LNC2W472MSEH

The LNC2W472MSEH is a screw-terminal, polarized aluminum electrolytic capacitor designed for high-voltage power electronics. It delivers 4700 µF capacitance at a 450 V rating in a compact radial can with screw terminals, targeting industrial power supplies and inverter/regenerative circuits.

Key value propositions include high ripple-current capability, a 5000-hour load life at 85°C, and a wide operating temperature range from −40°C to 85°C, making it suitable for continuous-duty power applications where high voltage, long life and reliable mounting are required.

Key Features

• Capacitance & Tolerance — 4.7 mF (4700 µF) with ±20% tolerance, specified at 120 Hz, 20°C for predictable energy storage and decoupling performance.
• High Voltage Rating — Rated voltage of 450 V for use in high-voltage converter and inverter stages.
• High Ripple Current — Ripple capacity of 19.2 A at 120 Hz and 26.88 A at 100 kHz, supporting heavy AC ripple and high-frequency charge–discharge loads.
• Long Operational Life — Load life of 5000 hours at 85°C when subjected to rated ripple, enabling robust continuous operation.
• Thermal Range — Operating temperature from −40°C to 85°C to cover a broad range of industrial environments.
• Low Loss and Leakage — Specified tan δ of 0.2 and leakage current listed as 4.36 mA for controlled dielectric loss and minimal DC leakage.
• Mechanical & Mounting — Radial can with screw terminals for secure electrical and mechanical connection in power assemblies; size listed as φ76.2x115L (L: 11.5 × D: 7.62 cm).
• RoHS Compliant — Conforms to RoHS requirements as stated in the product data.

Typical Applications

• Industrial Inverters — Energy storage and smoothing in inverter DC-link circuits where 450 V rating and high ripple capability are required.
• Regenerative Drives — High-frequency regenerative voltage handling for AC servomotors and servo drive power stages.
• Power Supplies — Bulk energy storage and ripple management in industrial power supplies subject to sustained ripple currents and elevated ambient temperatures.

Unique Advantages

• High-voltage capacity: 450 V rating enables use in DC-link and high-voltage power systems without series stacks.
• Engineered for ripple: Specified ripple currents at both low and high frequency (19.2 A at 120 Hz, 26.88 A at 100 kHz) support demanding AC and high-frequency loads.
• Long endurance under load: 5000-hour rated life at 85°C under ripple stress provides predictable service life for continuous-duty applications.
• Secure screw-terminal mounting: Screw terminals simplify installation and provide reliable electrical/mechanical connection in power assemblies.
• Compact radial can: Smaller-sized design within the LNC series footprint while maintaining higher ripple capability compared with earlier series variants.
• Regulatory compliance: RoHS conformity supports integration into systems targeting restricted-substance compliance.
