LNC2G103MSEJBB

The LNC2G103MSEJBB is a screw-terminal aluminum electrolytic capacitor from Nichicon designed for high-energy storage and high-ripple applications. It delivers 10,000 µF at a 400 V rated voltage in a smaller-sized radial can with screw terminals, targeting industrial power electronics.

Engineered for inverter and motor-drive environments, this polarized capacitor supports high-frequency regenerative voltages and high-speed charge–discharge loading while meeting RoHS environmental requirements.

Key Features

• Capacitance & Voltage: 10,000 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current: Designed for high ripple handling—33.2 A at 120 Hz and 46.48 A at 100 kHz—suitable for demanding power-supply ripple environments.
• Temperature & Lifetime: Operating temperature range −40°C to +85°C with a rated load life of 5,000 hours at 85°C under rated ripple conditions.
• Package & Mounting: Radial can with screw terminals (screw terminal type) for secure mechanical and electrical installation in heavy-duty power assemblies.
• Reliability Characteristics: Endurance defined by capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value after 5,000 hours at 85°C with DC bias plus rated ripple.
• Leakage & Insulation: Leakage current after 5 minutes of rated voltage is limited to 3√V µA or 5 mA (whichever is smaller, at 20°C); insulation resistance is >100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand: No abnormality under AC 2,500 V applied for 1 minute between terminal and bracket.
• Polarized Design: Polarized construction for DC link, inverter, and regenerative circuits where polarity is defined.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Energy storage and smoothing for inverter circuitry in industrial power-supply designs.
• AC Servo and Motor Drives: Handling high-frequency regenerative voltages and rapid charge–discharge events in motor-control systems.
• General Inverters: Bulk capacitance and ripple management in inverter stages and DC-link circuits.

Unique Advantages

• High Ripple Capability: Supports large ripple currents (33.2 A at 120 Hz; 46.48 A at 100 kHz), reducing thermal stress in heavy-duty power electronics.
• Compact High-Energy Storage: 10,000 µF at 400 V in a smaller-sized screw-terminal can provides substantial energy density for tight layouts.
• Designed for Harsh Duty Cycles: 5,000-hour load life at 85°C with defined endurance limits ensures predictable performance over extended operation.
• Robust Electrical Isolation: High insulation resistance (>100 MΩ at DC 500 V) and AC 2,500 V dielectric proof between terminal and bracket improve assembly safety margins.
• Secure Mechanical Mounting: Screw-terminal, radial-can construction simplifies installation and provides durable electrical connections in heavy-current applications.
• Regulatory Compliance: RoHS conformity supports deployments where restricted-substance compliance is required.
