LNC2V472MSEGBN

The LNC2V472MSEGBN is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It delivers high ripple-current capability in a smaller-sized package within the LNC series architecture, making it suitable for inverter circuitry and regenerative power applications.

Targeted at industrial power supplies, AC servomotor inverters and high-speed charge–discharge loads, this polarized capacitor offers a 350 V rating, 4.7 mF capacitance and a robust 5,000 hour load life at 85°C. The part is RoHS compliant.

Key Features

• High ripple-current capability — Rated ripple current: 16.4 A at 120 Hz and 22.96 A at 100 kHz, supporting heavy AC ripple and high-frequency loading.
• Rated voltage and capacitance — 350 V nominal voltage with 4.7 mF capacitance and ±20% tolerance for bulk energy storage and smoothing.
• Screw terminal mounting — Radial can with screw terminals provides secure mechanical and electrical connections for power assemblies.
• Wide operating temperature — Specified for −40°C to +85°C operation to match industrial temperature ranges.
• Long load life — Endurance specified as 5,000 hours with rated ripple current at 85°C for reliable field lifetime under continuous ripple stress.
• Charge–discharge endurance — Designed to withstand charge–discharge cycling (50 million cycles specified for series) to handle high-speed regenerative and switching conditions.
• Leakage and insulation — Leakage current limited to 3√V μA (or 5 mA max) after 5 minutes at rated voltage; insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket.
• Voltage proof — Withstands AC 2500 V for 1 minute between terminal and bracket without abnormality, supporting safe isolation verification.

Typical Applications

• Industrial inverters — Bulk and filtering capacitor in inverter DC link circuits where high ripple current and long life are required.
• AC servomotor regenerative circuits — Energy buffering and smoothing for high-frequency regenerative voltages in motor drives.
• Power supplies for industrial equipment — Input/output smoothing and bulk energy storage in industrial power converters and UPS systems.
• High-speed charge–discharge systems — Applications that require repeated rapid charge/discharge cycles benefit from the part’s specified endurance.

Unique Advantages

• High ripple handling in a compact form — Delivers substantial ripple current (16.4 A @120 Hz, 22.96 A @100 kHz) while maintaining a smaller footprint compared with earlier LNX/LNK series designs.
• Robust lifetime under stress — 5,000 hour load-life rating at 85°C with rated ripple current provides predictable performance in continuous-duty power applications.
• Screw-terminal reliability — Secure screw-terminal connections simplify installation and improve electrical contact in high-current assemblies.
• Designed for high-frequency regeneration — Specified charge–discharge endurance supports use in regenerative and switching-heavy systems.
• Measured insulation and leakage specifications — Clear leakage current limits and insulation resistance requirements support verification and system safety checks.
