LNX2W332MSEH

The LNX2W332MSEH is a screw-terminal aluminum electrolytic capacitor manufactured by Nichicon. It delivers 3,300 µF capacitance at a 450 V rating in a radial can with robust screw terminals for secure, low-impedance connections.

Engineered for industrial power applications, this part is suited for inverter circuitry and other high-ripple, extra-high-voltage uses. Key value propositions include high ripple-current handling, extended operational life at elevated temperature, and RoHS compliance.

Key Features

• Capacitance & Voltage: 3,300 µF nominal capacitance with a 450 V rated voltage, suitable for high-voltage power circuits.
• High Ripple Current: Designed to handle significant ripple currents — 9.7 A at 120 Hz and 13.58 A at 100 kHz — supporting demanding power-conversion loads.
• Long Endurance at Elevated Temperature: Rated life of 20,000 hours at +85 °C when operated under the specified ripple current, delivering sustained performance in hot environments.
• Package & Termination: Radial can with screw terminals for secure mechanical and electrical connection, simplifying installation in power racks and assemblies.
• Operating Range & Stability: Specified operating temperature range of −25 °C to +85 °C with low-temperature impedance ratio (Z(−25 °C)/Z(+20 °C) = 8) and ±20% capacitance tolerance at 120 Hz, 20 °C.
• Leakage & Reliability: Leakage current specified as not more than 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at rated voltage, per datasheet endurance criteria.
• Compliance & Safety Options: RoHS compliant; flame-retardant electrolyte options are available for additional safety requirements.
• Physical Dimensions: Compact radial can size with body dimensions L: 11 cm × D: 7.62 cm and maximum seated height specified for mounting consideration.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing in industrial supplies where sustained high-voltage operation and ripple tolerance are required.
• Inverter Circuitry: DC link and filter applications in inverter systems that demand high ripple-current handling and long operational life at elevated temperatures.
• General Purpose Power Electronics: Use in high-voltage power-conversion circuits and other general-purpose designs requiring polar aluminum electrolytic capacitors with screw terminals.

Unique Advantages

• High Ripple Capability: Measured ripple ratings at both low and high frequency help ensure reliable performance in converter and inverter environments.
• Extended High‑Temperature Life: 20,000‑hour endurance at +85 °C under rated ripple current supports long maintenance intervals and predictable life-cycle planning.
• Robust Screw-Terminal Design: Screw terminals provide secure, low-resistance connections suitable for heavy-current bus work and field serviceability.
• Extra‑High Voltage Support: 450 V rating enables use in higher-voltage power systems without needing series strings of lower-voltage capacitors.
• Regulatory Compliance: RoHS compliance and optional flame-retardant electrolyte reduce environmental and flammability concerns in regulated assemblies.
• Clear Electrical Limits: Specified leakage current and tolerance figures provide verifiable parameters for design verification and reliability analysis.
