LNT1J683MSEN

The LNT1J683MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering very high capacitance (68,000 µF) in a radial can with screw terminals. It is designed for general‑purpose power applications that require bulk energy storage, high ripple current handling and robust thermal performance.

This part is rated 63 V with ±20% capacitance tolerance, a temperature range of −40°C to +105°C, and a specified endurance of 2,000 hours at 105°C, making it suitable where durable high‑capacitance electrolytic solutions are needed.

Key Features

• High Capacitance — 68,000 µF (68 mF) provides substantial bulk energy storage for power rails and filtering.
• Voltage Rating — 63 V rated voltage suitable for medium‑voltage power systems and DC bus applications.
• Polarized Screw‑Terminal Package — Radial can with screw terminals simplifies secure mechanical and electrical connections in chassis or bracketed assemblies.
• Robust Temperature Range — Operating range from −40°C to +105°C supports deployment in varied environmental conditions.
• Endurance — Rated life of 2,000 hours at 105°C under rated ripple current, aligned with LNT series load‑life specifications for this voltage range.
• High Ripple Current Capability — Low‑frequency ripple current of 13.5 A (120 Hz) and high‑frequency ripple current of 15.53 A (100 kHz) to support high‑stress power applications.
• Leakage and Dissipation — Specified leakage current of 5,000 µA and tanδ (DF) of 0.5 measured at 20°C, 120 Hz for predictable loss behavior.
• Physical Dimensions — Diameter φ76.2 mm × length 120 mm (L: 12 cm × D: 7.62 cm) with a seated height reference of 4.724 inches for mechanical planning.
• Compliance & Packaging — RoHS compliant; supplied in cardboard packing and available in mass production.

Typical Applications

• General‑purpose Power Filtering — Bulk smoothing and decoupling on DC rails where high capacitance and ripple handling are required.
• Energy Storage in Power Supplies — Use as a bulk reservoir for switch‑mode and linear power supplies to stabilize bus voltage under load transients.
• Industrial Power Electronics — Integration into cabinet or chassis assemblies that benefit from screw‑terminal mounting and high ripple capability.

Unique Advantages

• Large Stored Energy per Volume — 68,000 µF capacitance provides significant charge reservoir capacity for smoothing and hold‑up functions.
• High Ripple Current Rating — Rated ripple currents at both low and high frequencies reduce overheating risk under continuous ripple stress.
• Secure Mechanical Termination — Screw terminals enable reliable, low‑impedance connections and straightforward replacement or servicing.
• Thermal Endurance — Specified 2,000‑hour life at 105°C for sustained operation in elevated ambient temperatures within the rated conditions.
• Predictable Electrical Losses — Specified tanδ and leakage current figures support power‑loss budgeting and thermal design.
• Regulatory Compliance — RoHS compliance supports use in designs requiring restricted‑substance adherence.
