LNC2G332MSEHBN

The LNC2G332MSEHBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNC series, rated 3300 µF at 400 V. It is designed as a smaller-sized, high-ripple-current solution for industrial power electronics where robust bulk energy storage and high-frequency charge–discharge capability are required.

Typical use cases include industrial power supplies and inverter circuitry, including high-frequency regenerative voltage applications for AC servomotors and general inverters. The part is polarized, RoHS compliant, and specified for operation from −40 °C to +85 °C with a rated load life of 5000 hours at 85 °C.

Key Features

• Capacitance & Voltage: 3300 µF nominal capacitance at a rated voltage of 400 V, with capacitance tolerance of ±20% (120 Hz, 20 °C).
• Screw Terminal Package: Radial can package with screw terminals for secure bolted connections in high-current power systems and inverter assemblies.
• High Ripple Current: Rated ripple current of 15.3 A at 120 Hz and 21.42 A at 100 kHz, supporting demanding AC ripple and high-frequency regenerative loads.
• Temperature & Lifetime: Operating temperature range −40 °C to +85 °C and load life specified as 5000 hours at 85 °C under rated ripple conditions.
• Leakage Current Specification: 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).
• Endurance & Charge–Discharge Durability: Designed to meet endurance criteria after 5000 hours at 85 °C and to withstand charge–discharge testing (50 million cycles, ΔV = rated × 0.3, 3 Hz) with defined limits on capacitance change, tan δ, and leakage current.
• Compact Footprint: Smaller-sized design compared with related LNX and LNK series parts while maintaining higher ripple capability; physical size approximately L: 7 cm × D: 7.62 cm for system layout planning.
• Regulatory Compliance: Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing in inverter-fed power supplies that require sustained ripple handling and long life at elevated temperatures.
• Inverter and Motor Drive Circuits: Energy buffering and regenerative voltage handling for AC servomotor drives and general inverter systems operating at high switching frequencies.
• High-Frequency Regeneration: Applications needing robust performance under high-speed charge–discharge cycles and high-frequency ripple environments.

Unique Advantages

• High Ripple Handling: Specified ripple current values at both 120 Hz and 100 kHz enable reliable operation in both low- and high-frequency inverter environments.
• Smaller Physical Size for Given Performance: Offers a reduced footprint compared with select LNC family predecessors while delivering elevated ripple capability, aiding compact power module designs.
• Long Operational Life at Elevated Temperature: 5000-hour load life specification at 85 °C provides predictable longevity for industrial applications.
• Durability to Repeated Cycling: Designed and tested for extensive charge–discharge cycles (50 million cycles at defined test conditions), supporting high-speed regenerative duty.
• Secure Mechanical Termination: Screw terminals provide robust, low-resistance connections suited to high-current bus arrangements and field serviceability.
• Standards-Conscious Manufacture: RoHS compliance supports regulatory requirements for industrial equipment deployment.
