LNC2V122MSEF

The LNC2V122MSEF is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNC series, designed for industrial power electronics. It delivers 1.2 mF nominal capacitance at a 350 V rating in a compact radial can with screw terminals for robust high‑current connections.

Engineered for inverter and regenerative applications, this part offers a high ripple‑current capability and a 5000‑hour load life at 85°C, making it suited for industrial power supplies, AC servomotor regenerative circuits and general inverter topologies.

Key Features

• Capacitance & Tolerance — 1.2 mF nominal (1200 µF) with ±20% tolerance at 120 Hz, 20°C.
• Voltage Rating — Rated for 350 V DC operation.
• High Ripple Current — Rated ripple current of 8.6 A at 120 Hz and 12.04 A at 100 kHz for demanding switching and regenerative loads.
• Load Life — Rated for 5000 hours when subjected to rated DC bias plus rated ripple current at 85°C.
• Temperature Range — Operational from −40°C to +85°C.
• Mounting & Package — Screw terminal mounting in a radial can package for secure, low‑impedance connections.
• Leakage & Insulation — Series specification: after 5 minutes at rated voltage leakage current ≤ 3√V (µA) or 5 mA (whichever is smaller); insulation resistance ≥ 100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Compact footprint: length 6.0 cm × diameter 5.1 cm; designed to be smaller than comparable LNX/LNK series parts while supporting higher ripple currents.

Typical Applications

• Industrial inverter power supplies — Bulk and smoothing capacitance for inverter DC‑link stages where high ripple tolerance and long life at elevated temperature are required.
• AC servomotor regenerative circuits — Suitable for handling high‑frequency regenerative voltages and fast charge/discharge cycles in servo drives.
• General inverter and motor drive systems — Supports pulse‑loaded environments and high‑speed charge/discharge behavior over extended operational life.

Unique Advantages

• Higher ripple current capability — Supports 8.6 A (120 Hz) and 12.04 A (100 kHz) to handle heavy switching and regenerative currents without compromising performance.
• Compact, screw‑terminal package — Radial can with screw terminals enables reliable, low‑impedance connections in space‑constrained power assemblies.
• Long rated load life — 5000 hours at 85°C under rated ripple conditions provides predictable end‑use longevity for industrial applications.
• Wide operating temperature range — −40°C to +85°C operation covers common industrial ambient conditions.
• Measurable leakage and insulation criteria — Defined leakage current limits and insulation resistance specifications facilitate design validation and safety checks.
• RoHS compliant — Conforms to relevant RoHS directives for regulatory alignment in commercial products.
