LNC2W182MSEG

The LNC2W182MSEG is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for industrial power electronics. It provides 1800 µF capacitance at a 450 V rating with polarized terminals and is optimized for inverter and regenerative power circuits.

Engineered for high-ripple, high-frequency environments, this LNC-series part delivers a smaller-sized solution with elevated ripple-current capability and a proven load life of 5000 hours at 85°C, making it suitable for industrial power supplies, AC servomotor regenerative circuits, and general inverter applications.

Key Features

• Capacitance & Voltage — Rated at 1.8 mF (1800 µF) and 450 V, with capacitance tolerance of ±20% (120 Hz, 20°C).
• High ripple-current capability — Specified ripple current of 11.9 A at 120 Hz and 16.66 A at 100 kHz to support high-frequency and regenerative loads.
• Temperature and lifetime — Operating range −40°C to +85°C with a load life of 5000 hours at 85°C under rated ripple-current conditions.
• Endurance and charge-discharge robustness — Designed to meet endurance requirements after DC bias plus rated ripple current for 5000 hours at 85°C; verified for 50 million charge-discharge cycles at room temperature (ΔV = rated voltage × 0.3, cycle 3 Hz).
• Leakage and insulation — Leakage current specification after 5 minutes: not more than 3√V (µA) or 5 mA (whichever is smaller) at 20°C; insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket.
• Mechanical & mounting — Screw terminal, radial can package suitable for secure mounting in industrial assemblies; compact footprint with dimensions L: 7.0 cm × D: 6.35 cm and polarized terminals.
• Safety margins — Voltage proof test: no abnormality at AC 2500 V for 1 minute between terminal and bracket; impedance stability down to −40°C (Z(−40°C)/Z(+20°C) ≤ 8).
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Bulk and smoothing capacitance for inverter front-ends where high DC voltage and sustained ripple current are required.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltage and rapid charge-discharge cycles encountered in motor drives.
• General inverter and motor drives — Energy storage and decoupling in high-power drive systems that demand durability at elevated temperatures.
• High-speed charge–discharge circuits — Suited for applications that require frequent or rapid cycling, supported by the specified charge-discharge endurance.

Unique Advantages

• Elevated ripple tolerance: Ripple-current ratings at both 120 Hz and 100 kHz (11.9 A and 16.66 A respectively) provide headroom for high-frequency and regenerative loads.
• Designed for long service under stress: 5000-hour load-life rating at 85°C under rated ripple conditions supports longevity in industrial environments.
• Charge-discharge durability: Qualification for 50 million charge-discharge cycles (ΔV = 0.3×Vrated) reduces maintenance risk in frequent-cycling applications.
• Compact, screw-terminal packaging: Radial can with screw terminals enables secure installation and reliable connections in power assemblies.
• Verified electrical integrity: Leakage current, insulation resistance, and voltage-proof test criteria are specified to ensure predictable behavior in high-voltage systems.
• RoHS compliant: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for material compliance.
