LNC2H272MSEHBB

The LNC2H272MSEHBB is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNC series, designed for high-ripple, high-voltage applications. It delivers 2700 µF capacitance at a 500 V rating in a smaller-sized radial can with screw terminals, making it suitable for industrial power supplies and inverter circuitry.

Engineered for sustained operation at elevated temperatures, the part supports high-frequency regenerative voltages for AC servomotors and general inverter use, with RoHS compliance (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage – 2.7 mF (2700 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance for energy storage and DC bus smoothing.
• Package & Mounting – Radial can with screw terminals for secure electrical and mechanical connections; package dimensions L: 9 cm × D: 7.62 cm and seated height max 3.543 inch.
• Temperature Range & Lifetime – Operating range from −40 °C to +85 °C with a rated load life of 5000 hours at 85 °C under rated ripple current.
• High Ripple Current Capability – Rated ripple current of 15.8 A at 120 Hz and 22.12 A at 100 kHz to support high-speed charge–discharge cycles and demanding power electronics loads.
• Endurance & Charge–Discharge Resistance – Series-level endurance tested for 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz), maintaining capacitance, tan δ, and leakage within specified limits.
• Leakage & Insulation – Leakage current spec after 5 minutes is ≤ 3√V (µA) or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Regulatory – Compliant to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies – Bulk energy storage and DC bus support in inverter-fed industrial supplies where high ripple handling and long load life are required.
• Motor Drives & AC Servomotors – Use in high-frequency regenerative voltage environments to smooth DC link voltage and support frequent charge–discharge cycles.
• General Inverters – DC link and filtering duties in inverter circuitry for energy conversion and power conditioning.

Unique Advantages
