LNX2W472MSEH

The LNX2W472MSEH is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for high‑voltage, high‑reliability power applications. It combines a large 4700 µF capacitance with a 450 V rating and a rugged screw‑terminal package to support industrial power supplies and inverter circuitry.

Engineered for long operational life, the part is specified for 20,000 hours at +85 °C under rated ripple conditions and is RoHS compliant, making it suitable for demanding designs that require sustained high ripple performance and robust mounting.

Key Features

• High Capacitance & Voltage: 4700 µF capacitance at a 450 V rated voltage for bulk energy storage in high‑voltage circuits.
• Long Life Endurance: Rated for 20,000 hours at +85 °C under standard ripple current, supporting extended service intervals in continuous‑use systems.
• High Ripple Current Capability: Specified ripple current of 12.9 A at 120 Hz and 18.06 A at 100 kHz, enabling effective smoothing in high‑power, high‑frequency applications.
• Robust Mechanical Package: Radial can with screw terminals (φ76.2 × 150 mm) for secure electrical and mechanical connections in industrial assemblies.
• Operating Temperature Range: −25 °C to +85 °C to accommodate a wide range of environmental conditions.
• Capacitance Tolerance & Polarization: ±20% tolerance and polarized construction; suitable for DC link and bulk filtering use cases.
• Leakage Current Specification: Leakage current after 5 minutes is limited to 3√(C·V) µA or 5 mA, whichever is smaller, measured at 20 °C.
• Regulatory Compliance: RoHS compliant as specified for the LNX series.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing for high‑voltage industrial supplies, including inverter front‑ends.
• Inverter Circuitry: DC link and ripple attenuation in inverter stages where high capacitance and elevated voltage rating are required.
• High‑Voltage Power Systems: Energy buffering and filtering in high‑voltage assemblies that demand sustained ripple handling and long endurance.

Unique Advantages

• High Energy Density at Elevated Voltage: 4700 µF at 450 V provides substantial bulk capacitance for high‑voltage systems without multiple smaller capacitors.
• Designed for Long Service Life: 20,000‑hour endurance at +85 °C under rated ripple current reduces maintenance frequency and lifecycle costs.
• Strong Ripple Performance: Measured ripple current ratings at 120 Hz and 100 kHz support both low‑ and high‑frequency power conversion topologies.
• Secure, Serviceable Termination: Screw‑terminal can construction simplifies installation and replacement in industrial environments.
• Measured Leakage and Stability: Specified leakage current limits and tolerance control support predictable behavior after voltage application and aging.
• Regulatory Alignment: RoHS compliance supports deployment in regions and projects requiring restricted‑substance conformity.
