LNT2D103MSE

The LNT2D103MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, optimized for general-purpose power filtering and energy storage in systems requiring high capacitance at elevated voltages. It provides 10,000 µF of capacitance at a 200 V rating with a radial can package and screw terminals for secure, high-current connections.

Designed to operate over a wide temperature range and with specified ripple handling and endurance at 105°C, this part suits industrial and power-electronics applications that need dependable bulk capacitance and robust terminal connections.

Key Features

• High Capacitance: 10,000 µF (10 mF) nominal capacitance for bulk energy storage and low-frequency smoothing.
• 200 V Rated Voltage: Rated for 200 V operation, enabling use in higher-voltage power rails within its series range.
• Temperature Range & Endurance: Operating temperature −25°C to +105°C with a rated life of 2000 hours at 105°C under applied rated ripple current.
• Low-Frequency Ripple Current: 8.2 A at 120 Hz to handle substantial AC ripple on power supplies.
• High-Frequency Ripple Current: 9.84 A at 100 kHz for improved performance in switching and high-frequency applications.
• Leakage & Dissipation: Leakage current specified at 4240 µA and tan δ (DF) of 0.2 measured at 20°C, 120 Hz—data useful for thermal and loss budgeting.
• Screw-Terminal Package: Radial can with screw terminals for secure bolted connections; for φ76.2 body diameter, nominal bolt size is M5 (series dimension data).
• Mechanical Size: Body diameter φ76.2 mm × length 120 mm (L: 12.0 cm × D: 7.62 cm), supplied in cardboard packing and available in mass production.
• Capacitance Tolerance: ±20% at 120 Hz, 20°C (specified as −20% to +20%).
• RoHS Compliant: Meets RoHS requirements as noted for the LNT series.

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy buffering on higher-voltage DC rails where 200 V rating and high ripple current capability are required.
• Inverters and Motor Drives: DC-link smoothing where secure screw-terminal connections and robust high-capacitance storage improve system stability.
• Raw Power Filtering: Bulk decoupling for bridge rectifiers and intermediate DC circuits in commercial power conversion equipment.

Unique Advantages

• Substantial Bulk Storage: 10,000 µF at 200 V provides significant energy reserve for smoothing and transient support in power systems.
• High Ripple Handling: Specified ripple currents at both low and high frequency (8.2 A at 120 Hz, 9.84 A at 100 kHz) reduce the need for parallel components to share ripple stress.
• Robust Mechanical Termination: Screw-terminal construction with M5 nominal bolt (for φ76.2 size) enables reliable bolted connections for high-current paths and easier field installation.
• Elevated Operating Temperature & Rated Life: Rated for continuous operation up to 105°C with a defined 2000-hour life at that temperature under rated ripple current, aiding predictable long-term performance.
• Clear Specification Data: Measured tan δ, leakage current, tolerance, and dimensional data provided for accurate thermal, electrical, and mechanical integration.
• Regulatory Compliance: RoHS-compliant construction supports restrictive-substance requirements for modern electronics manufacturing.
