LNC2V122MSEFBN

The LNC2V122MSEFBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power electronics. It delivers 1.2 mF capacitance at a 350 V rating with polarization and is optimized for applications that require high ripple-current handling and compact packaging.

Targeted use cases include inverter circuitry, industrial power supplies and high-frequency regenerative voltage systems for AC servomotors and general inverters. The part is designed for sustained operation at elevated temperatures, with a specified load life under ripple current at 85°C.

Key Features

• Capacitance & Voltage — Rated capacitance 1.2 mF (1200 µF) with a 350 V DC rating and capacitance tolerance ±20% (at 120 Hz, 20°C).
• Mounting & Package — Screw terminal mounting in a radial can package (can with screw terminals) for secure mechanical and electrical connections; physical dimensions L: 6 × D: 5.1 cm and Height (seated) max 2.362 inch.
• Temperature Range & Lifetime — Operating temperature range –40°C to +85°C with load-life specification of 5000 hours at 85°C when ripple current is applied.
• High Ripple-Current Capability — Rated ripple current 8.6 A at 120 Hz and 12.04 A at 100 kHz, enabling use with high-frequency charge/discharge and regenerative loads.
• Endurance & Charge-Discharge Robustness — Endurance requirements: capacitance, tan δ and leakage current limits met after DC bias plus rated ripple current for 5000 hours at 85°C; specified charge-discharge endurance of 50 million cycles (ΔV = rated voltage × 0.3, 3 Hz).
• Leakage & Insulation — Leakage current after 5 minutes at 20°C is specified as not more than 3√V (µA) or 5 mA, whichever is smaller. Insulation resistance is greater than 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Proof — No abnormality during AC 2500 V, 1 minute application between terminal and bracket.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Smoothing and energy-buffering in inverter circuitry for motor drives and industrial power conversion.
• AC Servomotor Regeneration — Handling high-frequency regenerative voltages and fast charge/discharge cycles in servo drive systems.
• Industrial Power Supplies — Bulk energy storage and ripple suppression in industrial power-supply designs subject to sustained ripple loading at elevated temperatures.
• High-Frequency Regenerative Systems — Use where high ripple current at kHz-range switching is required, leveraging the 100 kHz ripple rating.

Unique Advantages

• High ripple-current handling: 8.6 A at 120 Hz and 12.04 A at 100 kHz support demanding switching and regenerative loads.
• Smaller size with higher performance: Designed to be smaller-sized while offering higher ripple current than comparable LNC-series predecessors LNX and LNK, enabling tighter packaging in power racks and cabinets.
• Long elevated-temperature life: Load-life rating of 5000 hours at 85°C under ripple current provides predictable long-term performance in hot operating environments.
• Robust charge-discharge endurance: Qualified for 50 million charge-discharge cycles (ΔV = 0.3×rated voltage), supporting high-speed switching applications.
• Screw-terminal reliability: Screw-terminal radial can package provides secure electrical connections suitable for industrial assemblies and repeated servicing.
• Documented electrical safeguards: Specified leakage current limits, insulation resistance >100 MΩ at DC 500 V, and AC 2500 V voltage-proof test criteria increase design confidence.
