LNX2W222MSEH

The LNX2W222MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series, rated at 450 V with 2200 µF nominal capacitance. It is a polarized, radial can package with screw terminals designed for secure electrical and mechanical connections in power assemblies.

Engineered for industrial power supplies and inverter circuitry, this capacitor delivers high ripple-current capability and extended operational life—providing reliable DC-link and filtering performance in extra-high-voltage applications up to +85°C.

Key Features

• High voltage, high capacitance: 2.2 mF (2200 µF) capacitance with a 450 V rated voltage for extra-high-voltage power stages.
• Screw-terminal mounting: Radial can with screw terminals provides robust, serviceable connections suitable for industrial assemblies.
• Long ripple life: Specified endurance of 20,000 hours at +85°C when the standard ripple current is applied, supporting long-term operation under load.
• High ripple-current capability: 7.1 A at 120 Hz and 9.94 A at 100 kHz, enabling use in high-stress power-conversion environments.
• Temperature and stability: Operating range −25 °C to +85 °C with an impedance ratio Z(−25 °C)/Z(+20 °C) of 8 for predictable low-temperature behavior.
• Leakage current specification: After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA (whichever is smaller), aiding power-loss budgeting.
• Mechanical and dimensional data: Package dimensions L: 9.0 cm × D: 7.62 cm, with a maximum seated height of 3.543 inch; capacitance tolerance ±20%.
• Environmental compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Series options: The LNX series offers extended sizes (up to φ100 = 250L) and flame-retardant electrolyte types within the series where specified.

Typical Applications

• Industrial power supplies: DC smoothing and bulk energy storage in high-voltage industrial PSU designs.
• Inverter circuitry and motor drives: DC-link and filtering for inverter stages that require high ripple current handling and long life.
• High-ripple, extra-high-voltage power electronics: Filtering and energy buffering in power conversion systems operating at elevated voltages and ripple levels.
• Power modules and assemblies: Secure screw-terminal connections simplify installation and maintenance in bench and rack-mounted power systems.

Unique Advantages

• Extended operational lifetime: 20,000-hour endurance at +85 °C under rated ripple current reduces maintenance and replacement cycles.
• High ripple tolerance: Measured ripple-current ratings at both 120 Hz and 100 kHz support a wide range of switching and line-frequency applications.
• Extra-high-voltage capability: 450 V rating enables use in designs that require higher DC voltages without parallel stacking.
• Robust electrical connections: Screw-terminal package simplifies secure mounting and reliable power interconnects in industrial environments.
• Predictable leakage behavior: Clear leakage-current limits allow accurate power-loss and thermal planning in system design.
• Regulatory alignment: RoHS compliance supports environmental and regulatory objectives for commercial and industrial products.
