LNT2H102MSEF

The LNT2H102MSEF is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, specified for 500 V operation with 1,000 µF capacitance. It is a polarized, radial can device designed for general-purpose high-voltage applications where robust capacitance, elevated temperature rating and secure screw-terminal mounting are required.

Key electrical and mechanical attributes include a 105°C operating rating, 2000-hour life at 105°C under rated ripple current, a tanδ of 0.20, and low-frequency and high-frequency ripple current ratings—making it suitable for demanding power environments that require stable capacitance and reliable terminal connections.

Key Features

• Capacitance & Voltage: 1,000 µF nominal capacitance with a 500 V rated voltage for high-voltage energy storage and filtering requirements.
• Temperature and Endurance: Rated for operation from –25°C to +105°C with a specified lifetime of 2000 hours at +105°C when subjected to DC bias plus rated ripple current.
• Mounting and Package: Screw terminal, radial can package (φ51 × 120 mm) for secure electrical connection and mechanical retention in rack or chassis installations.
• Tolerance and Polarization: ±20% capacitance tolerance at 120 Hz, 20°C; polarized construction for correct DC orientation.
• Loss and Leakage: Tangent of loss angle (tanδ) specified at 0.20 and measured leakage current of 2.12 mA after 5 minutes at rated voltage (typical test condition shown in datasheet).
• Ripple Current Capability: Rated ripple current of 5.5 A at 120 Hz and 7.7 A at 100 kHz to support both low-frequency and higher-frequency ripple environments.
• RoHS Compliance & Packaging: RoHS compliant and supplied in cardboard packing for mass-production handling.

Typical Applications

• High-voltage power electronics: Bulk energy storage and smoothing where a 500 V rated electrolytic is required and secure screw-terminal connections are preferred.
• Industrial power supplies: DC-link or filter capacitor in industrial converters and power modules operating up to +105°C.
• Chassis-mounted systems: Applications that benefit from a radial can with screw terminals for robust mechanical mounting and serviceable connections.

Unique Advantages

• High working voltage (500 V): Enables use in higher-voltage DC systems without stacking multiple lower-voltage capacitors.
• Elevated temperature rating: 105°C rating and a defined 2000-hour endurance at that temperature provide predictable lifetime performance under elevated operating conditions.
• Robust screw-terminal mounting: Screw terminals simplify installation and ensure reliable mechanical and electrical connections in heavy-duty assemblies.
• Dual-frequency ripple specification: Published ripple current at both 120 Hz and 100 kHz supports designs facing a range of ripple frequencies.
• Measured leakage and loss parameters: Specified leakage current (2.12 mA) and tanδ (0.20) help engineers size bleeder circuits and estimate dissipation.
• Production-ready packaging: Cardboard packing and mass-production availability streamline procurement and assembly planning.
