LNT2V331MSEC

The LNT2V331MSEC is a Nichicon LNT series aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose high-voltage power applications. It provides 330 µF capacitance at a 350 V rating with screw terminals for robust electrical and mechanical connections.

Engineered for sustained operation at elevated temperatures, this part offers a 5000-hour endurance at 105°C, high ripple-current capability across low and high frequencies, and RoHS compliance—features that support power smoothing, energy storage and decoupling in industrial and power-electronics systems.

Key Features

• Core electrical — 330 µF capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20°C) and rated voltage of 350 V.
• Power-handling and ripple capability — Low-frequency ripple current of 2.10 A at 120 Hz and high-frequency ripple current of 2.94 A at 100 kHz for effective ripple suppression in power rails.
• Endurance and temperature — Rated for 5,000 hours of operation at 105°C under rated ripple conditions; operating temperature range −25°C to +105°C.
• Leakage and dissipation — Specified leakage current of 1,010 µA and tangent of loss angle (tanδ) of 0.2 (measured at 20°C, 120 Hz) for predictable electrical performance.
• Mechanical and mounting — Screw terminal, radial can package (φ35 × 80 mm) for secure clamp or bus-bar connections and straightforward installation or replacement.
• Compliance and supply — RoHS compliant; supplied in cardboard packing and listed as mass production status.

Typical Applications

• Power supply smoothing — Bulk filtering and energy storage on high-voltage DC rails where 350 V rating and 330 µF capacitance reduce ripple and stabilize supply voltage.
• Power conversion / DC link — DC-link and intermediate-stage decoupling in converters and inverters that require high-voltage capacitance and sustained ripple handling.
• Industrial equipment — Energy buffering and transient suppression in industrial control systems and power electronics operating up to 105°C.

Unique Advantages

• High-voltage capability: 350 V rating enables use on elevated DC rails without series stacking.
• Robust ripple performance: Specified ripple currents at both 120 Hz and 100 kHz support a range of switching- and line-frequency applications.
• Extended thermal endurance: 5,000-hour life at 105°C provides predictable long-term performance in high-temperature environments.
• Screw-terminal reliability: Screw terminals deliver durable, low-resistance connections for heavy-current paths and easier maintenance.
• Predictable leakage and loss: Clear leakage current and tanδ specifications aid in system-level power-loss and thermal budgeting.
• RoHS compliant and production ready: Environmentally compliant and available in mass-production packaging for volume designs.
