LNU2H102MTEF

The LNU2H102MTEF is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNU series, specified for high-voltage industrial power electronics. It delivers 1000 µF capacitance at a 500 V rated voltage and is optimized for inverter and regenerative power circuits that require high-frequency charge/discharge performance.

Designed for demanding thermal and electrical environments, the LNU2H102MTEF offers 105°C operation, a 5000-hour load life under rated ripple current, and construction suited to high-frequency regenerative voltages in AC servomotor and general inverter applications.

Key Features

• Capacitance & Voltage: 1000 µF nominal capacitance at a 500 V rated voltage, with ±20% tolerance (120 Hz, 20°C).
• 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 current.
• Ripple current capability: Handles 5 A at 120 Hz and 7 A at 10 kHz, supporting high-frequency power applications.
• Robust charge–discharge endurance: Qualified for charge–discharge endurance up to 50 million cycles (ΔV = rated voltage ±0.3, 3 Hz) per series specifications.
• Leakage current specification: After 5 minutes at rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C).
• Insulation and voltage proof: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute without abnormality.
• Package & mounting: Screw terminal (stud bolt mount) can-style radial package with nominal dimensions L: 9 cm × D: 5.1 cm, suitable for robust mechanical attachment.
• Regulatory compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: Energy storage and smoothing in inverter front-ends where high DC voltage and sustained ripple handling are required.
• AC servomotor regenerative circuits: Absorbing and supplying regenerative energy during motor braking and transient events at high frequency.
• High-frequency charge–discharge systems: Applications that require fast charge/discharge cycles and long cycle endurance, including power-conditioning modules.
• General industrial power electronics: Bulk capacitance for rectifier and DC bus circuits in industrial drives and power distribution equipment.

Unique Advantages

• High-voltage capability: 500 V nominal rating (series rated up to DC525 V) enables use in high-voltage DC bus designs.
• Compact high-voltage form factor: LNU series provides a smaller footprint compared with certain other high-voltage can types, aiding space-constrained designs.
• Long-term thermal reliability: 5000-hour load life at 105°C ensures predictable performance in hot operating environments.
• Superior ripple and HF performance: Specified ripple current at both low (120 Hz) and high (10 kHz) frequencies supports stable DC bus operation under varying switching conditions.
• Durable electrical endurance: Proven charge–discharge endurance (50 million cycles per series data) supports regenerative and repeated transient duty.
• Regulatory readiness: RoHS compliance simplifies integration into products targeting global markets constrained by restriction of hazardous substances.
