LNUN7152MSEGBB

The LNUN7152MSEGBB is a high-voltage aluminum electrolytic capacitor in a screw-terminal can designed for industrial power electronics. With a rated capacitance of 1500 µF and a maximum DC rating of 525 V, it is built for inverter and regenerative power applications that require high-voltage energy storage and fast charge–discharge handling.

Engineered for demanding environments, this screw-terminal LNU series part offers a smaller footprint than the LNT family, a 105°C maximum operating temperature, and a 5000-hour load life under rated ripple conditions—making it suitable for inverter circuitry, AC servomotor regenerative circuits and other industrial power supplies.

Key Features

• High Voltage Capability — Rated up to DC 525 V to support inverter and high-voltage power supply designs.
• Capacitance — 1.5 mF (1500 µF) nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C) for bulk energy storage and filtering.
• Screw Terminal Mounting — Radial can with screw terminals provides robust electrical and mechanical connections for industrial installations.
• Wide Temperature Range — Operates from −40°C to +105°C to meet elevated-temperature power system requirements.
• Long Load Life — 5000 hours endurance at 105°C with rated DC bias plus ripple current applied, maintaining capacitance and leakage within specified limits.
• High Ripple Current Handling — Specified ripple current of 7.2 A at 120 Hz and 10.08 A at 10 kHz for improved performance under AC ripple and high-frequency conditions.
• Charge–Discharge Endurance — Designed to withstand extensive charge–discharge cycling (50 million cycles per datasheet endurance test), suitable for regenerative and frequent switching applications.
• Leakage and Insulation Characteristics — Leakage current limited to 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes; insulation resistance ≥ 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 — Energy storage and smoothing in inverter front-ends and high-voltage power modules.
• AC Servomotor Drives — Regenerative circuits and DC bus stabilization for servo and motion-control systems.
• General Inverters — Bulk filtering and transient handling in inverter topologies used in industrial automation.
• High-Frequency Regenerative Circuits — Suited for applications requiring rapid charge–discharge cycles and high ripple-current endurance.

Unique Advantages

• High-voltage support up to 525 V: Enables use in high-voltage inverter and regenerative systems without series stacking of lower-voltage parts.
• Compact LNU form factor: Smaller sized than LNT-series equivalents, helping reduce enclosure space for power cabinets and modules.
• Robust thermal endurance: 5000-hour rated life at 105°C ensures sustained performance in hot industrial environments.
• High ripple-current capability: Rated ripple current at both low and high frequencies reduces heating and improves reliability in switching applications.
• Designed for frequent cycling: Endurance to extensive charge–discharge cycles supports regenerative and high-frequency power systems.
• Measured leakage and insulation specs: Clear limits for leakage current and ≥100 MΩ insulation resistance support dependable isolation and safety margins.
