LNU2H152MSEFBN

The LNU2H152MSEFBN is an aluminum electrolytic, screw-terminal capacitor from Nichicon’s LNU series. It delivers 1500 µF capacitance at a 500 V DC rating and is designed for high-voltage industrial power applications that require compact form factor and high thermal endurance.

Engineered for inverter and regenerative circuits, this polarized radial can supports continuous operation from −40°C to 105°C, a rated ripple endurance and a 5000-hour load life at 105°C, making it suitable for demanding power-supply and motor-drive environments.

Key Features

• High Voltage Rating – Rated at 500 V DC with series capability up to DC 525 V, supporting high-voltage industrial power supplies and inverter circuitry.
• Large Capacitance – 1500 µF nominal capacitance (±20% tolerance) provides bulk energy storage and smoothing for power rails and regenerative stages.
• High Temperature Endurance – Rated for operation from −40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple conditions.
• High Ripple and HF Performance – Ripple current capability of 6.6 A at 120 Hz and 9.24 A at 10 kHz supports both low-frequency filtering and higher-frequency regenerative/charge-discharge loads.
• Screw Terminal, Radial Can – Robust screw-terminal mounting for secure electrical and mechanical connections in industrial assemblies; supplied with separate brackets for mounting.
• Compact Packaging – Designed as a high-voltage, smaller-sized option within the LNU series while maintaining high reliability for inverter and servo applications.
• Endurance and Charge–Discharge Reliability – Meets series endurance criteria including capacitance and leakage limits after 5000 hours at 105°C and charge–discharge endurance over 50 million cycles (3 Hz, ΔV = rated − 0.3 V).
• Leakage and Insulation Characteristics – Leakage current conforms to specified limits (not more than 3√CV µA or 5 mA after 5 minutes at 20°C) and insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliant – Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies – Bulk energy storage and smoothing in high-voltage supplies for inverters and power converters.
• Inverter and Motor-Drive Systems – Support for regenerative voltage and DC-link filtering in AC servomotor drives and general inverter designs.
• High-Frequency Regeneration – Handles high-frequency regenerative currents and repeated charge–discharge cycles in dynamic drive systems.
• High-Voltage Filtering – Filtering and decoupling in high-voltage sections where compact size and elevated temperature rating are required.

Unique Advantages

• High-voltage capability in a compact package: Rated to 500 V (series up to DC 525 V) with a smaller footprint than comparable LNT parts, enabling space-efficient high-voltage designs.
• Designed for elevated-temperature operation: 5000-hour load life at 105°C ensures predictable performance in hot industrial environments.
• Robust ripple handling: Specified ripple current at both 120 Hz and 10 kHz supports a broad range of filtering and regenerative loads.
• Long charge–discharge endurance: Verified to withstand extensive charge–discharge cycling, supporting frequent dynamic energy transfer in servo and inverter applications.
• Secure screw-terminal mounting: Radial can with screw terminals and supplied brackets provide reliable electrical connection and mechanical stability in field installations.
• Measured electrical reliability: Defined leakage, insulation resistance and voltage-proof characteristics give verifiable parameters for system design and qualification.
