LNT1E333MSEN

The LNT1E333MSEN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNT series, offering 33,000 µF capacitance at a 25 V rating with polar construction. It is designed for general‑purpose power electronics where large bulk capacitance, high ripple current capability, and robust thermal endurance are required.

Key attributes include a wide operating temperature range of −40°C to +105°C, 2,000 hours of rated life at 105°C, and RoHS compliance, making it suitable for demanding industrial and equipment-level power applications.

Key Features

• High Capacitance: 33,000 µF provides substantial bulk energy storage for smoothing and buffering in power rails and energy reservoir applications.
• 25 V Rated Voltage: Rated for 25 V operation with ±20% capacitance tolerance at 120 Hz and 20°C, enabling predictable performance in mid‑voltage systems.
• Screw Terminal Package: Radial can with screw terminals simplifies secure, low‑impedance connections for high‑current installations.
• High Ripple Current Capability: 6.2 A at 120 Hz (low frequency) and 7.13 A at 100 kHz (high frequency) support heavy AC ripple and high switching frequency environments.
• Electrical Loss Characteristic: tan δ (DF) of 0.4 maximum at 20°C and 120 Hz, allowing designers to account for dissipation in thermal and reliability calculations.
• Leakage and Endurance: Specified leakage current of 2,720 µA and rated life of 2,000 hours at 105°C under applied ripple, with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Robust Temperature Range: Operates from −40°C to +105°C to accommodate a variety of ambient and elevated temperature environments.
• Regulatory Compliance: RoHS compliant to applicable directives.

Typical Applications

• Power Supplies: Bulk smoothing and ripple filtering for general‑purpose power supplies, leveraging 33,000 µF capacitance and high ripple current ratings.
• DC Link / Energy Buffering: Energy storage and buffering in mid‑voltage DC link circuits where high capacitance and screw‑terminal mounting are beneficial.
• Industrial Power Electronics: Support for filtering and transient buffering in industrial equipment and power conversion systems operating within −40°C to +105°C.
• UPS and Backup Systems: Bulk capacitance for hold‑up and ride‑through functions in uninterruptible power supply and backup circuits.

Unique Advantages

• Large Stored Energy in a Compact Can: 33,000 µF at 25 V provides significant bulk capacitance while maintaining a φ35 × 100 mm package footprint.
• High Ripple Endurance: Rated ripple currents of 6.2 A (120 Hz) and 7.13 A (100 kHz) reduce stress on upstream components and improve performance in switching environments.
