LNC2W682MSEJBB

The LNC2W682MSEJBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power electronics. It delivers 6.8 mF (6800 µF) capacitance at a 450 V rating and is optimized for high ripple-current and high-speed charge–discharge environments.

Targeted at inverter circuitry, regenerative servo drives and general inverter applications, this capacitor combines a compact footprint with high ripple-current capability and a specified 5000-hour load life at 85°C for robust performance in demanding power-supply designs.

Key Features

• Capacitance and Voltage: 6.8 mF (6800 µF) rated at 450 V for bulk energy storage and DC-link applications.
• High ripple-current handling: Specified ripple current of 27.5 A at 120 Hz and 38.5 A at 100 kHz to support high-frequency inverter and regenerative circuits.
• Temperature and lifetime: Operating range –40°C to +85°C with a rated load life of 5000 hours when subjected to DC bias plus rated ripple current at 85°C.
• Screw-terminal mounting: Radial, can-style package with screw terminals for secure electrical and mechanical connection in power assemblies.
• Durability under cycling: Meets charge–discharge endurance: after 50 million cycles (ΔV = rated × 0.3 at 3 Hz) the capacitor remains within specified limits for capacitance, tan δ and leakage current.
• 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).
• Polarized design: Polarized aluminum electrolytic construction for DC-link and energy-storage use.
• RoHS compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: Used as DC-link and bulk energy storage in inverter and converter power stages to smooth DC rails and support transient loads.
• AC servomotor regenerative systems: Suited for high-frequency regenerative voltage applications where frequent charge–discharge cycles and high ripple currents occur.
• General inverter systems: Provides high-capacitance energy buffering and ripple current tolerance for motor drives and variable-speed drives.

Unique Advantages

• High ripple-current capability: Rated ripple currents at both low and high frequencies (27.5 A @120 Hz, 38.5 A @100 kHz) enable reliable operation in high-frequency power circuits.
• Compact, high-performance form: Described as smaller-sized with higher ripple current compared to earlier LNX/LNK series variants, offering space-efficient energy storage.
• Proven endurance: Designed for 5000 hours of DC bias plus rated ripple current at 85°C with limits on capacitance change, tan δ and leakage current to maintain long-term performance.
• Robust electrical isolation and voltage proof: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and no abnormality under AC 2500 V for 1 minute.
• Charge–discharge resilience: Validated for 50 million charge–discharge cycles (ΔV = rated × 0.3 at 3 Hz) with maintained electrical characteristics, supporting frequent transient loading.
• Regulatory compliance: RoHS directive compliance supports deployment in regulated industrial environments.
