LNY2W272MSEF

The LNY2W272MSEF is a screw‑terminal aluminum electrolytic capacitor providing 2700 μF at a rated voltage of 450 V in a radial can with screw terminals. It is designed for general‑purpose power applications that require high capacitance, high voltage handling and robust terminal connections.

With a wide operating temperature range of −40°C to 85°C, a 2000‑hour endurance at 85°C under rated ripple conditions, and RoHS compliance, this part targets industrial and power electronics designs that need reliable bulk energy storage and high‑voltage filtering.

Key Features

• High Capacitance and Voltage: 2700 μF rated capacitance at 450 V for substantial energy storage and DC link smoothing in high‑voltage circuits.
• Screw Terminal Mounting: Radial can with screw terminals (M5 nominal bolt diameter for φ51) for secure, low‑impedance connections and easy installation.
• Ripple Current Capability: Low‑frequency ripple current 10.3 A (120 Hz) and high‑frequency ripple current 14.42 A (10 kHz) to support designs with significant AC ripple stress.
• Leakage and Loss Characteristics: Specified leakage current of 3300 μA and tangent of loss angle (tan δ) of 0.25 (measurement conditions per series datasheet).
• Thermal and Endurance Rating: Operating range −40°C to 85°C with an endurance (load life) of 2000 hours at 85°C when subjected to rated ripple current.
• Form Factor and Packaging: Compact φ51×145L can (L: 14.5 cm × D: 5.1 cm), radial package with screw terminals, supplied in cardboard packing and available in mass production quantities.
• Regulatory Compliance: RoHS compliant per the product specification.

Typical Applications

• High‑voltage power supplies: Bulk filtering and energy storage where a 450 V rating and 2700 μF capacitance are required to smooth DC rails.
• DC link and inverter circuits: DC link smoothing in power conversion stages that demand high ripple current capability and robust terminal connections.
• Industrial equipment: General‑purpose power reservoirs in industrial electronics operating across −40°C to 85°C with proven endurance under ripple stress.

Unique Advantages

• High energy density for high‑voltage designs: 2700 μF at 450 V provides substantial capacitance in a compact φ51 can for downsized power modules.
• Robust screw‑terminal interface: M5‑compatible screw terminals enable secure mechanical fastening and low contact resistance for heavy current paths.
• Designed for ripple stress: Specified ripple current ratings at 120 Hz and 10 kHz support both low‑frequency and higher‑frequency switching environments.
• Proven thermal endurance: 2000 hours at 85°C under rated ripple ensures predictable ageing behavior in elevated temperature conditions.
• Series‑level quality controls: Meets series specifications such as insulation resistance and voltage proof checks per the datasheet, supporting reliable deployment.
