LNT2W332MSEG

The LNT2W332MSEG is a screw-terminal aluminum electrolytic capacitor designed for high-voltage, general-purpose power applications. It combines a 450V rated voltage with 3300µF capacitance in a robust radial can with screw terminals for secure electrical and mechanical connection.

Engineered for systems requiring bulk energy storage and high ripple handling, this capacitor delivers specified low- and high-frequency ripple currents, a broad operating temperature range, and a 5,000-hour life at 105°C for reliable operation in demanding environments.

Key Features

• Electrical rating — Rated capacitance of 3.3 mF (3300µF) with ±20% tolerance at 120Hz, 20°C, and a rated voltage of 450V, providing substantial bulk storage for high-voltage systems.
• High ripple-current capability — Handles 16.5 A at 120Hz (low frequency) and 23.1 A at 100kHz (high frequency), supporting heavy ripple loading from switching converters and power electronics.
• Loss and leakage — Specified tangent of loss angle (tan δ) of 0.2 and leakage current of 3650µA, enabling predictable dissipation and leakage behavior in design calculations.
• Thermal and lifetime performance — Rated for operation from –25°C to +105°C with a rated load life of 5,000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Robust mechanical design — Radial can package with screw terminals (φ63.5 × 150L size; nominal dimensions L: 15 cm × D: 6.35 cm) for secure mounting and reliable electrical connection; terminal hardware compatible with M5 bolt sizing for this diameter.
• Production and packaging — Cardboard packed and indicated as mass production status, suitable for volume deployment.
• Compliance — RoHS compliant per provided product information.

Typical Applications

• High-voltage power supplies — Bulk energy storage and smoothing at up to 450V; capacitance and ripple ratings help stabilize DC rails in power conversion systems.
• DC link and inverter stages — Large capacitance and high ripple-current capability support DC-link buffering and energy transfer in inverter and motor-drive circuits.
• Industrial power electronics — Designed for general-purpose industrial use where extended temperature range and a 5,000-hour life at 105°C are required.

Unique Advantages

• High-voltage bulk storage: 450V rating combined with 3300µF capacitance provides substantial energy density for high-voltage designs.
• Dual-frequency ripple handling: Rated ripple currents at both 120Hz and 100kHz let designers quantify performance across low- and high-frequency loading conditions.
• Predictable electrical behavior: Specified tan δ and leakage current values deliver measurable loss and leakage parameters for thermal and power-loss budgeting.
• Extended high-temperature life: 5,000-hour endurance at 105°C supports longer service intervals in elevated-temperature installations.
• Secure screw-terminal mounting: Radial can with screw terminals and appropriate bolt sizing (M5 for φ63.5) simplifies robust electrical connections in panel- and chassis-mounted applications.
• Volume-ready packaging: Cardboard packing and mass-production status ease procurement and assembly planning for larger projects.
