LNY2W392MSEGBN

The LNY2W392MSEGBN is an aluminum electrolytic capacitor in a screw terminal radial can package designed for general-purpose power applications. It delivers 3.9 mF (3,900 μF) at a rated voltage of 450 V and is offered in a φ63.5 × 125 mm form factor.

Engineered for equipment downsizing and reliable high-voltage filtering, this part combines a 2000-hour endurance at 85°C with high ripple-current capability and RoHS compliance to support robust power designs.

Key Features

• Rated Capacitance & Voltage 3.9 mF (3,900 μF) nominal capacitance at a rated voltage of 450 V for high-voltage energy storage and filtering.
• Screw Terminal Mounting Radial can with screw terminals and M5 nominal bolt interface for secure, serviceable connections and easy installation.
• Endurance at Elevated Temperature Rated for 2,000 hours of ripple-current application at 85°C, meeting the specified endurance requirements after restoration to 20°C.
• High Ripple Current Handling Low-frequency ripple: 13.5 A at 120 Hz; high-frequency ripple: 18.9 A at 10 kHz—supporting demanding ripple conditions in power circuits.
• Leakage and Loss Specified leakage current of 3,970 μA and a tangent of loss angle (tan δ) of 0.25 (measurement conditions as specified).
• Operating Temperature Range Rated for −40°C to +85°C with low-temperature impedance characteristics noted in the datasheet.
• Physical Dimensions φ63.5 × 125 mm (L: 12.5 × D: 6.35 cm), suitable where a screw-terminal radial can is required.
• Regulatory RoHS compliant.

Typical Applications

• General-purpose power systems — Designed for use in general-purpose power assemblies that require high-voltage bulk capacitance.
• Equipment downsizing — Specified in the series documentation as suited for equipment downsizing where high capacitance is needed in a compact cylindrical package.
• Screw-terminal installations — Best for systems that require secure, serviceable connections via screw terminals and mounting brackets.

Unique Advantages

• High-voltage capacitance: 3.9 mF at 450 V provides substantial energy storage for high-voltage DC applications.
• Robust ripple capability: Separate specifications for 120 Hz (13.5 A) and 10 kHz (18.9 A) ripple currents allow designers to evaluate performance across frequency ranges.
• Long endurance at temperature: Rated 2,000 hours at 85°C under ripple conditions, supporting reliable operation in elevated-temperature environments.
• Serviceable screw-terminal format: Radial can with screw terminals and standard M5 nominal bolt interface enables straightforward mechanical mounting and field service.
• Clear electrical characteristics: Specified leakage current (3,970 μA) and tan δ (0.25) allow predictable integration into filter and energy-storage networks.
• RoHS compliant: Meets RoHS directive requirements for regulatory compliance in applicable regions.
