LNU2H152MSEFBB

The LNU2H152MSEFBB is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNU series, rated 1.5 mF (1500 µF) at 500 V DC. Designed for industrial power applications, this polarized radial can delivers high-voltage capability in a compact screw-terminal package for inverter circuitry and regenerative power systems.

Built for demanding environments, the capacitor supports a wide operating temperature range and long load life under ripple conditions, providing stable bulk energy storage for inverter and motor-drive architectures.

Key Features

• Capacitance and Voltage — 1.5 mF (1500 µF) nominal capacitance with a 500 V rated voltage; capacitance tolerance ±20% (120 Hz, 20°C).
• High-temperature endurance — Rated for continuous operation from −40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple current.
• High ripple capability — Ripple current ratings of 6.6 A at 120 Hz and 9.24 A at 10 kHz support high-frequency and low-frequency ripple environments.
• Screw-terminal radial can — Robust screw terminal mounting (radial, can with screw terminals) for secure connections in industrial assemblies; nominal bolt diameter M5 (series drawing information).
• Leakage and insulation — After 5 minutes at rated voltage and 20°C, leakage current is limited to 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Endurance and stability — Endurance characteristics: after 5000 hours at 105°C with DC bias plus rated ripple current, capacitance remains within 90% ±20% of initial, tan δ ≤ 200% of initial spec, and leakage current ≤ initial specified value. Series is also tested for long-term charge–discharge endurance (50 million cycles).
• RoHS compliant — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Bulk energy storage and ripple smoothing in inverter DC-link circuits for motor drives and industrial converters.
• AC servomotor regenerative systems — Handles high-frequency regenerative voltages and high-speed charge–discharge loading in servo and motion-control systems.
• High-voltage power electronics — Filtering and energy buffering in high-voltage DC systems where compact high-voltage capacitors are required.

Unique Advantages

• High-voltage in a compact package — 500 V rating (series up to 525 V) provides high-voltage capability while maintaining a smaller footprint compared with some other high-voltage designs.
• Designed for sustained ripple loading — Rated ripple currents at both low and high frequencies allow reliable operation in mixed-frequency power environments.
• Long load life at elevated temperature — 5000-hour life at 105°C under rated ripple conditions supports extended service life in industrial installations.
• Robust mechanical termination — Screw-terminal radial can and M5 nominal bolt diameter enable secure electrical and mechanical connections for heavy-current applications.
• Verified insulation and voltage withstand — Insulation resistance >100 MΩ and AC 2500 V 1-minute voltage proof between terminal and bracket ensure electrical integrity in high-voltage assemblies.
