LNC2G103MTEH

The LNC2G103MTEH is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series, configured for stud bolt mounting. It delivers 10,000 µF capacitance at a 400 V rating with polarized can-style screw terminals, optimized for high ripple-current and charge–discharge loading in power electronics.

Designed for industrial power supplies and inverter circuitry, this part targets applications requiring sustained ripple handling and long life under elevated temperatures, with a rated endurance of 5000 hours at 85°C and RoHS compliance.

Key Features

• Core electricals — 10,000 µF, 400 V: Rated capacitance 10,000 µF (10 mF) with a voltage rating of 400 V and capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• High ripple-current capability: Low-frequency ripple current of 29.5 A at 120 Hz and high-frequency ripple current of 41.3 A at 100 kHz, supporting heavy AC loading and fast charge–discharge cycles.
• Low-loss characteristic: Tangent of loss angle (tan δ) specified at 0.2 (measured at 20°C, 120 Hz), indicating controlled dissipation under typical measurement conditions.
• Long endurance at elevated temperature: Load life rated for 5000 hours at 85°C when subjected to DC bias plus rated ripple current (endurance criteria defined in the series datasheet).
• Robust leakage specification: Leakage current listed as 5000 µA (5 mA) for this part; series guidance also provides leakage limits based on capacitance and voltage conditions.
• Mechanical & mounting — stud bolt mount: Radial can with screw terminals for secure stud/bolt mounting; nominal dimensions φ76.2 × 165 mm (L: 16.5 × D: 7.62 cm) for panel or bracket installation.
• Wide operating range: Rated for operation from −40°C to +85°C, suitable for industrial temperature environments.
• Regulatory status: RoHS compliant per the product information.

Typical Applications

• Industrial Inverter Power Supplies: Used in inverter front-end and DC-link circuits where sustained ripple current and long life at 85°C are required.
• AC Servomotor Regeneration Circuits: Suited for high-frequency regenerative voltage handling in AC servomotor drive systems and similar motor-control equipment.
• General Power Electronics: Employed in general-purpose inverter and power-conversion applications that demand heavy charge–discharge loading and reliable DC filtering.

Unique Advantages

• High ripple-handling capability: Specified ripple currents of 29.5 A (120 Hz) and 41.3 A (100 kHz) enable the capacitor to handle substantial AC stress in power-electronic circuits.
• Designed for sustained high-temperature operation: 5000-hour endurance at 85°C provides predictable performance over long duty cycles under rated ripple and bias conditions.
• Smaller size with high performance: LNC series is specified as smaller-sized while maintaining high ripple current compared to related series, enabling tighter packaging in power racks or assemblies.
• Secure stud/bolt mounting: Screw-terminal stud mount and radial can package simplify mechanical retention and grounding in industrial enclosures.
• Measured dissipation control: Tan δ of 0.2 (20°C, 120 Hz) helps designers estimate losses and thermal behavior in application-specific thermal budgets.
• RoHS compliance: Meets RoHS directive requirements for materials compliance in commercial and industrial equipment.
