LNC2W392MTEH

The LNC2W392MTEH is a screw‑terminal aluminum electrolytic capacitor designed for industrial power electronics. It is a polarized, stud‑mount radial can intended for high‑ripple, high‑frequency applications in inverter and regenerative circuits.

Engineered for continuous operation up to 85°C with a rated voltage of 450 V and a capacitance of 3.9 mF, this part delivers high ripple current capability and long load life for demanding power‑supply and motor‑drive environments.

Key Features

• Rated Performance — 3.9 mF capacitance at 450 V, providing bulk energy storage for inverter and regenerative circuits.
• High Ripple Current — Rated ripple current of 17 A at 120 Hz and 23.8 A at 100 kHz to support high‑frequency charge/discharge and regenerative loads.
• Temperature Range & Lifetime — Operational from −40°C to +85°C with a load life specified as 5000 hours at 85°C under rated ripple conditions.
• Mechanical & Mounting — Stud bolt mount with screw terminals in a radial can package for robust panel or bracket installation; physical footprint L: 9 cm × D: 7.62 cm.
• Electrical Reliability — Capacitance tolerance ±20%; leakage current specified as not more than 3√(V) μA or 5 mA (whichever is smaller) after 5 minutes at rated voltage.
• Endurance & Charge‑Discharge Robustness — Designed to meet endurance criteria after DC bias plus rated ripple current for 5000 hours at 85°C and to withstand 50 million charge/discharge cycles at room temperature (ΔV = rated × 0.3, 3 Hz).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for inverter front ends and industrial DC link stages.
• AC Servomotor Regeneration — Handles high‑frequency regenerative voltage and rapid charge/discharge in motor drive regenerative circuits.
• General Inverters — Supports high ripple current and high‑speed switching environments common in general inverter designs.
• High‑Speed Charge/Discharge Systems — Suitable where repeated rapid energy transfer is required, backed by charge/discharge endurance testing.

Unique Advantages

• High ripple capability at frequency — 23.8 A at 100 kHz and 17 A at 120 Hz support high‑frequency inverter and regenerative loads without excessive heating.
• Smaller footprint for equivalent performance — Designed to be smaller sized while delivering higher ripple current compared to earlier LNX/LNK series, aiding space‑constrained layouts.
• Long load life at elevated temperature — 5000 hours at 85°C under rated ripple current provides predictable long‑term behavior in industrial environments.
• Proven charge/discharge endurance — Validated for 50 million charge/discharge cycles (ΔV = rated × 0.3), demonstrating suitability for high duty‑cycle regenerative applications.
• Robust electrical safeguards — Leakage and insulation characteristics are specified to ensure controlled behavior after voltage application and between terminals and bracket.
• RoHS compliance — Meets current RoHS requirements for restricted substances.
