LNT1E334MSE

The LNT1E334MSE is a large-can, screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series designed for general-purpose power applications. With a nominal capacitance of 330,000 µF and a rated voltage of 25 V, it delivers high bulk energy storage and strong ripple-handling capability in a rugged, screw-terminal package.

Engineered for elevated-temperature operation, this capacitor supports an operating range of −40 °C to +105 °C and an endurance rating of 2,000 hours at 105 °C, making it suitable for demanding power-conditioning roles in industrial and electronics equipment.

Key Features

• High Capacitance & Rated Voltage — 330,000 µF (330 mF) at 25 V provides substantial bulk energy storage for supply smoothing and hold-up.
• Robust Ripple Performance — Low-frequency ripple current of 20.8 A at 120 Hz and high-frequency ripple current of 23.92 A at 100 kHz support heavy AC ripple and switching noise rejection.
• Endurance at Elevated Temperature — Rated for 2,000 hours at 105 °C under rated ripple conditions, suitable for sustained high-temperature operation.
• Electrical Characteristics — Tangent of loss angle (tan δ) of 1.5 (measured at 20 °C, 120 Hz) and leakage current of 5,000 µA, enabling predictable performance in power circuits.
• Polarized, Screw-Terminal Mounting — Polarized design with screw terminals simplifies high-current connections and mechanical retention in large-can assemblies.
• Mechanical Size & Packaging — Compact large-can footprint (φ90 × 140L; L: 14 × D: 9 cm) delivered in cardboard packing for safe handling and storage.
• Regulatory Compliance — RoHS compliant, supporting regulatory requirements for lead-free assemblies.

Typical Applications

• Power supply bulk filtering — Use the 330,000 µF capacitance and 25 V rating to smooth DC rails and provide energy buffering for power supplies.
• DC link and energy storage — The high capacitance and high ripple-current capability make it suited for DC-link smoothing in converters and inverters.
• Industrial electronics — Designed for general-purpose industrial equipment that requires sustained operation at elevated temperatures (−40 °C to +105 °C).

Unique Advantages

• Large bulk capacitance: 330,000 µF offers substantial energy storage in a single component, reducing the need for multiple parallel parts.
• High ripple tolerance: Rated ripple currents of 20.8 A (120 Hz) and 23.92 A (100 kHz) enable reliable operation with heavy AC or switching transients.
• Heat-resilient endurance: Rated life of 2,000 hours at 105 °C under rated ripple conditions provides predictable long-term performance in hot environments.
• Screw-terminal connectivity: Screw terminals facilitate secure, low-impedance connections for high-current applications and simplified assembly.
• Compact large-can form factor: φ90 × 140L packaging balances capacity with a manageable footprint for system integration.
• RoHS compliance: Meets RoHS requirements for lead-free production and regulatory alignment.
