LNT1C684MSEB

The LNT1C684MSEB is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series, delivering very high capacitance (680000 µF) at a rated voltage of 16 V. It is a polarized, radial can package designed for applications that require large bulk energy storage and high ripple current handling in industrial and power electronics environments.

Engineered for sustained operation up to +105°C, this LNT series unit provides high low‑ and high‑frequency ripple capability along with robust endurance characteristics, making it suitable for power conversion, smoothing and DC link applications where high capacitance and reliable performance are required.

Key Features

• High Capacitance: 680000 µF (680 mF) provides substantial bulk energy storage for smoothing, buffering and DC link applications.
• Rated Voltage: 16 V rated voltage suitable for low‑voltage power rails and power conversion stages.
• Screw Terminal Mounting: Radial can with screw terminals enables secure, low‑impedance connections for high current systems and easy installation in rack or chassis assemblies.
• High Ripple Current Capacity: Low‑frequency ripple current 24 A (120 Hz) and high‑frequency ripple current 27.6 A (100 kHz) support heavy AC ripple and switching power converter loads.
• Operating Temperature and Endurance: Rated for −40°C to +105°C with an endurance of 2000 hours at +105°C, providing reliable behavior under elevated temperature operation.
• Electrical Characteristics: Capacitance tolerance −20% to +20% and tangent of loss angle (tan δ) = 2 (measured at 20°C, 120 Hz); leakage current specified at 5000 µA.
• Packaging and Production Status: Supplied in cardboard packing and listed as mass production.
• RoHS Compliant: Compliant with RoHS requirements as stated in product data.

Typical Applications

• Power conversion and DC link systems: Large capacitance and high ripple current ratings make the LNT1C684MSEB well suited for smoothing and energy storage on DC bus and inverter front‑ends.
• Industrial power supplies: Bulk storage for high‑current power supplies and converters where long ripple endurance and robust terminal connections are required.
• Uninterruptible power systems and backup supplies: Provides the bulk capacitance needed for short‑term energy buffering and ride‑through in UPS and standby systems.

Unique Advantages

• Exceptional bulk energy storage: 680000 µF nominal capacitance reduces the number of components needed for the same energy budget, simplifying BOM and board area allocation.
• High ripple acceptance across frequencies: Specified ripple currents at both 120 Hz and 100 kHz support designs using both line‑frequency and high‑frequency switching topologies.
• Robust screw‑terminal connectivity: Screw terminals provide mechanically secure, low‑impedance connections for heavy current paths and repeated servicing.
• Wide operating temperature range: −40°C to +105°C operation with a defined endurance at 105°C helps ensure predictable lifetime in elevated temperature environments.
• Production ready: Mass production status and cardboard packing support volume procurement and handling for manufacturing environments.
