LNC2G103MSEHBB

The LNC2G103MSEHBB is a screw-terminal aluminum electrolytic capacitor designed for high-capacitance, high-voltage industrial applications. It delivers 10,000 µF at 400 V in a smaller-sized radial can with screw terminals, optimized for high ripple-current and high-frequency charge–discharge loading.

Typical target applications include industrial power supplies and inverter circuitry—especially systems requiring regenerative or high-frequency switching performance—where robust ripple handling, long life, and secure mechanical mounting are important.

Key Features

• Capacitance & Voltage: 10,000 µF (10 mF) rated at 400 V for high-energy bulk storage and smoothing in power systems.
• High ripple-current capability: 29.5 A at 120 Hz and 41.3 A at 100 kHz to support heavy AC ripple and high-frequency switching environments.
• Temperature & Lifetime: Operating range –40 °C to +85 °C with a load life of 5,000 hours at 85 °C when subjected to rated ripple current.
• Mounting & package: Screw terminal radial can (can with screw terminals) for secure bolted connections and easy installation in power racks and assemblies.
• Stability & endurance: Endurance requirements specify capacitance change within ±20%, tan δ within limits, and leakage current within initial specification after endurance testing.
• Leakage current: After 5 minutes at rated voltage, leakage current is not more than 3√(V) µA or 5 mA, whichever is smaller (measured at 20 °C).
• Polarized design & tolerance: Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20 °C.
• Compact footprint: Physical size listed as L: 16.5 × D: 7.62 cm with a maximum seated height of 6.496 inch for space-constrained power designs.
• RoHS compliant: Conforms to RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Industrial Inverters: Bulk energy storage and smoothing for inverter DC-link stages, where high ripple current and endurance at 85 °C are required.
• AC Servomotor Regeneration: Handling high-frequency regenerative voltages in servo drives and motion-control systems.
• High-frequency Power Supplies: Filtering and charge–discharge buffering in switching converters and high-speed power electronics.
• General-purpose Industrial Power: Robust DC bus and energy-storage use in industrial equipment that demands secure screw-terminal mounting and long operational life.

Unique Advantages

• High ripple capability: Explicit ripple ratings (29.5 A at 120 Hz, 41.3 A at 100 kHz) let designers size the DC-link and filter components with confidence for heavy AC and high-frequency loads.
• Smaller-sized package: Delivers 10,000 µF at 400 V in a reduced footprint compared to larger alternatives in the series, aiding denser power assemblies.
• Long rated life at elevated temperature: 5,000 hours at 85 °C under rated ripple current supports durable operation in industrial environments.
• Secure mechanical connection: Screw-terminal radial can package provides robust, vibration-resistant mounting for industrial racks and enclosures.
• Measurable leakage and endurance specs: Leakage current and endurance criteria are specified and tested, enabling predictable maintenance intervals and margin calculations.
• Regulatory compliance: RoHS conformity supports use in designs requiring restricted-substance compliance.
