LNUN7152MSEG

The LNUN7152MSEG is a high-voltage, screw-terminal aluminum electrolytic capacitor from Nichicon's LNU series. Designed for demanding industrial power applications, it delivers a compact, high-voltage solution with robust thermal and electrical endurance.

With a 525 VDC rating, 1.5 mF capacitance and a load life specified at 5000 hours at 105°C, this capacitor is targeted for inverter circuitry, regenerative voltage handling in AC servomotor systems and other industrial power-supply tasks that require high-frequency charge–discharge capability and long-term reliability.

Key Features

• High voltage rating — Rated up to DC 525 V to support high-voltage industrial power supplies and inverter circuitry.
• Capacitance — 1.5 mF (1,500 μF) nominal capacitance with ±20% tolerance (120 Hz, 20°C) for stable energy storage.
• Screw terminal radial can — Radial, can-style package with screw terminals for secure, low-resistance connections in power assemblies.
• Wide operating temperature — Specified for –40°C to +105°C operation, enabling use in high-temperature industrial environments.
• High ripple handling — Rated ripple current of 7.2 A at 120 Hz and 10.08 A at 10 kHz for low-frequency and high-frequency applications respectively.
• Long load life and endurance — 5000 hours endurance at 105°C with D.C. bias plus rated ripple current; supports charge–discharge endurance tests described in the series datasheet.
• Leakage and reliability characteristics — Leakage current limited per datasheet formula (after 5 minutes, not more than 3√CV μA or 5 mA, whichever is smaller) and insulation resistance of more than 100 MΩ at DC 500 V between terminal and bracket.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact dimensions — Smaller sized than the LNT series with dimensions L: 9.5 × D: 6.35 cm and a maximum seated height of 3.74 inch, enabling denser power module layouts.

Typical Applications

• Industrial inverter power supplies — Energy buffering and DC-link filtering in inverter circuitry for industrial drives.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages and rapid charge–discharge cycles in servo drives.
• General motor control and drive systems — Suited for inverter-based motor controllers and other high-voltage power-electronics subsystems.
• High-frequency charge–discharge applications — Designed to cope with repeated high-speed charge–discharge loading environments.

Unique Advantages

• High-voltage capability: 525 VDC rating enables integration into high-voltage power systems without oversized solutions.
• Thermal endurance at elevated temperature: 5000-hour load life at 105°C provides predictable ageing characteristics for long-term industrial use.
• Dual-frequency ripple performance: Specified ripple currents at both 120 Hz and 10 kHz support designs that face mixed-frequency stressors.
• Robust connection method: Screw terminal package ensures secure mechanical and electrical connections in high-current assemblies.
• Compact footprint: Smaller sizing than comparable LNT parts helps reduce PCB or module area in constrained power assemblies.
• Tested charge–discharge endurance: Series-level specifications include extensive charge–discharge cycling to validate behavior under repetitive switching conditions.
