LNT1E474MSEN

The LNT1E474MSEN is a screw-terminal aluminum electrolytic capacitor offering 470000 µF (470 mF) at 25 V in a robust radial can with screw terminals. It delivers very high bulk capacitance combined with elevated ripple-current capability for general-purpose power electronics applications.

Designed for operation from −40°C to +105°C with a rated endurance of 2000 hours at 105°C, this capacitor is targeted at systems that require large energy-storage capacity, high ripple-current handling, and secure screw-terminal connections.

Key Features

• High Capacitance: 470000 µF (470 mF) nominal capacitance for substantial bulk energy storage and smoothing of low-voltage DC rails.
• Rated Voltage: 25 V working voltage suitable for low-voltage power systems.
• Screw Terminal Package: Radial can with screw terminals (φ90 size) and M5 nominal bolt—provides secure, high-current connections for heavy-duty assemblies.
• High Ripple Current: Low-frequency ripple current 22.4 A (120 Hz) and high-frequency ripple current 25.76 A (100 kHz), enabling effective dissipation of AC currents superimposed on DC.
• Thermal and Endurance Performance: Operating range −40°C to +105°C with an endurance rating of 2000 hours at 105°C under rated ripple current.
• Electrical Characteristics: Capacitance tolerance ±20%; tangent of loss angle (tan δ) 1.5 measured at 20°C, 120 Hz; leakage current specified as 5000 µA.
• Packaging & Production: Cardboard packing, RoHS compliant and in mass production.

Typical Applications

• Power supply bulk smoothing: Large capacitance and high ripple-current ratings make it suitable for DC link and hold-up applications where minimizing voltage ripple is critical.
• Industrial power electronics: Robust screw-terminal connections and high ripple capability support use in motor drives, inverters, and industrial converters operating up to 25 V DC.
• UPS and energy-storage modules: High capacitance and endurance at 105°C provide bulk energy buffering for short-term hold-up and load transients.
• DC distribution and power racks: Designed for systems that require concentrated bulk capacitance with secure mechanical and electrical connections via screw terminals.

Unique Advantages

• Substantial bulk energy capacity: 470000 µF reduces ripple and extends hold-up time without parallel arrays of smaller capacitors.
• High ripple-current tolerance: 22.4 A (120 Hz) / 25.76 A (100 kHz) ratings lower internal heating under AC stress and support heavier current loads.
• Durable screw-terminal interface: M5 screw terminals on a φ90 can provide reliable, low-resistance connections for high-current wiring and secure mechanical mounting.
• Wide operating temperature and rated endurance: −40°C to +105°C operation with 2000 hours endurance at 105°C for reliable performance in elevated-temperature environments.
• Measured performance data: Specified tan δ (1.5 at 20°C, 120 Hz) and leakage current (5000 µA) allow straightforward thermal and loss budgeting in designs.
• Production-ready supply: RoHS compliant and listed as mass production with cardboard packing for standard handling and assembly processes.
