LNC2G472MSEGBN

The LNC2G472MSEGBN is a screw-terminal aluminum electrolytic capacitor delivering 4.7 mF (4700 µF) at 400 V in a compact radial can package. It is designed for industrial power electronics where high ripple handling and compact size matter, including inverter circuitry and high-frequency regenerative circuits for AC servomotors.

Key value propositions include high ripple-current capability across low and high frequencies, a rated operating range of −40 °C to +85 °C, and a demonstrated load life of 5000 hours at 85 °C under rated ripple conditions.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 400 V, with capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• High Ripple Current — Rated ripple current of 18.8 A at 120 Hz and 26.32 A at 100 kHz, enabling support for heavy AC ripple and high-speed charge–discharge cycles.
• Thermal & Life Performance — Operating temperature range −40 °C to +85 °C with a load life specified at 5000 hours at 85 °C when subjected to rated ripple current under DC bias.
• Durability & Endurance — Meets series endurance criteria: after endurance testing (DC bias plus rated ripple for 5000 hours at 85 °C) capacitance change remains within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√V μA or 5 mA, whichever is smaller (measurement at 20 °C).
• Package & Mounting — Radial can with screw terminals for robust mechanical and electrical connections in high-current industrial assemblies; package dimensions: L: 12 × D: 6.35 cm.
• Regulatory Compliance — Compliant with the RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in inverter-driven power supplies where high ripple currents and long life are required.
• Inverter Circuitry — DC-link and filter applications in inverter stages that demand high-frequency ripple tolerance and rapid charge–discharge capability.
• Regenerative Servo Drives — High-frequency regenerative voltage handling for AC servomotors and general inverter systems to support energy recovery and transient handling.
• High-Frequency Power Electronics — Applications requiring compact, high-current capacitors for switching supplies and charge–discharge cycling at kHz frequencies.

Unique Advantages

• High ripple-current capability: Explicit ripple ratings at 120 Hz and 100 kHz provide designers with verified values for thermal and lifetime budgeting.
• Compact radial screw-terminal package: Smaller size than comparable series while retaining screw-terminal robustness for secure connections in industrial assemblies.
• Proven endurance at elevated temperature: Specified 5000-hour load life at 85 °C under rated ripple current supports reliable long-term operation in hot environments.
• Wide operating temperature range: −40 °C to +85 °C allows deployment across a broad set of industrial ambient conditions.
• Clear leakage and insulation specifications: Defined leakage-current limits and insulation resistance/voltage-proof criteria support predictable behavior during design validation.
• RoHS compliant: Meets EU RoHS requirements for material content, easing regulatory conformity in product builds.
