LNX2J222MSEJBN

The LNX2J222MSEJBN is a screw-terminal aluminum electrolytic capacitor designed for extra-high voltage, high-ripple applications. As part of the LNX series, it offers 2.2 mF (2200 µF) capacitance at a 630 V rating, optimized for use in industrial power supplies and inverter circuitry.

Engineered for long service life and high ripple handling, this polarized radial can with screw terminals is intended for designs that require robust DC-link filtering and reliable high-voltage smoothing up to +85°C operating temperature.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) nominal capacitance rated at 630 V for extra-high voltage DC applications.
• Screw Terminal Mounting: Radial can with screw terminals provides a secure electrical and mechanical connection for high-current power assemblies.
• High Ripple Current: Rated ripple current of 10.7 A at 120 Hz and 14.98 A at 100 kHz to support heavy filtering and inverter duty cycles.
• Long-Life Endurance: Specified for long-life operation under rated ripple at +85°C (series specification for extended lifetime under rated ripple conditions).
• Temperature Range: Operates from −25°C to +85°C, with defined low-temperature impedance performance (Z(−25°C)/Z(+20°C) ≤ 8).
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current ≤ 3√(C·V) µA or 5 mA, whichever is smaller (measured at 20°C).
• Endurance Characteristics: After endurance testing under rated ripple, capacitance change is within ±20%, tan δ remains within specified limits, and leakage current stays within specified values.
• Environmental Compliance: RoHS compliant; flame-retardant electrolyte type available for series variants.

Typical Applications

• Industrial Power Supplies: DC-link smoothing and bulk energy storage in industrial power supply modules where high voltage and high ripple are present.
• Inverter Circuitry: Energy buffering and ripple suppression for inverter input/output stages in motor drives and power conversion systems.
• Extra-High Voltage Power Systems: Filtering and stabilization in applications that require capacitors rated for 630 V and above.

Unique Advantages

• High Ripple Handling: Designed ripple current ratings at both low and high frequencies reduce heating and extend service life in demanding power circuits.
• Robust Mechanical Termination: Screw terminals enable secure, low-resistance connections suitable for high-current assemblies and field serviceability.
• Proven Endurance: Series-level endurance specifications for extended operation at +85°C under rated ripple support longer maintenance intervals and predictable performance.
• Clear Electrical Limits: Explicit leakage current and impedance limits simplify thermal and reliability calculations for system designers.
• Compliance and Safety Options: RoHS compliance and availability of flame-retardant electrolyte types help meet regulatory and safety considerations.
