LNT2G471MSEC

The LNT2G471MSEC is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, rated at 470 µF and 400 V with polarized construction. It is designed for general-purpose use where high-voltage energy storage and robust ripple handling are required.

Key value comes from its 105°C temperature rating, specified load life, and measured ripple-current capability, making it suitable for demanding high-voltage applications that require durable long-term performance and RoHS compliance.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing high-voltage energy storage in a single component.
• Screw Terminal Package: Radial can with screw terminals simplifies secure electrical and mechanical connections for power assemblies and serviceable installations.
• High Temperature Endurance: Rated for operation from –25°C to +105°C with a load life of 5,000 hours at 105°C when subjected to rated ripple current and DC bias.
• High Ripple Current Capability: Specified ripple current of 3.1 A at 120 Hz and 4.34 A at 100 kHz, supporting applications with significant AC components on the DC bus.
• Polarized Construction: Polarized electrolytic design for DC smoothing and bulk energy storage roles where polarity is controlled.
• RoHS Compliant: Manufactured to meet RoHS environmental requirements for lead-free assembly.
• Physical Dimensions: Size L: 10 × D: 3.5 cm with a maximum seated height of 3.937 inch, suitable for chassis- or bracket-mounted power modules.

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling in high-voltage DC power supplies where 470 µF at 400 V and high ripple capability are required.
• Power conversion and energy storage: Energy reservoir in medium- and high-voltage converter stages that operate up to 105°C and demand long endurance.
• Serviceable industrial assemblies: Screw-terminal mounting enables robust, serviceable connections for field-replaceable power modules and rack-mounted systems.

Unique Advantages

• High-voltage single-component solution: 400 V rating with 470 µF capacitance reduces the need for parallel components when high-voltage bulk capacitance is required.
• Designed for elevated temperatures: 105°C rating and a 5,000-hour load life at that temperature provide predictable lifetime behavior in hot operating environments.
• Measurable ripple capability: Specified ripple currents at 120 Hz and 100 kHz give clear guidance for thermal and ripple-handling design margins.
• Secure screw-terminal connections: Screw terminals simplify installation and serviceability in industrial and power-electronics assemblies.
• Regulatory readiness: RoHS compliance supports use in lead-free manufacturing processes.
