LNT1J334MSEN

The LNT1J334MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series designed for general-purpose power applications. It provides very high capacitance (330,000 µF) at a rated voltage of 63 V in a radial can with screw terminals for secure, high-current connections.

Key design attributes include operation across −40°C to +105°C, a rated endurance of 2,000 hours at 105°C under rated ripple conditions, and RoHS compliance. The part is produced in a φ100 × 250L can (25 × 10 cm) and is available in mass-production quantities with cardboard packing.

Key Features

• Capacitance & Voltage — 330,000 µF nominal capacitance with a tolerance of −20% to +20% at 120 Hz, 20°C; rated for 63 V operation.
• Screw Terminal Mounting — Radial can package with screw terminals for robust mechanical and electrical connection suitable for high-current bus applications.
• High Ripple Current Handling — Rated ripple current of 26.1 A at 120 Hz and 30.02 A at 100 kHz, enabling sustained AC ripple performance under load.
• Endurance & Temperature Range — Specified for operation from −40°C to +105°C with a life/endurance rating of 2,000 hours at 105°C when operated under rated ripple conditions.
• Leakage and Dissipation — Leakage current specified at 5000 µA and a tangent of loss angle (tan δ) of 0.6 (measured at 20°C, 120 Hz), providing clear electrical behavior for design margin calculations.
• Physical Size & Packaging — Large-format capacitor in φ100 × 250L (25 × 10 cm) size; supplied in cardboard packing for bulk handling.
• Regulatory Status — RoHS compliant.

Typical Applications

• General-purpose power systems — Bulk capacitance for smoothing and energy buffering in industrial and electronic power assemblies where large charge storage is required.
• Power conditioning modules — Use in DC link or filter stages that require high ripple current capability and sustained operation at elevated temperatures.
• Industrial power electronics — Suitable where robust screw-terminal connections and high capacitance are needed for power conversion and conditioning circuits.

Unique Advantages

• Very high capacitance in a single device — 330,000 µF reduces the need for multiple smaller capacitors, simplifying PCB layout and BOM.
• High ripple current capability — Rated ripple currents of 26.1 A (120 Hz) and 30.02 A (100 kHz) support heavy AC loading and reduce thermal stress in systems.
• Robust screw-terminal connections — Mechanical reliability for high-current bus connections and easy integration with brackets or lugged wiring.
• Rated for elevated temperatures — Endurance specified at 105°C for 2,000 hours provides predictable aging and lifecycle planning in warm operating environments.
• Clear electrical characterization — Specified leakage current and tan δ (0.6 at 20°C, 120 Hz) make it straightforward to model and validate in power designs.
• Regulatory compliance — RoHS status supports deployment in regulated markets and production environments.
