LNC2W272MTEH

The LNC2W272MTEH is a screw-terminal aluminum electrolytic capacitor from Nichicon designed for industrial power systems. It provides 2700 µF capacitance at 450 V in a compact, stud-bolt mount package engineered for high-ripple, high-frequency applications.

Targeted for inverter circuitry and regenerative power environments, this capacitor combines a smaller footprint with elevated ripple-current capability and a rated load life of 5000 hours at 85°C, making it suitable for demanding industrial power supplies and motor-drive systems.

Key Features

• Capacitance & Rated Voltage — 2700 µF (2.7 mF) nominal capacitance with a 450 V rated voltage, specified with ±20% tolerance at 120 Hz, 20°C.
• Screw-terminal / Stud bolt mount — Radial can with screw terminals and stud bolt mounting for secure mechanical and electrical connection in high-current installations.
• High ripple-current capability — Specified ripple current of 13.7 A at 120 Hz and 19.18 A at 100 kHz to handle continuous and high-frequency load conditions.
• Endurance and load life — Rated for 5000 hours of ripple-current application at 85°C with performance limits defined for capacitance change, tan δ, and leakage current.
• Charge–discharge durability — Designed to withstand repetitive charge–discharge cycling testing (50 million cycles at ΔV = rated × 0.3, 3 Hz), maintaining capacitance, tan δ, and leakage within specified limits.
• Temperature range and stability — Operating range from −40°C to +85°C with defined impedance stability (Z(−40°C)/Z(+20°C) ≤ 8).
• Leakage current specification — After 5 minutes at rated voltage, leakage is limited to 3√(V) µA or 5 mA, whichever is smaller (at 20°C).
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact footprint — Smaller-sized with higher ripple capability compared to preceding LNX and LNK series, enabling space-efficient power-stage designs.

Typical Applications

• Industrial power supplies for inverter circuitry — Provides bulk energy storage and high-ripple tolerance for inverter DC-link filtering and smoothing tasks.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages and frequent charge–discharge cycles in motor-drive regenerative loops.
• General inverter systems — Suited for inverter front-ends requiring durable, high-voltage capacitors with reliable ripple performance.
• High-speed charge–discharge loads — Optimized for applications that subject capacitors to rapid energy exchange and repetitive cycling.

Unique Advantages

• High ripple handling with measured values — 13.7 A at 120 Hz and 19.18 A at 100 kHz provide quantifiable capability for both low- and high-frequency ripple environments.
• Compact, performance-focused design — Smaller-sized construction delivers higher ripple current than comparable LNX/LNK series parts, saving board or chassis space without sacrificing performance.
• Long operational life under ripple — 5000-hour load-life rating at 85°C under ripple current gives predictable aging and maintenance planning for industrial systems.
• Proven charge–discharge endurance — Validated to withstand aggressive repetitive cycling (50 million cycles), enhancing reliability in regenerative and pulsed-power systems.
• Secure mounting for heavy-current systems — Screw terminals and stud bolt mount ensure robust electrical and mechanical connections under vibration and thermal cycling.
• RoHS compliance — Meets applicable RoHS requirements for regulated materials.
