LNC2H122MTEG

The LNC2H122MTEG is a Nichicon LNC series aluminum electrolytic capacitor in a screw-terminal, stud-bolt mount configuration. It provides 1.2 mF (1200 µF) capacitance at a 500 V rating, designed for power electronics applications that require compact, high-ripple-capacity bulk energy storage.

Targeted for industrial power supplies and inverter circuitry, this capacitor is optimized for high-frequency regenerative voltage and high‑speed charge/discharge loading, offering a combination of elevated ripple-current capability and a long rated life at elevated temperature.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance.
• High Ripple-Current Performance: Low-frequency ripple current of 10.4 A (120 Hz) and high-frequency ripple current of 14.56 A (100 kHz), supporting demanding power cycling and filtering tasks.
• Loss Characteristics: Tangent of loss angle (tan δ) of 0.2 measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Robust Endurance: Rated life of 5000 hours at 85°C under specified ripple conditions, with series-level endurance and charge/discharge qualification for heavy-duty applications.
• Mounting & Package: Stud bolt (screw terminal) mount in a radial can package, form factor φ63.5 × 70 mm (L: 7 × D: 6.35 cm) for secure mechanical attachment and high-current connections.
• Operating Range & Compliance: Operational temperature range −40°C to +85°C and RoHS-compliant construction.
• Leakage & Reliability: Specified leakage current of 2320 µA and insulation/voltage-proof characteristics per the series datasheet for reliable long-term operation.

Typical Applications

• Industrial Inverters: Bulk energy storage and filtering for inverter circuitry in industrial power supplies where high ripple-current handling is required.
• AC Servomotor Regeneration: Handling high-frequency regenerative voltage in AC servomotor drives and regenerative braking circuits.
• High-Speed Charge/Discharge Power Circuits: Circuits that undergo rapid charge/discharge cycles benefit from the LNC series’ endurance for repeated cycling.
• General Power Electronics: Use as a DC-link or smoothing capacitor in power conversion systems that demand compact size with elevated ripple capability.

Unique Advantages

• High ripple-current capability: Provides 10.4 A at 120 Hz and 14.56 A at 100 kHz to support demanding filtering and regenerative loads without oversizing.
• Compact stud-mount form: Stud bolt screw terminals in a radial can reduce assembly complexity for secure high-current connections and mechanical stability.
• Long rated life at elevated temperature: 5000 hours at 85°C under rated ripple conditions helps ensure predictable service life in harsh industrial environments.
• Wide operating temperature: −40°C to +85°C suitability for a broad range of industrial operating conditions.
• Designed for high-speed cycling: Series-level validation covers extensive charge/discharge endurance, addressing applications with frequent voltage swings.
• RoHS compliant: Meets environmental compliance requirements for modern electronic systems.
