LNU2H272MSEG

The LNU2H272MSEG is a high-voltage aluminum electrolytic capacitor in a screw-terminal can designed for industrial power applications. It provides 2700 µF capacitance at a 500 V rating with a robust screw-terminal package suited to high-current, high-frequency power environments.

Targeted at inverter circuitry, motor-drive and regenerative systems, this capacitor combines high ripple-current capability, long endurance at elevated temperature, and a compact high-voltage form factor for space-constrained power designs.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 500 V with ±20% tolerance (120 Hz, 20°C), suitable for high-voltage DC bus applications.
• High Ripple Current Performance — Rated ripple current of 9.6 A at 120 Hz and 13.44 A at 10 kHz to handle both low-frequency and high-frequency AC components in power converters.
• Endurance at Elevated Temperature — 5000 hours life rating at 105°C under rated ripple conditions, designed for sustained operation in hot industrial environments.
• Wide Operating Range — Operating temperature from −40°C to +105°C for reliable performance across typical industrial temperature extremes.
• Electrical Characteristics — Specified tan δ (DF) of 0.2 and leakage current of 3480 µA, with polarized construction for DC bus and energy storage roles.
• Robust Screw-Terminal Package — Radial can with screw terminals and M5 stud compatibility for secure, high-current connections in power assemblies.
• Compact High-Voltage Form Factor — φ63.5 × 135 mm footprint (diameter × length) provides a smaller high-voltage solution within the LNU series.
• RoHS Compliant — Meets RoHS directive requirements for use in regulated global applications.

Typical Applications

• Industrial Power Supplies — Bulk and smoothing capacitor for inverter-fed power supplies where high voltage and sustained ripple handling are required.
• Inverters and Motor Drives — DC bus support and energy buffering in inverter circuitry and AC servomotor drives.
• Regenerative Systems — Handles high-frequency regenerative voltage and charge-discharge stress encountered in braking and energy-recovery systems.
• High-Speed Charge–Discharge Circuits — Designed to cope with repetitive high-speed charge and discharge loading in power conversion topologies.

Unique Advantages

• High-voltage capability in a compact can: 500 V rating with a φ63.5 × 135 mm envelope enables high-voltage DC bus designs without an oversized footprint.
• Dual-frequency ripple handling: Substantial ripple ratings at both 120 Hz and 10 kHz reduce thermal stress and extend service life under mixed-frequency loading.
• Long life at elevated temperature: 5000 hours at 105°C under rated ripple current supports continuous operation in demanding industrial environments.
• Screw-terminal robustness: M5-compatible screw terminals provide secure, low-resistance connections for high-current power assemblies.
• Wide ambient range: −40°C to +105°C operating range maintains electrical stability across common industrial temperature extremes.
• Regulatory compliance: RoHS-compliant construction supports use in markets with restricted substances requirements.
