LNT1K103MSEB

The LNT1K103MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, rated at 10,000 µF and 80 V. It is a polarized, radial can design intended for general-purpose power-electronic applications where high bulk capacitance and rugged screw-terminal connections are required.

Designed for sustained operation up to +105°C with a rated life of 2000 hours at 105°C, this capacitor provides high ripple-current capability and robust leakage characteristics in a φ51 × 80 mm package, shipped in cardboard packing and compliant with RoHS.

Key Features

• High Capacitance & Voltage: 10,000 µF nominal capacitance with an 80 V rated voltage, suitable for bulk energy storage and filtering in power systems.
• Temperature and Endurance: Operating range −40°C to +105°C with a life/endurance rating of 2000 hours at 105°C (when subjected to rated ripple and DC bias).
• Robust Ripple Performance: Low-frequency ripple current 5.4 A (120 Hz) and high-frequency ripple current 6.21 A (100 kHz), enabling effective smoothing under varying drive conditions.
• Leakage & Tolerance: Specified leakage current of 2680 µA and capacitance tolerance of −20% to +20%, allowing predictable behavior for margin-critical designs.
• Screw-Terminal, Radial Can Package: φ51 × 80 mm radial can with screw terminals (M5 nominal bolt for φ51), providing secure electrical and mechanical connections for larger current paths.
• Regulatory Compliance: RoHS-compliant construction to meet environmental directive requirements.

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy storage for general-purpose industrial power systems requiring high capacitance at elevated temperatures.
• Power Conversion and Conditioning: DC-link smoothing and ripple suppression in general-purpose converters and inverters.
• Motor Drives and Power Electronics: Energy buffering and transient suppression where a secure screw-terminal connection and high ripple handling are needed.

Unique Advantages

• Large Bulk Storage: 10,000 µF capacitance provides significant energy reservoir for smoothing and hold-up without parallel component complexity.
• High Voltage Margin: 80 V rating supports higher-voltage rails and provides headroom for demanding power designs.
• Designed for High Ripple Loads: Specified ripple currents at both low and high frequencies reduce the need for additional parallel components to handle AC stress.
• Temperature-Rated Reliability: Rated for −40°C to +105°C operation and specified endurance at 105°C, enabling deployment in warm environments with defined lifetime expectations.
• Solid Mechanical Termination: Screw-terminal radial can simplifies secure mounting and high-current connections, minimizing contact resistance in assemblies.
• Regulatory Alignment: RoHS compliance supports environmental requirements in modern product designs.
