LNC2G472MSEG

The LNC2G472MSEG is a screw-terminal aluminum electrolytic capacitor designed for industrial power applications. It pairs a compact, radial can package with high ripple-current capability to support inverter circuitry, industrial power supplies and high-frequency regenerative voltage systems for AC servomotors and general inverters.

Key value propositions include high voltage handling (400 V), large capacitance (4700 μF), extended load life at elevated temperature, and RoHS compliance for regulated-system integration.

Key Features

• Capacitance & Voltage — 4700 μF rated capacitance at 400 V, polarized electrolytic construction suitable for bulk energy storage and smoothing in power converters.
• High Ripple Current — Rated ripple current of 18.8 A at 120 Hz and 26.32 A at 100 kHz, supporting high-frequency charge–discharge and heavy ripple loading in inverter and regenerative circuits.
• Temperature & Lifetime — Operating temperature range –40 °C to +85 °C with a load life of 5000 hours at 85 °C under rated ripple current conditions.
• Package & Termination — Screw terminal, radial can package for secure buss connections and easy serviceability in industrial systems. Physical dimensions: length 12 cm × diameter 6.35 cm; maximum seated height 4.724 inch.
• Reliability & Endurance — Endurance specifications include charge–discharge life test (50 million cycles at ΔV = rated × 0.3, 3 Hz) and defined insulation resistance and voltage-proof characteristics for robust operation.
• Electrical Characteristics — Capacitance tolerance ±20%; leakage current spec after 5 minutes is not more than 3√V μA or 5 mA (whichever is smaller); impedance stability at low temperature specified (Z(–40 °C)/Z(+20 °C) ≤ 8).
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing to support regulated DC rails and transient loads in industrial power systems.
• Inverter Circuits — DC link and smoothing capacitor for motor drives and power conversion stages that require high ripple tolerance and large capacitance.
• Regenerative Systems for AC Servomotors — Handles high-frequency regenerative voltages and fast charge–discharge cycles in servo and motion-control applications.
• General Inverters — Supports energy buffering and ripple absorption in general-purpose inverter designs used across factory automation and drive systems.

Unique Advantages

• High ripple-current capability: Explicitly rated at 18.8 A (120 Hz) and 26.32 A (100 kHz), enabling reliable operation under heavy AC ripple and fast switching conditions.
• Extended high-temperature life: 5000 hours at 85 °C under rated conditions provides predictable service life in elevated-temperature installations.
• Robust electrical safeguards: Defined leakage-current limits and insulation-resistance/voltage-proof test criteria support predictable behavior during system qualification.
• Screw-terminal convenience: Screw terminals and a radial can form factor simplify installation and allow secure, low-impedance connections for power systems.
• Designed for high-cycle regimes: Endurance testing includes 50 million charge–discharge cycles (ΔV = 0.3 × rated, 3 Hz), demonstrating suitability for repeat-charge regenerative scenarios.
• Regulatory compliance: RoHS conformity supports deployment in regulated environments without additional materials screening steps.

Why Choose LNC2G472MSEG?

LNC2G472MSEG is positioned for engineers specifying high-voltage bulk capacitance with high ripple tolerance in industrial power conversion and regenerative drive systems. Its combination of 4700 μF at 400 V, explicit ripple-current ratings at both low and high frequencies, and long load-life at 85 °C make it a practical choice where sustained energy buffering and frequent charge–discharge cycles are required.

This capacitor is suited to electrical designs that demand predictable endurance, clear electrical limits (leakage, impedance, insulation resistance), and the mechanical convenience of screw terminals. Its RoHS compliance and documented test criteria support long-term deployment and qualification within industrial product lifecycles.
