LNX2W472MSEG

The LNX2W472MSEG is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for high-voltage, high-ripple applications. With 4.7 mF (4700 µF) capacitance at a 450 V rating and a proven 20,000-hour lifetime at 85°C, it targets industrial power electronics where bulk energy storage and ripple handling are critical.

Its combination of high voltage, high ripple-current capability and screw-terminal mounting makes it suitable for industrial power supplies, inverter circuitry and other general-purpose power systems requiring durable, long-life capacitors.

Key Features

• Capacitance & Voltage: 4.7 mF (4700 µF) nominal capacitance at a 450 V rated voltage for bulk energy storage in high-voltage rails.
• Long Life: Endurance rated 20,000 hours at +85°C when subjected to rated ripple current, supporting extended service intervals in continuous-duty systems.
• High Ripple Current: Rated ripple current of 13 A at 120 Hz and 18.2 A at 100 kHz, enabling effective smoothing in high-ripple power converters.
• Screw Terminal Mounting: Radial can with screw terminals for secure, low-resistance connections and robust mechanical mounting in industrial assemblies.
• Operating Temperature: Specified -25°C to +85°C to match typical industrial ambient ranges for power electronics.
• Tolerance & Polarization: ±20% capacitance tolerance (–20% to +20%) and polarized construction—appropriate for DC filtering and bulk applications.
• Form Factor & Packing: Physical size φ63.5 × 190L (L: 19 cm × D: 6.35 cm) in a radial can; supplied in cardboard packing for handling and storage.
• RoHS Compliant: Meets RoHS requirements for reduced hazardous substances.
• Series Attributes: Part of the LNX series noted for high ripple capability and suitability for extra-high-voltage applications; flame-retardant electrolyte types are available in the series.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and output filtering in industrial PSUs and converter stages where 450 V ratings and high ripple handling are needed.
• Inverter Circuits: DC link and smoothing applications in inverter and motor-drive systems that require sustained ripple performance and long life at elevated temperature.
• Power Conversion Modules: Filtering and energy buffering in high-voltage converters and chopper circuits to stabilize DC rails under heavy ripple loads.

Unique Advantages

• Extended operational life: 20,000-hour endurance at 85°C reduces replacement frequency and supports sustained operation in continuous-duty equipment.
• High ripple capacity: Elevated ripple-current ratings at both 120 Hz and 100 kHz help manage heating and maintain capacitance under demanding converter conditions.
• Robust electrical rating: 450 V rating and large capacitance combine to provide substantial energy storage in a single component, simplifying designs that need high-voltage bulk capacitance.
• Secure, serviceable mounting: Screw-terminal radial can construction allows reliable electrical and mechanical connections suitable for industrial assembly and maintenance.
• Regulatory compliance: RoHS compliance supports deployment in regions and products requiring restricted-substance adherence.
