LNC2H152MSEG

The LNC2H152MSEG is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It provides 1500 µF capacitance at a 500 V rating in a radial can with screw terminals, optimized for inverter circuitry, high-frequency regenerative voltage and other industrial power-supply applications.

Engineered for elevated ripple handling and extended operating life, this capacitor supports high-speed charge–discharge loading and long-term use in demanding 85°C environments while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 1500 µF rated capacitance at 500 V, with capacitance tolerance of ±20% (–20% to +20%).
• Screw-terminal radial can — Robust screw-terminal mounting for secure high-current connections in industrial assemblies.
• High ripple-current performance — Rated ripple currents of 11.6 A at 120 Hz and 16.24 A at 100 kHz to support heavy AC ripple and regenerative loads.
• Operating temperature & lifetime — Category temperature range −40°C to +85°C with a load life of 5000 hours at 85°C when subjected to rated ripple current and DC bias.
• Charge–discharge endurance — Proven to withstand 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature while meeting post-test electrical limits.
• Electrical reliability — Leakage current after 5 minutes at 20°C limited to not more than 3√V µA or 5 mA (whichever is smaller); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• Compact footprint — Physical size L: 8.0 cm × D: 6.35 cm, offering a smaller-sized, higher-ripple-current form factor within the LNC series.
• Environmental compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Energy storage and smoothing for inverter circuitry in industrial drives and power systems.
• AC servomotor regenerative circuits — Handling high-frequency regenerative voltages and rapid energy transfer during motor braking and regeneration.
• High-speed charge–discharge systems — Suited for circuits that require fast charge and discharge cycles due to its charge–discharge endurance and ripple capability.
• General industrial power electronics — Bulk filtering and decoupling in heavy-duty power supplies where high voltage, ripple current and long life are required.

Unique Advantages

• High-voltage capability: 500 V rating enables use in medium-voltage industrial power designs without series stacking.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 100 kHz make selection and thermal planning straightforward for low- and high-frequency designs.
• Long-duration reliability: 5000-hour load life at 85°C under rated ripple and DC bias provides predictable aging and maintenance planning.
• Cycle durability: Qualification for 50 million charge–discharge cycles supports demanding, repetitive energy-transfer applications.
• Robust electrical safeguards: Defined leakage current limits, high insulation resistance and high-voltage proofing between terminal and bracket improve system safety and diagnostics.
• RoHS compliance: Meets current RoHS directives for environmentally regulated assemblies.
