LNC2W822MTEJ

The LNC2W822MTEJ is an aluminum electrolytic, screw‑terminal capacitor in Nichicon’s LNC series designed for industrial power electronics. It delivers 8.2 mF capacitance at a 450 V rating in a compact, stud‑mount can optimized for high ripple and high‑speed charge/discharge loading.

Targeted at inverter circuitry, AC servomotor regenerative systems and industrial power supplies, the LNC2W822MTEJ combines high ripple current capability with a -40 °C to +85 °C operating range and a 5000‑hour load life at 85 °C for reliable performance in demanding regenerative and high‑frequency applications.

Key Features

• Capacitance & Voltage — 8.2 mF capacitance rated at 450 V for bulk energy storage in high‑voltage inverter and regenerative circuits.
• High Ripple Current — Supports 30.5 A at 120 Hz and 42.7 A at 100 kHz, enabling sustained performance under heavy AC ripple and high‑frequency switching conditions.
• Temperature & Lifetime — Operates from -40 °C to +85 °C with a rated load life of 5000 hours at 85 °C when ripple current is applied.
• Endurance and Charge‑Discharge Robustness — Meets endurance criteria after D.C. bias plus rated ripple current for 5000 hours; designed to withstand high‑speed charge/discharge cycles as described for the LNC series.
• Package & Mounting — Radial can with screw terminals and stud (bolt) mount for secure mechanical fastening and reliable electrical connection in industrial assemblies.
• Polarized, ±20% Tolerance — Polarized device with capacitance tolerance of -20% to +20% (±20% typical at 120 Hz, 20 °C).
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Leakage and Insulation — Leakage current specification and insulation resistance defined in the LNC series datasheet (leakage after 5 minutes not more than 3√V µA or 5 mA, whichever is smaller; IR >100 MΩ at DC 500 V between terminal and bracket).

Typical Applications

• Industrial Inverters — Bulk energy smoothing and ripple handling for inverter DC link capacitors in motor drives and variable frequency drives.
• Regenerative Power Systems — Handles high‑frequency regenerative voltages in AC servomotor and braking circuits where rapid charge/discharge is required.
• Industrial Power Supplies — Filtering and energy storage in high‑voltage industrial power supplies subjected to significant ripple current and switching stresses.

Unique Advantages

• High ripple capability at both low and high frequency: Rated ripple currents of 30.5 A (120 Hz) and 42.7 A (100 kHz) support designs with heavy AC ripple and high‑speed switching.
• Designed for rapid charge/discharge: Construction and series characteristics cope with high‑speed cycling typical in regenerative and inverter systems, improving system responsiveness.
• Long operational life at elevated temperature: 5000 hours load life at 85 °C under rated ripple current provides predictable aging and replacement planning.
• Secure mechanical mounting: Stud/bolt mount with screw terminals ensures robust installation in industrial enclosures and reduces risk of terminal loosening under vibration.
• Compact, series‑optimized form factor: LNC series offers smaller size with higher ripple capability compared to LNX and LNK series, aiding space‑constrained power assemblies.
• Regulatory compliance: RoHS conformity supports use in equipment requiring restricted‑substance compliance.
