LNT2H471MSEFBB

The LNT2H471MSEFBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, specified for high-voltage, high-ripple applications. It delivers 470 µF capacitance at a 500 V rating with ±20% tolerance and is designed for general-purpose use where robust DC filtering and energy smoothing are required.

Built for elevated operating temperatures up to 105°C and a rated load life of 2000 hours at 105°C, this radial, can-style capacitor combines a compact φ51×80 mm envelope with screw terminals for secure, low-impedance connections in industrial and power-electronics assemblies.

Key Features

• High Voltage Capability: 500 V rated voltage suitable for high-voltage DC applications within the extended LNT range (10 V to 500 V).
• Capacitance & Tolerance: 470 µF with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and filtering performance.
• High Ripple Current: Rated ripple current of 3.2 A at 120 Hz and 4.48 A at 100 kHz to handle substantial AC components on DC rails.
• Thermal Endurance: Operating temperature range −25°C to +105°C (for 160–500 V parts) and load life of 2000 hours at 105°C under rated ripple and DC bias.
• Screw Terminal Mounting: Radial can with screw terminals (M5 for φ51) for secure, low-resistance connections and straightforward field wiring.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is limited to 3√(C×V) µA or 5 mA, whichever is smaller (at 20°C), supporting predictable maintenance intervals.
• RoHS Compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for regulated substance control.
• Packaging & Production: Supplied in cardboard packing and available in mass production quantities for volume designs.

Typical Applications

• High-voltage power supplies: DC bus filtering and smoothing where a 500 V-rated capacitor is required to control ripple and stabilize rails.
• Industrial power electronics: Energy buffering and decoupling in converters and inverters that demand high ripple tolerance and robust thermal performance.
• General-purpose energy storage: Bulk capacitance for systems needing compact, high-voltage capacitors with screw-terminal connections for reliable wiring.

Unique Advantages

• High-voltage, high-capacitance combination: 500 V and 470 µF in a compact φ51 can for applications that require both voltage withstand and substantial energy storage.
• Designed for elevated ripple and temperature: Specified ripple current at both low and high frequencies plus 105°C endurance for sustained performance in demanding environments.
• Secure, serviceable connections: Screw terminals enable low-impedance electrical contact and straightforward installation or field replacement.
• Predictable lifetime and reliability: Rated load life of 2000 hours at 105°C provides a defined endurance metric for design planning and maintenance scheduling.
• Regulatory compliance: RoHS conformity supports use in products requiring regulated-substance control.
