LNC2W152MSEF

The LNC2W152MSEF is a screw-terminal aluminum electrolytic capacitor rated 1500 µF at 450 V, designed for industrial power systems. Its smaller-sized can and screw-terminal package deliver high ripple-current capability and robust performance in inverter and regenerative power applications.

Targeted for inverter circuitry and high-frequency regenerative voltages such as AC servomotors and general inverters, this capacitor combines high ripple handling, long load life and polarized, screw-terminal mounting for secure power-stage installations.

Key Features

• Capacitance & Voltage — 1.5 mF (1500 µF) rated at 450 V for bulk energy handling in high-voltage power stages.
• High ripple-current capability — Rated ripple current of 10.4 A at 120 Hz and 14.56 A at 100 kHz to support heavy AC ripple and high-frequency charge/discharge cycles.
• Screw-terminal package — Radial, can-style body with screw terminals for secure, low-impedance connections in industrial enclosures and bus assemblies.
• Temperature and lifetime — Operating range −40 °C to +85 °C with a specified load life of 5000 hours at 85 °C under rated ripple current and DC bias.
• Reliability tests — Endurance verified to meet capacitance, tan δ and leakage current criteria after 5000 hours at 85 °C; proven for charge–discharge endurance (50 million cycles at ΔV = rated voltage × 0.3, 3 Hz).
• Electrical safety characteristics — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• Size and mounting — Smaller-sized design compared to LNX/LNK series while delivering higher ripple current; package dimensions L: 9 cm × D: 5.1 cm for compact power assemblies.
• Environmental compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Bulk energy smoothing and ripple absorption in inverter DC links for motor drive and process-control systems.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages and repeated charge/discharge cycles in servo drives.
• High-frequency power electronics — Suited for designs requiring compact, high-ripple capacitors for switching supplies and DC bus filtering.

Unique Advantages

• High ripple tolerance: Rated ripple currents at both low and high frequencies (10.4 A at 120 Hz; 14.56 A at 100 kHz) reduce stress on the DC bus and support higher switching rates.
• Compact for its class: Smaller-sized can than comparable LNX/LNK types enables space savings in constrained power modules without sacrificing ripple performance.
• Robust endurance: 5000-hour load-life at 85 °C under rated ripple current ensures predictable aging and long-term capacitance stability in demanding environments.
• Screw-terminal mounting: Provides secure, low-resistance connections ideal for high-current power assemblies and repeatable field serviceability.
• Proven charge–discharge resilience: Validated for 50 million charge–discharge cycles (ΔV = 0.3 × Vr, 3 Hz), supporting applications with frequent energy reversals.
• RoHS compliant: Meets current RoHS requirements for environmentally regulated assemblies.
