LNT1C683MSEN

The LNT1C683MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, delivering 68,000 µF nominal capacitance at a 16 V rated voltage. Engineered for general-purpose power applications, it combines very high bulk capacitance with robust ripple-current capability and a 105°C operating range for demanding thermal environments.

This radial, can-style capacitor with screw terminals is offered in mass production packaging (cardboard) and is suitable where large capacitance, secure high-current connections, and long-term endurance at elevated temperatures are required.

Key Features

• High Capacitance: 68,000 µF (68 mF) nominal capacitance for bulk energy storage and smoothing.
• Rated Voltage: 16 V rated voltage suitable for low-voltage DC systems.
• Ripple Current Capability: Low-frequency ripple current 7.1 A (120 Hz) and high-frequency ripple current 8.165 A (100 kHz) to support heavy ripple loading.
• Temperature and Endurance: Operating temperature range –40°C to +105°C with rated lifetime of 2,000 hours at 105°C under rated ripple conditions.
• Electrical Quality: Capacitance tolerance ±20% and tangent of loss angle (tan δ) 0.6 measured at 20°C, 120 Hz for predictable AC performance.
• Leakage Current: Specified leakage current 3,120 µA after initial application of rated voltage.
• Robust Mechanical Package: Radial can with screw terminals (φ51 × 80 mm), secure M5 terminal hardware and cardboard packing for handling and assembly.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• Power Supply Bulk Filtering: Large capacitance and high ripple current capability provide effective smoothing and hold-up in general-purpose DC power supplies.
• Industrial Power Electronics: Screw-terminal construction and robust ripple handling make this part well suited for industrial control equipment and power modules requiring secure high-current connections.
• Energy Storage for DC Systems: High capacitance supports short-term energy buffering and transient suppression in low-voltage DC distribution and backup systems.
• General-Purpose Electronic Equipment: Designed for applications that require substantial bulk capacitance, elevated temperature endurance, and reliable long-term performance.

Unique Advantages

• Substantial Bulk Storage: 68,000 µF nominal capacitance reduces the number of components needed for large energy-storage requirements.
• High Ripple Handling: Rated for 7.1 A (120 Hz) and 8.165 A (100 kHz) ripple current, enabling sustained operation under heavy AC loading.
• High-Temperature Endurance: Rated to +105°C with a 2,000-hour life at 105°C, supporting designs that operate at elevated ambient temperatures.
• Secure, Serviceable Connections: Screw-terminal terminations (M5 nominal bolt for φ51 size) allow robust, low-resistance connections and straightforward mechanical mounting.
• Design Predictability: Specified tan δ, leakage current, and ±20% tolerance provide clear electrical parameters for system-level design and simulation.
• RoHS Compliant & Production Ready: RoHS status and mass-production availability support regulatory compliance and procurement planning.
