LNT1A474MSE

The LNT1A474MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series. It provides very high bulk capacitance (470000 µF) at a 10 V rating in a radial can with screw terminals for secure, high-current connections.

Designed for general-purpose power applications that require large energy storage and high ripple-current capability, this capacitor pairs a wide operating temperature range (−40 °C to +105 °C) with a specified endurance of 2000 hours at 105 °C.

Key Features

• High Capacitance — 470000 µF nominal capacitance (470 mF) with tolerance −20% to +20% for significant bulk energy storage.
• Rated Voltage — 10 V DC rated voltage suitable for low-voltage power rails and bulk storage applications.
• Ripple-Current Capability — Low-frequency ripple current 17 A at 120 Hz and high-frequency ripple current 19.55 A at 100 kHz for demanding ripple and filtering performance.
• Loss and Leakage — tanδ = 2.4 (measured at 20 °C, 120 Hz) and leakage current specified at 5000 µA to allow designers to budget dissipation and standby drain.
• Thermal and Lifecycle — Operating temperature range −40 °C to +105 °C with a rated endurance of 2000 hours at 105 °C under rated ripple conditions.
• Mechanical and Mounting — Screw terminal radial can package (φ90 × 140L, size L: 14 × D: 9 cm) for robust, field-friendly connections; packaged in cardboard for handling.
• Polarized Construction — Polarized electrolytic design; observe polarity during installation.
• RoHS Compliant — Conforms with RoHS requirements as stated in the product data.

Typical Applications

• General Purpose Power Systems — Large bulk capacitance and high ripple-current ratings make this capacitor suitable where significant energy storage and smoothing are required.
• Industrial Power Supplies — Screw-terminal mounting and high ripple capability support secure connections and robust performance in industrial power modules and DC distribution.
• Energy Storage and Smoothing — The 470000 µF capacitance and 10 V rating provide substantial local energy buffering for low-voltage rails and load transients.

Unique Advantages

• Very high bulk capacitance: 470000 µF delivers large energy storage in a single component, reducing the number of parts required for bulk filtering.
• Designed for high ripple: Rated ripple currents of 17 A (120 Hz) and 19.55 A (100 kHz) help manage AC stress and thermal loading in power circuits.
• Robust screw-terminal mounting: Provides secure, low-resistance connections suitable for high-current installations and easier field assembly.
• Wide operating range and proven endurance: −40 °C to +105 °C operation with 2000 hours life at 105 °C under rated ripple current supports reliable use in thermally demanding environments.
• Measurable electrical characteristics: Specified tanδ and leakage current values allow precise thermal and leakage budgeting in system design.
• Regulatory compliance: RoHS status is documented for use in compliant assemblies.
