LNC2G272MSEH

The LNC2G272MSEH is a screw-terminal aluminum electrolytic capacitor designed for industrial power applications. It delivers 2.7 mF capacitance at a 400 V rating in a radial can with screw terminals, optimized for inverter circuitry and high-frequency charge-discharge loading.

Built for rugged operation, this part is rated for operation from −40°C to +85°C, RoHS compliant, and specified for 5,000 hours of ripple-current endurance at 85°C, making it suited to demanding power-supply and regenerative-energy environments.

Key Features

• Capacitance & Voltage — 2.7 mF nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing bulk energy storage for power electronics.
• Screw Terminal Mounting — Radial can package with screw terminals for robust, low-resistance connections in power assemblies and easy field wiring.
• High Ripple-Current Capability — Rated ripple currents of 14.3 A at 120 Hz and 20.02 A at 100 kHz, supporting high-frequency inverter and regenerative loads.
• Thermal and Lifetime Ratings — Operating range −40°C to +85°C with a load-life specification of 5,000 hours at 85°C under ripple current application.
• Durable Charge–Discharge Endurance — Series-level endurance testing includes charge–discharge cycling (50 million cycles at ΔV = rated × 0.3, 3 Hz) with defined limits for capacitance, tan δ, and leakage current.
• Leakage and Insulation Characteristics — Leakage current and insulation resistance are specified in the datasheet (leakage current limit after 5 minutes; insulation resistance >100 MΩ at DC 500 V between terminal and bracket).
• Compact Footprint — Smaller-sized design within the LNC series while maintaining higher ripple capability; part dimensions: L: 6.5 × D: 7.62 cm with a seated height of 2.559 inches.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk energy smoothing and high-frequency regenerative voltage handling for AC servomotor drives and general inverter circuitry.
• Power Supplies — DC bus energy storage and ripple suppression in industrial power supplies where sustained ripple current and long life at elevated temperature are required.
• Regenerative Drive Systems — Supports high-speed charge–discharge cycles and high-frequency regenerative voltage conditions encountered in servo and motor drive systems.

Unique Advantages

• High Ripple Tolerance: Rated ripple currents up to 20.02 A at 100 kHz enable handling of high-frequency stress typical in modern inverter topologies.
• Proven Endurance: 5,000-hour load-life at 85°C and charge–discharge endurance testing provide measurable durability for continuous industrial operation.
• Robust Mechanical Connection: Screw-terminal radial can package simplifies assembly and ensures secure electrical and mechanical connections in power racks and panels.
• Compact, High-Performance Design: Smaller-sized LNC series form factor with high ripple capability allows designers to save space without sacrificing thermal or electrical performance.
• Clear Electrical Limits: Specified leakage, insulation resistance, and voltage-proof criteria permit predictable integration into safety- and performance-conscious designs.
