LNT2V392MSEG

The LNT2V392MSEG is a screw-terminal aluminum electrolytic capacitor offering 3.9 mF (3900 µF) rated at 350 V. It is a polarized, radial can design built for general-purpose high-voltage power applications that require bulk capacitance and secure, high-current connections.

Engineered for sustained operation up to 105°C with a rated lifetime of 5,000 hours at that temperature, this part targets power conversion and filtering designs where high-voltage bulk capacitance, ripple handling, and robust mechanical termination are required.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 350 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Screw-terminal Power Package — Radial can with screw terminals (φ63.5 housing) and M5 nominal bolt terminals for secure, high-current connections.
• High ripple-current capability — Rated ripple current of 16.8 A at 120 Hz and 23.52 A at 100 kHz to support heavy AC ripple conditions in power systems.
• Long life at elevated temperature — Endurance specified as 5,000 hours at +105°C under DC bias plus rated ripple current.
• Wide operating temperature — Specified operating range from −25°C to +105°C for applications at this voltage class.
• Low leakage — Specified leakage current of 3500 µA after initial application of rated voltage.
• RoHS compliant & production ready — RoHS status compliant; supplied in cardboard packing and in mass production status.

Typical Applications

• High-voltage power supplies — Bulk capacitance and smoothing at 350 V DC for power-supply front ends and high-voltage rails.
• Power conversion systems — Energy buffering and ripple smoothing in industrial converters and inverters that require secure screw-terminal connections.
• UPS and energy storage modules — Bulk storage and discharge support where high-voltage capacitance and reliable ripple handling are needed.

Unique Advantages

• High-voltage bulk capacitance: 3.9 mF at 350 V provides substantial stored energy for smoothing and buffering high-voltage rails.
• Robust screw-terminal mounting: M5 screw terminals on a φ63.5 can deliver secure mechanical and electrical connections for high-current service.
• Designed for sustained high-temperature operation: Rated 5,000 hours at 105°C for applications that operate at elevated ambient or internal temperatures.
• High ripple capability: Specified ripple currents of 16.8 A (120 Hz) and 23.52 A (100 kHz) support demanding AC ripple conditions in power electronics.
• Clear mechanical footprint: Housing size φ63.5 × 130 mm (D × L) simplifies mechanical planning for chassis-mounted power modules.
• Regulatory readiness: RoHS compliance and mass-production availability facilitate integration into commercial and industrial product lines.
