LNC2W153MTEJ

The LNC2W153MTEJ is a screw-terminal, stud-mount aluminum electrolytic capacitor from Nichicon's LNC series. Designed for industrial power roles, it provides 15,000 µF capacitance at a 450 V rating in a radial can with screw terminals (φ90×215L / L: 21.5 × D: 9 cm).

Its specification set targets applications requiring high ripple-handling capability, robust charge–discharge endurance and long operational life at elevated temperatures, while maintaining RoHS compliance.

Key Features

• Capacitance & Voltage — 15,000 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (at 120 Hz, 20°C), providing bulk energy storage for power conversion and filtering.
• High Ripple Current — Rated ripple current of 43.1 A at 120 Hz and 60.34 A at 100 kHz, supporting high-frequency and high-current ripple environments.
• Thermal & Lifetime — Specified operating range of −40°C to +85°C with a rated load life of 5,000 hours at 85°C when subjected to rated ripple current.
• Mechanical & Mounting — Screw terminal, stud bolt mount configuration in a radial can package for secure electrical and mechanical connection in heavy-duty assemblies.
• Endurance & Charge–Discharge — Endurance criteria include D.C. bias plus rated ripple current for 5,000 hours at 85°C; charge–discharge endurance tested to 50 million cycles at room temperature (ΔV = rated voltage × 0.3, 3 Hz).
• Insulation & Voltage Proof — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket and no abnormality under AC 2500 V for 1 minute between terminal and bracket.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(V) µA or 5 mA, whichever is smaller (at 20°C), per the datasheet.
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters and Power Supplies — Bulk filtering and energy buffering for inverter circuitry where high ripple current and sustained operation at 85°C are required.
• AC Servomotor Regenerative Circuits — Supports high-frequency regenerative voltages and frequent charge–discharge cycles in motor drive systems.
• High-Frequency Switching Systems — Suited for applications with rapid charge/discharge behavior and high-frequency ripple up to 100 kHz.

Unique Advantages

• High ripple tolerance: Measured ripple currents of 43.1 A (120 Hz) and 60.34 A (100 kHz) enable handling of heavy AC ripple and high-frequency switching currents without compromise to performance.
• Long operational life at elevated temperature: Rated for 5,000 hours at 85°C under rated ripple, providing predictable lifetime behavior in demanding environments.
• Robust mechanical mounting: Screw terminal and stud bolt mount ensure secure electrical contact and mechanical stability in industrial assemblies.
• Validated charge–discharge endurance: Endurance to 50 million charge–discharge cycles (ΔV = 0.3 × Vr, 3 Hz) supports designs with frequent dynamic voltage swings.
• Safety margins for insulation and voltage proof: Insulation resistance and AC voltage proof tests between terminal and bracket provide measurable isolation characteristics for system integration.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for product builds and deployments.
