The LNX2J392MSEJBN is an aluminum electrolytic capacitor in a screw-terminal, radial can package engineered for extra-high-voltage, high-ripple applications. It delivers 3.9 mF capacitance at a 630 V rating and is sized φ90 × 190L (L: 19 × D: 9 cm), making it suitable for demanding industrial power circuits.

Designed for inverter circuitry and industrial power supplies, this part emphasizes high ripple-current capability, long operational life under rated ripple, and options for flame-retardant electrolyte. It is RoHS compliant.

Key Features

• Capacitance & Voltage: 3.9 mF nominal capacitance with a 630 V rated voltage for extra-high-voltage applications.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low-impedance connections for high-current installations.
• High Ripple Current Handling: Rated ripple current up to 17.3 A at 120 Hz and 24.22 A at 100 kHz, suitable for high-ripple environments.
• Long Life Under Ripple: Specified long-life performance with 20,000 hours application of rated ripple current at +85°C.
• Operating Temperature Range: Specified for operation from −25°C to +85°C.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C).
• Physical Size: φ90 × 190L (L: 19 × D: 9 cm) providing a robust footprint for high-energy applications; extended family sizes are available up to φ100 = 250L.
• Compliance and Safety Options: RoHS compliant and available with a flame-retardant electrolyte option.
• Polarized Electrolytic Design: Polarized device intended for DC power applications.

Typical Applications

• Industrial Power Supplies: Energy smoothing and decoupling in industrial supplies where extra-high voltage and sustained ripple capability are required.
• Inverter Circuitry: DC link and filtering applications within inverter systems that demand high ripple-current endurance and reliable long-term operation.
• High-Ripple Power Systems: Applications that undergo frequent or sustained ripple stress benefit from the part's rated ripple current and long-life characteristics.

Unique Advantages

• Extra-High Voltage Rating: 630 V rating enables use in higher-voltage power conversion and energy storage scenarios where lower-voltage capacitors are unsuitable.
• High Ripple Capability: Measured ripple current specifications at both low and high frequencies (17.3 A @120 Hz, 24.22 A @100 kHz) allow reliable operation under heavy AC stress.
• Long Operational Life Under Load: Qualified for extended life under rated ripple at +85°C (20,000 hours), reducing replacement frequency in critical systems.
• Robust Mechanical Connection: Screw-terminal radial can construction delivers secure, low-resistance connections for high-current wiring and easy installation.
• Safety and Compliance Options: RoHS compliance and availability of flame-retardant electrolyte provide options for regulated or safety-conscious designs.
• Clear Leakage Limits: Defined leakage-current limit after voltage application supports predictable end-of-line testing and system-level reliability planning.
