LNT2D333MSEB

The LNT2D333MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering 33,000 µF of capacitance at a 200 V rating. Designed for general-purpose power applications, it provides large bulk energy storage and high ripple-current handling in a robust radial can with screw terminals.

This part is specified for operation from −25°C to 105°C with a rated endurance of 2,000 hours at 105°C. Key electrical parameters include a capacitance tolerance of ±20%, tangent of loss angle (tanδ) of 0.25 (measured at 20°C, 120 Hz), and specified leakage current and ripple-current ratings for both low and high frequencies.

Key Features

• Bulk Capacitance & Voltage — 33,000 µF nominal capacitance at a 200 V rated voltage, with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Temperature Endurance — Rated for operation up to 105°C with an endurance rating of 2,000 hours at 105°C under rated ripple current conditions.
• Ripple Current Capability — Low-frequency ripple current of 16.6 A at 120 Hz and high-frequency ripple current of 19.92 A at 100 kHz, supporting demanding AC components of power systems.
• Loss and Leakage — Tangent of loss angle (tanδ) specified at 0.25 (20°C, 120 Hz). Leakage current specified at 5,000 µA.
• Robust Mechanical and Mounting Options — Radial can with screw terminals for secure connections and easy mounting in systems requiring high-capacitance bulk components (physical size: φ90 × 220 mm).
• Compliance & Packaging — RoHS-compliant construction; supplied in cardboard packing for bulk handling.

Typical Applications

• General-purpose power electronics — Bulk energy storage and smoothing where high capacitance and 200 V rating are required.
• Industrial power supplies — Handles substantial ripple currents and elevated ambient temperatures up to 105°C for sustained operation.
• DC link and filtering — Large capacitance and screw-terminal mounting simplify integration into DC-link or filtering stages in power conversion equipment.

Unique Advantages

• Large-capacitance solution: 33,000 µF provides significant bulk energy storage to stabilize DC rails and reduce voltage ripple.
• High ripple handling: Specified ripple currents (16.6 A at 120 Hz, 19.92 A at 100 kHz) support demanding AC-loading conditions in power circuits.
• Elevated temperature rating: Rated to 105°C with a 2,000-hour endurance at that temperature, enabling reliable use in warmer environments.
• Screw-terminal convenience: Robust screw terminals simplify secure, low-impedance connections in high-current assemblies.
• Measurable loss performance: tanδ defined at 0.25 (20°C, 120 Hz) for predictable dissipation characteristics during design and validation.
• RoHS compliance and packaging: Environmentally compliant construction and cardboard packing for standard handling and storage.
