LNC2W472MSEHBN

The LNC2W472MSEHBN is an aluminum electrolytic, screw-terminal capacitor designed for high-voltage industrial power applications. It delivers 4.7 mF (4700 µF) capacitance at a 450 V rating in a compact radial can with screw terminals, and is optimized for high ripple current and high-frequency regenerative environments.

Engineered for inverter circuitry, industrial power supplies and AC servomotor regenerative systems, the part offers a combination of high ripple handling, long load life and a broad operating temperature range for reliable performance in demanding systems.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with a 450 V rated voltage and ±20% tolerance for bulk energy storage and DC-link applications.
• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance connections in power assemblies and serviceable installations.
• High Ripple Current — Rated ripple current of 19.2 A at 120 Hz and 26.88 A at 100 kHz to support high-frequency and high-current ripple environments.
• Thermal and Lifetime Performance — Operates from −40 °C to +85 °C with a rated load life of 5000 hours at 85 °C under applied ripple current.
• Charge–Discharge Endurance — Designed to withstand charge–discharge cycling; specified endurance test of 50 million cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Leakage and Insulation Characteristics — Leakage current specified after 5 minutes as not more than 3√(V) µA or 5 mA (whichever is smaller); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand — Voltage proof performance verified with AC 2500 V applied for 1 minute between terminal and bracket.
• Compact Mechanical Footprint — Smaller-sized design in the LNC series (L: 11.5 × D: 7.62 cm) for space-conscious power modules; height seated max 4.528 inch.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and DC-link smoothing for high-voltage industrial converters and power distribution units.
• Inverter and Motor Drives — DC-link and regenerative energy buffering in general inverters and AC servomotor drive systems.
• Regenerative Circuits — High-frequency regenerative voltage handling for systems that recover energy during braking or bidirectional power flow.
• High-Speed Charge–Discharge Systems — Applications that require robust charge–discharge cycling endurance and reliable performance under frequent transitions.

Unique Advantages

• High ripple capability: Measured ripple currents of 19.2 A (120 Hz) and 26.88 A (100 kHz) enable use in high-current, high-frequency DC-link positions.
• Compact, serviceable screw-terminal form: Radial can with screw terminals provides a secure connection and easier field replacement compared with soldered packages.
• Long operational life under load: 5000 hours at 85 °C with rated ripple current offers predictable lifetime in continuous-duty industrial applications.
• Designed for charge–discharge durability: Specified endurance to 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) supports applications with frequent energy transfers.
• Robust electrical safety margins: Leakage, insulation resistance and voltage-withstand specifications reduce risk in high-voltage assemblies and simplify qualification testing.
• RoHS compliance: RoHS (2011/65/EU, (EU)2015/863) conformity supports deployments where restricted-substance compliance is required.
