• Rated Voltage — 50 V DC rating for mid-voltage power systems.
• High Ripple Current — Supports 9.9 A at 120 Hz (low frequency) and 11.38 A at 100 kHz (high frequency), enabling effective smoothing and pulse filtering under heavy ripple conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.35 measured at 20°C, 120 Hz.
• Leakage Current — Specified leakage current of 4,590 µA.
• Temperature & Endurance — Operating range −40°C to +105°C with rated endurance of 2,000 hours at 105°C under rated ripple conditions.
• Robust Mechanical Package — Radial can with screw terminals (φ63.5 × 100L mm). Terminal hardware designed for M5 bolts on the φ63.5 size for reliable connection.
• Packaging & Compliance — Supplied in cardboard packing and produced for mass production; RoHS compliant.

Typical Applications

• Power-supply bulk filtering — High capacitance and rated ripple current make the LNT1H473MSEB suitable for bulk energy storage and smoothing in power supplies.
• DC link and power-electronics — Screw-terminal construction and substantial ripple capability support use as DC-link or intermediate storage in industrial converters and inverters.
• Industrial and general-purpose systems — Wide temperature range (−40°C to +105°C) and 2,000-hour endurance at 105°C suit extended operation in industrial environments.

Unique Advantages

• Large bulk capacitance: 47,000 µF provides significant charge storage for smoothing and transient energy demands.
• High ripple handling: 9.9 A (120 Hz) and 11.38 A (100 kHz) ratings allow the capacitor to handle heavy AC ripple across a range of frequencies.
• Secure screw-terminal interface: Screw terminals with M5 bolt nominal on the φ63.5 size deliver durable electrical and mechanical connections for high-current bus applications.
• Designed for elevated temperature operation: Rated to +105°C with a specified 2,000-hour life at that temperature under rated ripple, supporting long-term reliability in hot operating conditions.
• Clear mechanical footprint: φ63.5 × 100 mm can dimensions simplify layout planning for designers needing known radial can form factors.
• RoHS compliant and production-ready: Cardboard packing and mass-production status support procurement and volume deployment.
