LNC2V272MSEFBB

The LNC2V272MSEFBB is a screw‑terminal, aluminum electrolytic capacitor designed for industrial power applications. It provides 2.7 mF capacitance at 350 V with a polarized radial can and screw terminal mounting for robust electrical and mechanical connections.

Engineered for inverter and regenerative power circuits, this part delivers higher ripple current in a smaller package, supports high‑speed charge/discharge loading, and is rated for long operational life under elevated ripple stress (5000 hours at 85°C).

Key Features

• Capacitance & Voltage: 2.7 mF nominal capacitance at a 350 V rated voltage for energy storage in high‑voltage DC links.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low‑impedance connections suited to power assemblies and field wiring.
• High Ripple Current Capability: Rated ripple current 13.3 A at 120 Hz and 18.62 A at 100 kHz, enabling effective filtering and smoothing in high‑frequency inverter environments.
• Temperature & Lifetime: Operating range −40°C to +85°C with a load life of 5000 hours at 85°C when subjected to rated ripple current, supporting sustained operation in industrial equipment.
• Robust Endurance: Meets charge/discharge endurance requirements including verification after 50 million charge‑discharge cycles (ΔV = 0.3 × rated voltage, 3 Hz cycle) per the series specifications.
• Electrical Reliability: Leakage current limited to 3√V μA or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance ≥100 MΩ at DC 500 V between terminal and bracket; dielectric withstand AC 2500 V for 1 minute between terminal and bracket.
• Size & Form Factor: Compact radial can (L: 9.5 × D: 5.1 cm) that offers smaller sizing and higher ripple handling compared to related series, facilitating space‑constrained power designs.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies: Energy storage and smoothing in inverter DC links for motor drives and power conversion modules.
• AC Servomotor Systems: Handling regenerative and high‑frequency voltage stress in servo drive regenerative circuits.
