LNY2V392MSEFBB

The LNY2V392MSEFBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering a nominal capacitance of 3.9 mF (3900 µF) at a rated voltage of 350 V. It is a polar, radial can-style capacitor designed for general-purpose applications where high capacitance and secure screw-terminal connections are required.

With a rated operating temperature range of –40°C to 85°C and a load life specification of 2000 hours at 85°C, this part targets equipment that benefits from higher capacitance in a screw-terminal package and supports equipment downsizing with a compact φ51×130 mm form factor.

Key Features

• High nominal capacitance — 3.9 mF (3900 µF) at 350 V provides substantial charge storage in a single component.
• Screw-terminal mounting — Radial can with screw terminals and M5 bolt interface for robust, low-impedance electrical and mechanical connections.
• Operating temperature and endurance — Rated for –40°C to 85°C with a specified load life of 2000 hours at 85°C under rated ripple conditions.
• Ripple current performance — Capable of 14.8 A at 120 Hz and 20.72 A at 10 kHz, supporting designs with significant AC ripple stress.
• Electrical characteristics — Capacitance tolerance ±20%, tan δ of 0.25, and measured leakage current of 3.50 mA as provided in the product data.
• Packaging and status — Supplied in cardboard packing and currently in mass production.
• Regulatory — RoHS compliant per product data.

Typical Applications

• General-purpose equipment — Use where a 3.9 mF, 350 V polarized capacitor with screw terminals is needed for energy storage or filtering in general-purpose assemblies.
• Equipment downsizing — Higher capacitance in the LNY series supports designs that aim to reduce component count or enclosure size while maintaining capacitance requirements.
• High-ripple environments — Suitable for applications that require capacitors rated for substantial ripple current, leveraging the specified ripple current values at 120 Hz and 10 kHz.

Unique Advantages

• High-capacitance single component — 3900 µF at 350 V reduces the need for parallel components to achieve required capacitance.
• Secure screw-terminal interface — Screw terminals and M5-compatible bolt dimensioning provide reliable electrical and mechanical connections for demanding assemblies.
• Validated endurance — Load life specified as 2000 hours at 85°C under rated ripple conditions supports predictable long-term performance planning.
• Measured ripple capability — Published ripple current ratings (14.8 A at 120 Hz and 20.72 A at 10 kHz) give clear constraints for thermal and design calculations.
• Wide ambient range — Rated from –40°C to 85°C to accommodate a broad range of operating conditions specified in the product data.
• Regulatory compliance — RoHS compliance simplifies environmental-conformant sourcing.
