LNT2G272MSEG

The LNT2G272MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, rated 2.7 mF (2700 µF) at 400 V. It is a polarized, radial can style capacitor designed for general-purpose power applications that require high capacitance, high voltage handling and robust ripple performance.

Key value comes from its high-voltage rating, elevated operating temperature capability and long endurance specification—providing reliable bulk energy storage and filtering where secure screw-terminal connections and sustained ripple handling are required.

Key Features

• Capacitance & Voltage: 2.7 mF (2700 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance (at 120 Hz, 20°C).
• Screw Terminal Mounting: Radial can with screw terminals for secure, low-impedance connections suitable for heavy current paths.
• High Temperature Endurance: Rated for operation from −25°C to +105°C with a specified life of 5000 hours at 105°C.
• Ripple Current Capability: Low-frequency ripple 13.1 A (120 Hz) and high-frequency ripple 18.34 A (100 kHz), enabling effective smoothing and decoupling under substantial AC stress.
• Leakage and Dissipation: Specified leakage current 3110 µA and tangent of loss angle (tan δ) 0.2 (measured at 20°C, 120 Hz), providing defined electrical loss characteristics for thermal and performance planning.
• Compact High-Capacitance Package: Size φ63.5 × 110 mm (D × L) with a radial can and screw terminals—packaged for handling and installation in power assemblies. Cardboard packing for shipment.
• Compliance: RoHS compliant and available in mass production.

Typical Applications

• Power supply bulk filtering: High capacitance and 400 V rating make it suitable for bulk energy storage and smoothing in high-voltage DC rails.
• DC‑link and power conversion: Elevated ripple current ratings support use in DC‑link circuits for converters and inverters where sustained AC ripple is present.
• Industrial power systems: Robust 105°C endurance and screw-terminal connections are appropriate for industrial assemblies requiring durable, serviceable capacitors.

Unique Advantages

• High-voltage capability: 400 V rating enables application in higher-voltage DC systems without series arrangements.
• Strong ripple handling: Combined low- and high-frequency ripple current specifications (13.1 A @120 Hz; 18.34 A @100 kHz) reduce heating and extend operational stability under dynamic loads.
• Long-term thermal endurance: Rated 5000 hours at +105°C for designs that require sustained elevated-temperature reliability.
• Secure screw-terminal interface: Screw terminals provide low-resistance, mechanically robust connections for power assemblies and field serviceability.
• Clear electrical characterization: Specified tan δ and leakage current values (tan δ 0.2, leakage 3110 µA) simplify thermal and performance margin calculations.
• RoHS compliant and production-ready: Environmentally compliant and available in mass production for volume deployment.
