LNT1H474MSEB

The LNT1H474MSEB from Nichicon is a screw-terminal aluminum electrolytic capacitor offering very high bulk capacitance in a radial can package. It combines a 470,000 µF (470 mF) capacitance with a 50 V rated voltage, designed for general-purpose power applications that require substantial energy storage and high ripple-current capability.

Built for demanding thermal environments, this capacitor supports operation from −40°C to +105°C and is specified with an endurance of 2,000 hours at 105°C. It is supplied in cardboard packing and is in mass production.

Key Features

• High Capacitance: 470,000 µF (470 mF) bulk capacitance provides large energy storage for smoothing and decoupling in power systems.
• Rated Voltage and Tolerance: 50 V rated voltage with capacitance tolerance of ±20% (−20% to +20%) measured at 120 Hz, 20°C.
• High Ripple Current Handling: Low-frequency ripple current of 26.1 A at 120 Hz and high-frequency ripple current of 30.02 A at 100 kHz enable robust AC load handling.
• Thermal and Endurance Rating: Operating temperature range −40°C to +105°C with rated life/endurance of 2,000 hours at 105°C under specified ripple and bias conditions.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low-resistance connections for high-current applications.
• Electrical Loss and Leakage: Specified tangent of loss angle (tan δ) of 0.75 (measured at 20°C, 120 Hz) and leakage current specified at 5,000 µA.
• Large Can Dimensions: Size φ100 × 250L (L: 25 cm × D: 10 cm), enabling the high capacitance and ripple capabilities in a robust package.
• Compliance and Availability: RoHS compliant and listed as mass production by the manufacturer Nichicon.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing where large capacitance and high ripple current are required.
• Power supplies and converters: Filtering and hold-up in designs that operate up to 50 V and demand sustained ripple performance at elevated temperatures.
• Industrial equipment: Applications that require a polarized screw-terminal capacitor with long endurance at +105°C for reliable operation under continuous load.

Unique Advantages

• Substantial energy density: 470,000 µF provides significant bulk capacitance to reduce voltage sag and support transient loads.
• Designed for high ripple loads: Specified ripple currents (26.1 A @120 Hz, 30.02 A @100 kHz) allow direct use on high-current rails with reduced thermal stress.
• Robust high-temperature endurance: Rated for 2,000 hours at 105°C, enabling longer service life under elevated operating temperatures.
• Secure high-current connections: Screw-terminal, radial can package simplifies mechanical mounting and delivers low-impedance power connections.
• Clear electrical characterization: Provided tan δ and leakage current specifications support predictable design integration and margining.
• RoHS compliant and production-ready: Manufacturer production status and RoHS compliance simplify procurement and regulatory tracking.
