LNT2W272MSEG

The LNT2W272MSEG is a screw-terminal aluminum electrolytic capacitor rated at 450 V with 2700 µF (2.7 mF) capacitance and ±20% tolerance. It is a polarized, radial can-style capacitor designed for general-purpose applications that require high-voltage energy storage and filtering.

Key value propositions include a long 5,000-hour rated life at 105°C, robust screw-terminal mounting for secure high-current connections, and measurable ripple-current capability at both low and high frequencies.

Key Features

• Capacitance & Voltage — 2700 µF (2.7 mF) nominal capacitance with a 450 V rated voltage and ±20% tolerance for high-voltage energy storage and smoothing.
• Screw Terminal Package — Radial can with screw terminals (φ63.5 × 130L / L:13 cm × D:6.35 cm) for secure, low-impedance connections in high-current bus architectures.
• Thermal and Lifetime Performance — Rated for operation from −25°C to +105°C with a 5,000-hour endurance at 105°C under rated ripple current conditions.
• Ripple Current Capability — Specified ripple current of 13.8 A at 120 Hz and 19.32 A at 100 kHz for reliable AC stress handling.
• Loss Characteristics — Specified tangent of loss angle (tanδ) of 0.2, enabling predictable dissipation characteristics at 20°C, 120 Hz measurement conditions.
• Polarized, Industrial Packaging — Polarized design in a screw-terminal can; supplied in cardboard packing and available in mass-production quantities.
• RoHS Compliant — Conforms to RoHS requirements as stated in the product information.

Typical Applications

• High-voltage power supplies — Bulk energy storage and smoothing in 450 V class power supply sections where high capacitance and rated voltage are required.
• Industrial power systems — DC bus filtering and ripple reduction using the screw-terminal package for secure, high-current connections.
• Inverter and motor-drive systems — Energy buffering and ripple handling at both low and high frequencies, leveraging the specified ripple current ratings.

Unique Advantages

• High-voltage capability: 450 V rating provides headroom for applications requiring elevated DC bus voltages.
