LNT1E474MSE

The LNT1E474MSE is a screw‑terminal aluminum electrolytic capacitor in Nichicon's LNT series, offering very high capacitance (470,000 µF) at a 25 V rating in a φ90 × 170L radial can with screw terminals. It is designed for general‑purpose power applications that require large bulk energy storage and high ripple handling in environments from −40°C to +105°C.

Key value comes from its combination of massive capacitance, high low‑ and high‑frequency ripple current capability, and rugged screw‑terminal packaging for secure power connections in high‑current systems.

Key Features

• High Capacitance — 470,000 µF (470 mF) provides substantial bulk energy storage for smoothing and DC‑link applications.
• Rated Voltage — 25 V nominal working voltage suitable for low‑voltage power rails.
• High Ripple Current — 22.4 A at 120 Hz and 25.76 A at 100 kHz, enabling effective handling of both low‑ and high‑frequency ripple currents.
• Thermal and Lifecycle Performance — Rated for operation from −40°C to +105°C with a specified life of 2,000 hours at 105°C under rated ripple conditions.
• Electrical Characteristics — Capacitance tolerance −20% to +20% and specified tan δ (loss tangent) of 1.5 measured at 20°C, 120 Hz; leakage current specified at 5,000 µA.
• Robust Mechanical Package — Radial can with screw terminals (φ90 × 170L, L:17 × D:9 cm) for secure bolted connections and straightforward mounting using brackets.
• RoHS Compliant & Mass Production — RoHS status compliant; product status: mass production with cardboard packing.

Typical Applications

• Bulk Energy Storage / Power Supply Filtering — Large capacitance and high ripple current capability support smoothing and bulk storage on DC rails.
• High‑Current Power Electronics — Screw‑terminal mounting and high ripple ratings suit high‑current power conversion equipment and power conditioners.
• Industrial Power Systems — Wide operating temperature range (−40°C to +105°C) and 2,000‑hour endurance at 105°C make it suitable for demanding industrial environments.

Unique Advantages

• Massive Energy Density: 470,000 µF provides substantial capacitance in a single radial can, reducing the need for parallel components.
• Dual‑Frequency Ripple Handling: Separate ripple specifications at 120 Hz and 100 kHz (22.4 A / 25.76 A) give predictable performance across real‑world ripple spectra.
• Screw‑Terminal Reliability: Bolted screw terminals provide secure, low‑impedance connections for heavy current paths and simplified field replacement.
• Engineered for Elevated Temperatures: Rated to +105°C with defined endurance (2,000 h at 105°C under rated ripple), supporting sustained operation in hot enclosures.
• Defined Electrical Limits: Clear limits for leakage current (5,000 µA), tan δ, and capacitance tolerance allow straightforward derating and system design.
• Production‑Ready Supply: RoHS compliant and in mass production with cardboard packing for standard handling and logistics.
