a specified load life of 5,000 hours at 105 °C when subjected to rated ripple current and DC bias.
• Mechanical & Mounting: Screw terminal radial can package with screw terminals for secure electrical and mechanical connections in high-current installations.
• Tolerance & Polarization: Capacitance tolerance of ±20% and polarized construction for correct orientation in DC circuits.
• Leakage Current Specification: Leakage current meets the datasheet limit (after 5 minutes’ application of rated voltage, leakage current not more than the specified formula or 5 mA, whichever is smaller).
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Package Dimensions: Physical size L: 10 × D: 6.35 cm and radial can with screw terminals for φ35 and larger form factors as defined in the LNT series documentation.

Typical Applications

• Power supply bulk filtering: Bulk energy storage and smoothing on high-voltage DC rails where 350 V rating and high ripple current capability reduce voltage fluctuation.
• DC-link capacitors for power converters: Use in inverter and converter DC-link stages where elevated ripple current and 105 °C operation are required.
• Industrial power equipment: Energy buffering and ripple suppression in industrial drives, UPS systems, and power-conditioning equipment.

Unique Advantages

• High-voltage capability: 350 V rating enables use on higher-voltage DC rails without series stacking.
• Strong ripple current handling: Specified ripple currents at both low and high frequencies support designers addressing switching and mains-frequency ripple sources.
• Extended thermal endurance: 5,000-hour load life at 105 °C provides predictable aging and replacement intervals for high-temperature installations.
• Screw-terminal reliability: Robust screw-terminal connections improve mechanical retention and current-carrying capacity in heavy-current assemblies.
• Clear specification limits: Defined leakage current and tolerance figures allow accurate power-loss and tolerance budgeting in design verification.
• RoHS compliance: Meets environmental directive requirements for reduced hazardous substances.
