LNC2W152MSEFBB

The LNC2W152MSEFBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-ripple, high-frequency industrial power applications. It provides 1500 µF nominal capacitance at a 450 V rating, optimized for inverter circuitry, regenerative drives, and other power-supply tasks that demand robust charge–discharge handling.

Built for sustained operation, the capacitor is rated for operation from −40 °C to +85 °C with a specified 5000-hour load life at 85 °C under rated ripple current, and it is RoHS compliant.

Key Features

• Capacitance & Voltage — 1500 µF nominal capacitance with a 450 V rated voltage; capacitance tolerance ±20% (at 120 Hz, 20 °C).
• Screw-terminal radial can — Robust screw terminal mounting and radial can package for secure mechanical and electrical connections in power assemblies.
• High ripple current capability — Rated ripple current: 10.4 A at 120 Hz and 14.56 A at 100 kHz, enabling handling of both low- and high-frequency stress in power circuits.
• Wide temperature range and endurance — Operates from −40 °C to +85 °C with a load-life rating of 5000 hours at 85 °C when subjected to DC bias plus rated ripple current.
• Charge–discharge durability — Meets endurance requirements after 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz), supporting high-speed switching and regenerative applications.
• Leakage current specification — After 5 minutes at rated voltage, leakage current is not more than 3√(V) μA or 5 mA, whichever is smaller (measured at 20 °C).
• Insulation and voltage proof — Insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• Physical size & construction — Compact form with dimensions L: 9 cm × D: 5.1 cm, polarized construction, and white-on-black sleeve marking for part identification.

Typical Applications

• Industrial Inverter Power Supplies — Energy storage and smoothing in inverter front-ends where high DC voltage and sustained ripple handling are required.
• AC Servomotor Regenerative Circuits — Handling high-frequency regenerative voltages and rapid charge–discharge events in motor drive systems.
• General Motor Drives and Power Electronics — Bulk capacitance for buffering, surge absorption, and decoupling in general inverter and drive applications.

Unique Advantages

• High ripple handling in a smaller package: Combines elevated ripple-current ratings with a compact radial can footprint to help reduce overall assembly size.
• Long-term load life under ripple: 5000-hour rated life at 85 °C under DC bias plus rated ripple current provides predictable performance in continuous-duty environments.
• High-frequency capability: Ripple rating at 100 kHz and validated charge–discharge endurance support high-speed switching and regenerative operating modes.
• Defined leakage and insulation performance: Clear leakage current limits and >100 MΩ insulation resistance at DC 500 V support reliable system integration and safety checks.
• Robust electrical isolation proof: AC 2500 V, 1-minute voltage proof between terminal and bracket ensures dielectric integrity for assembly and test.
• RoHS compliant: Meets RoHS directives for restricted substances, supporting regulatory compliance in product builds.
