LNT2W272MSEHBN

The LNT2W272MSEHBN is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power electronics that require high voltage handling and robust ripple current performance. It combines a 2.7 mF (2700 µF) capacitance with a 450 V rated voltage in a radial can with screw terminals for secure electrical and mechanical connections.

Targeted at industrial and power‑conversion markets, this capacitor delivers high ripple capability, stable performance to +105°C, and a 5,000‑hour endurance rating at 105°C, making it suitable for DC‑link smoothing, power supply filtering, and other high‑stress energy storage roles.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 450 V rated voltage and ±20% tolerance for high‑voltage energy storage and smoothing.
• High Ripple Current — 14.5 A low‑frequency ripple current (120 Hz) and 20.3 A high‑frequency ripple current (100 kHz) to support demanding AC ripple and switching environments.
• Endurance at Elevated Temperature — Rated for 5000 hours of life/ endurance at +105°C under rated ripple current, enabling extended service in high‑temperature installations.
• Leakage & Dissipation — Specified leakage current of 3300 µA and a tangent of loss angle (tan δ) of 0.2 (measured at 20°C, 120 Hz), providing predictable dissipation characteristics.
• Robust Packaging & Mounting — Radial can with screw terminals (M5 nominal bolt for φ76.2 mm diameter) for reliable electrical and mechanical connections in rugged assemblies.
• Operating Range & Compliance — Operates from −25°C to +105°C (for 160 to 500 V category) and is RoHS compliant.
• Form Factor — Physical size φ76.2 × 110 mm length, supplied in cardboard packing and currently in mass production for predictable sourcing.

Typical Applications

• Industrial Power Supplies — DC‑link smoothing and bulk energy storage in medium‑ and high‑voltage power supplies where 450 V rating and high ripple capability are required.
• Inverters & Motor Drives — Energy buffering and ripple attenuation on DC buses for frequency inverters and motor drive systems that operate at elevated temperatures.
• UPS and Energy Storage Systems — Bulk capacitance for ride‑through and conditioning of DC rails in uninterruptible power supplies and backup power modules.
• Power Conversion for Renewable Systems — DC smoothing and transient handling in solar or energy conversion equipment that benefit from high voltage and high ripple current capability.

Unique Advantages

• High‑Voltage, High‑Capacitance Combination: 450 V rating paired with 2700 µF provides substantial energy storage in a compact radial can for high‑voltage DC applications.
• Designed for High Ripple Environments: Specified LF and HF ripple currents (14.5 A @ 120 Hz, 20.3 A @ 100 kHz) reduce thermal stress and extend service life in switching applications.
• Long Endurance at 105°C: 5,000‑hour rated life at +105°C under rated ripple current supports reliability in continuous, high‑temperature operation.
• Secure Screw‑Terminal Mounting: Screw terminals enable robust electrical contact and mechanical retention, simplifying integration into industrial assemblies.
• Predictable Dissipation and Leakage: Specified tan δ (0.2 at 20°C/120 Hz) and defined leakage current support accurate thermal and system‑level planning.
• RoHS Compliant and Mass Production Ready: Environmentally compliant and available in mass production quantities for production scaling and supply continuity.
