LNC2W682MSEH

The LNC2W682MSEH is a screw‑terminal aluminum electrolytic capacitor designed for industrial power applications. It is a radial, can‑style, polarized capacitor offering 6.8 mF capacitance at a 450 V rating and a compact φ76.2 × 145 mm form factor.

Engineered for inverter circuitry, regenerative drives and other high‑stress power electronics, the LNC2W682MSEH delivers high ripple handling and long load life performance while meeting RoHS requirements.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) nominal capacitance with a 450 V rated voltage and a ±20% tolerance for energy storage and smoothing in high‑voltage power rails.
• High Ripple Current Capability: Rated ripple current of 23.8 A at 120 Hz (low frequency) and 33.32 A at 100 kHz (high frequency) to support heavy AC and high‑frequency charge/discharge loading.
• Robust Endurance: Load life of 5000 hours at 85°C when DC bias plus rated ripple current is applied; capacitance change and dissipation factor maintained per endurance criteria.
• Temperature Range: Rated for –40°C to +85°C operation, suitable for a wide range of industrial ambient conditions.
• Mechanical & Mounting: Screw terminal mounting in a radial, can package (φ76.2 × 145 mm), enabling secure, low‑inductance connections for high‑current systems.
• Leakage & Insulation: Leakage current specified up to 5000 µA (5 mA) and insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Durability Under Cycling: Designed to withstand high‑speed charge/discharge conditions and long charge‑discharge endurance testing as specified in the product datasheet.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Energy smoothing and bulk storage for inverter front‑ends and industrial DC bus systems.
• Motor Drives & Regenerative Circuits: Handling high‑frequency regenerative voltages for AC servomotors and inverter drives.
• High‑Frequency Charge/Discharge Systems: Suitable where rapid charge/discharge cycles and high ripple currents are expected.
• General Purpose Power Electronics: Bulk energy storage and filtering in high‑voltage industrial applications requiring a robust, screw‑terminal capacitor.

Unique Advantages

• High‑Voltage Energy Storage: 450 V rating with 6.8 mF capacitance provides substantial energy buffering for high‑voltage power rails.
• Exceptional Ripple Handling: High ripple current ratings at both low and high frequencies reduce thermal stress under heavy AC and switching loads.
• Long Operational Life: 5000 hours rated life at 85°C under rated ripple current supports extended maintenance intervals in industrial systems.
• Compact Screw‑Terminal Package: Radial can with screw terminals enables secure, low‑impedance connections for power electronics while minimizing footprint for its performance class.
• Designed for Charge‑Discharge Robustness: Built to cope with high‑speed charge/discharge cycles and repeated cycling endurance as specified in the datasheet.
• RoHS Compliance: Meets RoHS directive requirements for restricted substances.
