LNT2G331MSEC

The LNT2G331MSEC is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides 330 µF capacitance at a 400 V rated voltage in a radial can with screw terminals for secure electrical and mechanical connections.

Built for demanding environments, this part combines high-voltage capability, measurable ripple handling (2.3 A at 120 Hz and 3.22 A at 100 kHz), and a 5,000-hour endurance rating at +105°C to support robust power filtering and energy-storage needs across a range of equipment.

Key Features

• Electrical Performance — 330 µF nominal capacitance with ±20% tolerance and a rated voltage of 400 V, suitable for high-voltage DC bus and bulk energy-storage roles.
• Ripple Current Capacity — 2.3 A at 120 Hz (low frequency) and 3.22 A at 100 kHz (high frequency), enabling reliable smoothing of both low- and high-frequency ripple components.
• Leakage and Losses — Specified leakage current of 1080 µA and a tan δ of 0.2, providing predictable electrical behavior for design verification.
• Endurance and Temperature — Rated for 5,000 hours of life at +105°C and an operating temperature range of −25°C to +105°C for prolonged service in thermally stressed systems.
• Mechanical and Mounting — Radial can with screw terminals and a φ35 × 80 mm package (L: 8 × D: 3.5 cm) for robust, low-impedance connections and secure mounting.
• Compliance and Packaging — RoHS compliant and supplied in cardboard packing; available in mass production quantities.

Typical Applications

• General-purpose power equipment — Bulk energy storage and DC bus smoothing where 400 V capability and substantial capacitance are required.
• Industrial power supplies — Filtering and ripple attenuation in high-voltage power converters and line-side circuits.
• Power conditioning systems — Supporting sustained ripple currents and thermal endurance in conditioned power applications.

Unique Advantages

• High-voltage capacity: 400 V rating lets designers use a single capacitor for higher-voltage DC buses, reducing component count.
• Broad ripple performance: Specified ripple ratings at both 120 Hz and 100 kHz support designs dealing with mixed-frequency noise and switching residues.
• Long high-temperature endurance: 5,000 hours at +105°C provides predictable life in thermally demanding installations.
• Screw-terminal reliability: Screw terminals provide secure, low-impedance connections suitable for repeated assembly and robust current paths.
• RoHS compliance and production readiness: Environmentally compliant construction and mass-production availability simplify procurement and design planning.
