LNY2W392MSEHBN

The LNY2W392MSEHBN is a Nichicon aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-ripple applications. It delivers 3.9 mF capacitance at a 450 V rating with a compact φ76.2 × 95 mm can size and is offered in mass production with cardboard packing.

Engineered for equipment downsizing and robust power systems, this capacitor combines high capacitance and high allowable ripple current with a 2000-hour load life at 85°C and an operating temperature range of −40°C to 85°C.

Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) rated at 450 V for high energy storage in a single component.
• Ripple Current Performance: 14.0 A low-frequency ripple current at 120 Hz and 19.6 A high-frequency ripple current at 10 kHz, enabling sustained AC stress handling.
• Loss & Leakage: Tan δ 0.25 (DF) at 20°C, 120 Hz and leakage current specified at 3970 µA (per product data), supporting predictable electrical behavior.
• Endurance & Temperature Range: Rated load life of 2000 hours at 85°C; operating temperature −40°C to +85°C for wide environmental tolerance.
• Mechanical & Mounting: Screw terminal radial can (φ76.2 × 95 mm / L: 9.5 × D: 7.62 cm) with robust screw terminals for secure mechanical and electrical connection.
• Tolerance & Polarization: ±20% capacitance tolerance (120 Hz, 20°C); polarized electrolytic design.
• Regulatory & Production: RoHS compliant and in mass production; packaged in cardboard for shipment.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing where 450 V rating and high ripple capability reduce stress on downstream circuitry.
• Power Conversion and Inverters: DC link and filtering duties in high-voltage converters benefiting from high capacitance and sustained ripple current ratings.
• Motor Drives and Drivesystems: Energy buffering and ripple absorption in medium- to high-voltage drive systems requiring reliable endurance at elevated temperature.

Unique Advantages

• High Voltage, High Capacitance Combination: 450 V rating combined with 3.9 mF capacitance reduces the need for multiple lower-voltage parts.
• High Ripple Endurance: Separate low- and high-frequency ripple ratings (14.0 A at 120 Hz, 19.6 A at 10 kHz) provide clear design margins for AC stress management.
• Designed for Equipment Downsizing: High capacitance in a compact φ76.2 × 95 mm can supports smaller power assemblies.
• Long-Life Rating: 2000-hour load life at 85°C offers predictable aging and service planning for deployed systems.
• Robust Mechanical Connection: Screw-terminal mounting simplifies installation and maintenance in heavy-current, serviceable applications.
• Regulatory Compliance & Supply: RoHS compliant and available in mass production to support volume procurement.
