LNC2W222MSEH

The LNC2W222MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, rated 2.2 mF at 450 V. It is a radial can with screw terminals designed for industrial power electronics where high ripple handling and robust terminal connections are required.

This part is optimized for inverter-style power supplies and high-frequency regenerative circuits, offering a wide operating temperature range and a specified load life under ripple conditions at elevated temperature.

Key Features

• Capacitance and Voltage – 2.2 mF rated capacitance at 450 V for bulk energy storage and smoothing in high-voltage circuits.
• High Ripple Current – Rated ripple current of 12.5 A at 120 Hz and 17.5 A at 100 kHz to support high-frequency and high-current charge/discharge cycles.
• Screw Terminal Mounting – Radial can with screw terminals for secure, low-resistance connections in industrial assemblies.
• Operating Temperature and Lifetime – Specified for –40 °C to +85 °C with a rated load life of 5000 hours at 85 °C with applied ripple current.
• Polarized Design – Intended for DC applications where polarized electrolytic capacitors are required.
• Compact Footprint – Physical dimensions L: 6.5 × D: 7.62 cm, offering a smaller-sized option within the LNC family while maintaining high ripple capability.
• Leakage and Insulation Characteristics – Leakage current limited per datasheet (after 5 minutes at rated voltage: ≤ 3√V μA or 5 mA, whichever is smaller) and insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliant – Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies (Inverter Circuitry) – Bulk energy storage and ripple handling for inverter front-ends and DC link smoothing in industrial drives.
• AC Servo Motor Drives – Supports high-frequency regenerative voltage and rapid charge/discharge cycles in servo systems.
• General Inverters – Energy buffering and ripple absorption in general-purpose inverter designs for industrial equipment.
• High-Frequency Charge–Discharge Circuits – Suited for circuits requiring robust performance under fast charge/discharge loading and frequent switching.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 12.5 A (120 Hz) and 17.5 A (100 kHz) enable reliable performance under high-frequency, high-current conditions.
• Long rated life at operating temperature: 5000 hours at 85 °C under ripple load provides predictable end-of-life behavior for design planning.
• Secure screw-terminal connections: Robust mechanical and electrical attachment for industrial assemblies and serviceability.
• Wide operating temperature range: –40 °C to +85 °C accommodates a broad set of industrial environments.
• Clear electrical limits: Specified leakage current and insulation resistance values allow engineers to design to measurable performance criteria.
• RoHS compliance: Meets current RoHS directive requirements for restricted substances.
