LNC2W182MSEGBB

The LNC2W182MSEGBB is a screw-terminal aluminum electrolytic capacitor designed for high-ripple, high-voltage applications. It combines a 1800 µF capacitance with a 450 V rating in a smaller-sized, radial can package for use where space and performance must be balanced.

Engineered for industrial power electronics, this part is suited to inverter circuitry, regenerative voltage circuits and high-frequency charge/discharge loads, offering a 5000 hour load life at 85°C and RoHS compliance.

Key Features

• Capacitance & Voltage — 1800 µF nominal capacitance with a 450 V rated voltage; capacitance tolerance is ±20% at 120 Hz, 20°C.
• High Ripple Current — Designed for heavy ripple environments with specified ripple current of 11.9 A at 120 Hz and 16.66 A at 100 kHz, supporting high-frequency regenerative and inverter applications.
• Screw-Terminal Package — Radial can with screw terminals provides a robust, serviceable electrical and mechanical connection for industrial mounting.
• Smaller Size — Marketed as a smaller-sized alternative within the series while maintaining high ripple capability; physical dimensions L: 7 cm × D: 6.35 cm.
• Operating Temperature & Lifetime — Rated for –40°C to +85°C with a load-life specification of 5000 hours at 85°C when subjected to rated ripple current and DC bias.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to the smaller of 3√V (µA) or 5 mA at 20°C, per the datasheet formula.
• Endurance & Charge/Discharge Durability — Endurance requirements include restoration to specified characteristics after 5000 hours at 85°C; series-level test includes 50 million charge-discharge cycles (ΔV = 0.3 × rated voltage, 3 Hz) at room temperature.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk and smoothing capacitor in inverter and converter front ends where sustained ripple handling and voltage rating are required.
• Motor Drives & Servo Inverters — Supports regenerative voltage and high-frequency switching loads in AC servomotor and general inverter systems.
• High-Frequency Charge/Discharge Circuits — Suited to applications that require rapid charge/discharge cycling due to specified endurance for repeated cycles.

Unique Advantages

• High ripple capability: Specified ripple currents at 120 Hz and 100 kHz enable reliable operation under demanding AC and switching loads.
• Compact radial screw-terminal package: Smaller-sized can with screw terminals simplifies installation and saves chassis space compared with larger alternatives.
• Long load life at elevated temperature: 5000 hours at 85°C under rated ripple current provides predictable lifetime for industrial deployments.
• Durability for cycling: Series-level validation includes extensive charge/discharge endurance testing to support repeated high-speed cycling applications.
• Clear leakage limits: Leakage current defined by a conservative formula (3√V µA or 5 mA max) supports predictable design margins for power systems.
• RoHS compliant: Meets current RoHS directive requirements for environmental regulatory coverage.
