LNC2W392MSEHBB

The LNC2W392MSEHBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series. It is a polarized, radial can capacitor optimized for high ripple handling and compact installation in industrial power electronics.

Designed for inverter circuitry and high-frequency regenerative applications, this 3.9 mF, 450 V unit combines high ripple-current capability, a robust 5,000 hour endurance at 85°C, and a wide operating temperature range of −40°C to +85°C to support demanding power-supply and motor-control systems.

Key Features

• High Capacitance and Voltage — 3.9 mF nominal capacitance at a rated voltage of 450 V, suitable for energy buffering and DC-link applications.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-impedance electrical and mechanical connections in power assemblies.
• High Ripple Current Capability — Low-frequency ripple handling of 17 A at 120 Hz and high-frequency ripple capability of 23.8 A at 100 kHz to accommodate heavy AC and switching currents.
• Endurance and Reliability — Load life rated 5,000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage current after endurance testing.
• Temperature Performance — Operates across −40°C to +85°C for broad industrial temperature requirements.
• Loss Tangent and Leakage — tan δ = 0.2 (measured at 20°C, 120 Hz) and a typical leakage current value of 3,970 μA.
• Physical and Packaging — Compact footprint with size φ76.2 × 90L (L: 9 cm × D: 7.62 cm); supplied in cardboard packing and available in mass-production quantities.

Typical Applications

• Industrial Inverters: DC-link and energy storage for inverter circuitry where high ripple current and long life at 85°C are required.
• AC Servomotor Regeneration: High-frequency regenerative circuits for servomotors and drives that demand robust charge–discharge handling.
• Power Supplies: Bulk smoothing and transient energy buffering in industrial power-supply designs with elevated switching frequencies.
• High-Speed Charge–Discharge Systems: Applications requiring repeated charge–discharge cycles, supported by endurance and charge–discharge qualifications.

Unique Advantages

• High Ripple Tolerance: Specifies both low-frequency (17 A at 120 Hz) and high-frequency (23.8 A at 100 kHz) ripple current ratings, enabling reliable performance across switching regimes.
• Long Operational Life: 5,000-hour endurance at 85°C under rated ripple and bias ensures predictable aging for industrial deployments.
• Wide Temperature Range: −40°C to +85°C operation supports installations in varied environmental conditions common to industrial equipment.
• Screw-Terminal Robustness: Screw-terminal mounting provides secure connections for high-current systems and simplifies assembly and maintenance.
• Clear Electrical Characterization: Specified tan δ (0.2 at 20°C, 120 Hz) and leakage current figures support accurate thermal and loss budgeting in designs.
• Series Proven Packaging and Marking: LNC-series construction and sleeve marking practices aid identification and handling in production environments.
