LNC2V392MSEH

The LNC2V392MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, designed for high-ripple, high-duty industrial power applications. This radial, can-style capacitor delivers 3900 µF at 350 V with polarized screw terminals for secure, high-current connections.

Engineered for inverter circuitry and regenerative-voltage environments, the part combines elevated ripple-current capability with a 5000-hour endurance rating at 85°C to support continuous operation in demanding power-conversion systems.

Key Features

• Capacitance & Voltage — 3900 µF nominal capacitance at a rated voltage of 350 V, tolerance −20% to +20%.
• High Ripple-Current Capability — Low-frequency ripple current 14.3 A (120 Hz) and high-frequency ripple current 20.02 A (100 kHz) to handle heavy AC loading and switching environments.
• Endurance — Rated life of 5000 hours at 85°C under rated ripple current, supporting long-term continuous operation.
• Temperature Range — Operates from −40°C to +85°C for use across typical industrial ambient conditions.
• Low-Frequency Loss — Tangent of loss angle (tan δ) specified as 0.2 (measured at 20°C, 120 Hz), enabling predictable dissipation characteristics.
• Leakage Current — Specified leakage of 3500 µA to inform power-loss and hold-up calculations.
• Mechanical Package — Radial can with screw terminals (φ76.2 × 70 mm), designed for secure mounting and robust current handling.
• Compliance — RoHS-compliant material selection as specified by the LNC series documentation.

Typical Applications

• Industrial Power Supplies — Used in inverter and power-conversion rails where sustained ripple currents and reliable bulk capacitance are required.
• AC Servomotor Regenerative Systems — Supports high-frequency regenerative voltages and charge–discharge loading common in servo drives.
• General Inverter Systems — Suited for DC-link and energy-storage applications in general inverter topologies that demand high ripple handling and endurance.

Unique Advantages

• High Ripple Handling: Specified 14.3 A (120 Hz) and 20.02 A (100 kHz) ripple ratings let designers size DC-link and smoothing networks with confidence.
• Long Operational Life: 5000 hours at 85°C endurance under rated ripple current supports durability in continuous-duty industrial installations.
• Robust Temperature Tolerance: −40°C to +85°C operating range enables performance across a wide set of industrial ambient conditions.
• Secure Electrical Connections: Screw-terminal mounting simplifies high-current wiring and mechanical retention for rugged systems.
• Predictable Loss and Leakage: Specified tan δ and leakage current values allow accurate thermal and hold-up energy calculations.
• RoHS Compliance: Material compliance supports regulatory requirements for industrial equipment manufacturing.
