LNC2W272MSEH

The LNC2W272MSEH is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It delivers 2.7 mF (2700 µF) at a 450 V rating in a compact, radial can with screw terminals, optimized for high ripple and high-frequency charge–discharge conditions.

Engineered for inverter circuitry and regenerative motor drives, this Nichicon LNC-series unit offers a smaller footprint with higher ripple-current capability, a 5000-hour load-life at 85°C under ripple application, and RoHS compliance for industrial power-supply designs.

Key Features

• Capacitance and Voltage: 2.7 mF (2700 µF) rated at 450 V for energy storage and DC-link smoothing in power electronics.
• Screw-Terminal Package: Radial can with screw terminals provides secure, low-inductance connections for high-current systems.
• High Ripple-Current Capability: Rated ripple current of 13.7 A at 120 Hz and 19.18 A at 100 kHz supports heavy AC and high-frequency regenerative loads.
• Temperature and Lifetime: Operates from –40°C to +85°C with an endurance of 5000 hours at 85°C under rated ripple-current conditions.
• Smaller-Sized Design: Specified as a smaller-sized, higher-ripple-current option within the LNC series, offering space savings compared with LNX/LNK variants.
• Durability and Charge–Discharge Endurance: Meets specified characteristics after 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz), supporting applications with frequent switching stress.
• Polarized, Tight Tolerance: Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20°C.
• Leakage and Insulation Specs: Leakage current after 5 minutes is ≤ 3√V µA or 5 mA (whichever smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies: Bulk energy storage and DC-link smoothing for general inverter modules where high ripple and long life are required.
• AC Servomotor Drives: Handles high-frequency regenerative voltages and fast charge–discharge cycles in servo and motion-control systems.
• Regenerative Braking Systems: Absorbs and smooths returned energy in high-speed charge–discharge environments.
• High-Frequency Power Electronics: Suitable for circuits that require robust high-frequency ripple performance up to 100 kHz.

Unique Advantages

• High ripple handling: Clearly specified ripple current ratings at 120 Hz and 100 kHz allow designers to size DC-link and smoothing capacitors with confidence.
• Compact, screw-terminal form-factor: Smaller-sized LNC series design reduces enclosure footprint while providing secure screw-terminal connections for power assemblies.
• Proven endurance at elevated temperature: 5000-hour load life at 85°C under ripple conditions demonstrates long-term stability for continuous industrial operation.
• High-frequency durability: Endurance to 50 million charge–discharge cycles supports designs with frequent switching and regenerative events.
• Robust electrical integrity: Tight leakage, insulation resistance, and voltage-proof specifications reduce risk in high-voltage assemblies.
• Regulatory readiness: RoHS compliance simplifies environmental and procurement considerations for industrial equipment.
