LNT1A683MSEN

The LNT1A683MSEN is a screw‑terminal aluminum electrolytic capacitor in Nichicon's LNT series, offering high bulk capacitance in a robust radial can with screw terminals. Designed for general‑purpose applications, it delivers large energy storage and reliable filtering in systems that require polarized, screw‑mounted capacitors.

This part combines 68 mF capacitance at a 10 V rating with high ripple current capability and a wide operating temperature range, making it suitable for equipment that demands sustained performance up to +105°C.

Key Features

• High Capacitance: 68 mF (68,000 µF) nominal capacitance for substantial bulk energy storage and smoothing.
• Voltage Rating: 10 V rated voltage suitable for low‑voltage power rails and storage applications.
• Ripple Current Performance: 6.8 A low‑frequency ripple current (120 Hz) and 7.82 A high‑frequency ripple current (100 kHz) to support heavy AC stress and decoupling duties.
• Loss Tangent (tan δ): tanδ (DF) = 0.8 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for thermal and stability planning.
• Leakage Current: Specified leakage current of 2,470 µA for bias and standby current budgeting.
• Thermal and Endurance Rating: Operational temperature range from −40°C to +105°C with a rated life of 2,000 hours at 105°C.
• Mounting and Package: Screw terminal, radial can design (φ51×80L) with M5 terminal pitch and screw terminals for secure, low‑resistance connections.
• Tolerance and Polarization: Capacitance tolerance −20% to +20%; polarized device for correct orientation in DC circuits.
• Regulatory: RoHS compliant.

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling on low‑voltage power rails where high capacitance and screw‑terminal mounting are required.
• Industrial power modules: Energy storage and ripple handling in equipment that operates across a wide temperature range up to +105°C.
• Power supply reservoirs: Local energy buffering for converters and regulators needing large capacitance and significant ripple current capacity.

Unique Advantages

• Large stored energy in a compact can: 68 mF nominal delivers substantial bulk capacitance for smoothing and hold‑up without complex parallel arrangements.
• Strong ripple handling: High ripple current ratings at both low and high frequencies reduce heating and extend usable life under AC stress.
• Designed for elevated temperatures: Rated for operation to +105°C with a specified 2,000‑hour life at that temperature, enabling reliable performance in hot environments.
• Secure screw‑terminal mounting: Radial can with screw terminals provides robust electrical and mechanical connection for high‑current applications.
• Predictable electrical characteristics: Specified tanδ and leakage current values support accurate thermal and leakage budgets in system design.
• RoHS compliant: Meets regulatory requirements for lead‑free assemblies.
