LNT1A474MSEN

The LNT1A474MSEN from Nichicon is a large-can aluminum electrolytic capacitor in the LNT series, featuring a screw-terminal radial can package and a nominal capacitance of 470,000 µF at 10 V. Engineered for general-purpose power applications, it delivers substantial bulk capacitance and high ripple-current capability in a robust screw-terminal form factor.

This capacitor is specified for operation from –40°C to +105°C, with an endurance rating of 2000 hours at 105°C when subjected to rated ripple current, and is RoHS compliant. Its combination of high capacitance, defined lifecycle, and high allowable ripple currents addresses demanding power smoothing and bulk-energy requirements in industrial and power-system designs.

Key Features

• High Bulk Capacitance — 470,000 µF (470 mF) nominal capacitance provides significant energy storage for DC bus smoothing and hold-up applications.
• Rated Voltage — 10 V rated voltage for low-voltage power systems and DC-link applications.
• High Ripple Current Handling — Low-frequency ripple current of 17 A (at 120 Hz) and high-frequency ripple current of 19.55 A (at 100 kHz) to support heavy AC ripple and switching converter environments.
• Electrical Losses — tan δ (dissipation factor) specified as 2.4, measured at 20°C and 120 Hz, for predictable loss characteristics in design calculations.
• Leakage Current — Specified leakage current of 5000 µA after voltage application, useful for end‑system power budgeting.
• Thermal and Endurance Rating — Operating temperature range from –40°C to +105°C with a rated life of 2000 hours at 105°C under rated ripple conditions.
• Rugged Screw-Terminal Can — Radial, screw-terminal package (φ90 × 140 mm) provides secure mechanical and electrical connections for high-current assemblies.
• Regulatory — RoHS compliant and in mass production for reliable sourcing.

Typical Applications

• General-purpose power systems — Bulk smoothing and energy storage in systems that require very large capacitance and high ripple-current capability.
• Industrial power supplies — DC-link and reservoir capacitors in industrial converters and rectifier stages where sustained ripple currents and elevated operating temperatures are expected.
• Power conditioning and hold-up — Energy buffering for short hold-up requirements and for stabilizing DC rails under transient load conditions.

Unique Advantages

• Massive capacitance in a single component: 470,000 µF reduces component count compared to smaller capacitors in parallel, simplifying BOM and layout.
• Designed for high ripple environments: 17 A (120 Hz) and 19.55 A (100 kHz) ripple-current ratings support both low- and high-frequency power converter stress.
• High-temperature endurance: Rated life of 2000 hours at 105°C under rated ripple current provides predictable lifetime behavior in hot operating environments.
• Secure mechanical and electrical connection: Screw-terminal radial can package (φ90 × 140 mm) enables robust mounting and reliable high-current terminations.
• Measured loss specification: tan δ = 2.4 (20°C, 120 Hz) gives designers a defined dissipation parameter for thermal and efficiency calculations.
• Regulatory compliance: RoHS compliance supports environmentally regulated product designs.
