LNT2W272MSEGBN

The LNT2W272MSEGBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering 2.7 mF (2700 µF) capacitance at a rated voltage of 450 V. Built for general-purpose power applications, it provides high ripple-handling capability and long-term endurance for demanding DC link and power-conditioning functions.

Designed for robust electrical connections and long service life, this radial can (screw terminals) is specified for operation from −25°C to +105°C with a load life of 5000 hours at 105°C.

Key Features

• High Capacitance: 2.7 mF (2700 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C for energy storage and smoothing.
• High Voltage Rating: Rated at 450 V to support high-voltage DC bus and power conversion circuits.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low-inductance connections for high-current applications.
• Robust Ripple Performance: Low-frequency ripple current 13.8 A at 120 Hz and high-frequency ripple current 19.32 A at 100 kHz, enabling effective ripple filtering across a wide frequency range.
• Loss Tangent (tan δ): tanδ = 0.2 (measured at 20°C, 120 Hz), supporting predictable dissipation characteristics.
• Leakage Current: Specified leakage current of 3300 µA after 5 minutes at rated voltage (20°C), consistent with electrolytic performance expectations.
• High-Temperature Endurance: Rated life of 5000 hours at 105°C when subjected to rated ripple current and DC bias; meets endurance criteria for long-term operation.
• Mechanical Size: Package dimension φ63.5 × 130L (L: 13 cm × D: 6.35 cm) for installation planning and bracket mounting.
• RoHS Compliant: Conforms to RoHS requirements for regulatory compliance.

Typical Applications

• Power conversion: Filtering and energy storage on DC link circuits and power supplies where high voltage and ripple capability are required.
• Industrial power equipment: Bulk capacitance and smoothing in drives, converters, and other industrial power-conditioning systems.
• High-voltage assemblies: Use in systems that require radial screw-terminal mounting for secure high-current connections.

Unique Advantages

• High-voltage, high-capacitance combination: 450 V rating paired with 2700 µF provides substantial stored energy for DC bus and smoothing tasks.
• Broad ripple performance: Separate low- and high-frequency ripple ratings (13.8 A at 120 Hz and 19.32 A at 100 kHz) support effective filtering across frequency ranges.
• Screw-terminal reliability: Robust mechanical and electrical terminations reduce contact resistance and ease field wiring for heavy-current applications.
• Long rated life at elevated temperature: 5000-hour endurance at 105°C under rated conditions helps reduce maintenance and replacement frequency.
• Clear electrical parameters: Defined tanδ, leakage current, and tolerance permit predictable thermal and electrical design margins.
• Regulatory compliance: RoHS status simplifies use in regulated markets.
