LNT1K683MSEB

The LNT1K683MSEB from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series, providing high bulk capacitance in a robust radial can package. With a rated voltage of 80 V and 68,000 µF (68 mF) capacitance, it is intended for general-purpose applications that require large energy storage and sustained ripple handling.

Key value comes from its high ripple-current capability (17 A at 120 Hz, 19.55 A at 100 kHz), wide operating temperature range (−40°C to +105°C) and a proven endurance rating of 2000 hours at 105°C, making it suitable for demanding power-system environments where long-term thermal stability and reliable electrical performance matter.

Key Features

• High Capacitance & Voltage: 68,000 µF at 80 V provides substantial bulk energy storage for smoothing and buffering in general-purpose power circuits.
• Robust Ripple Current Handling: Low-frequency ripple current 17 A (120 Hz) and high-frequency ripple current 19.55 A (100 kHz) for sustained operation under AC/rectified loads.
• High-Temperature Endurance: Rated for operation from −40°C to +105°C with a specified life of 2000 hours at 105°C under rated ripple and DC bias.
• Secure Screw-Terminal Mounting: Radial can with screw terminals for reliable, low-resistance connections; dimensions φ90 × 140L (L: 14 cm × D: 9 cm) and terminal hardware consistent with φ90 screw-terminal design.
• Electrical Characteristics: Capacitance tolerance −20% to +20% and leakage current specified at 5000 µA provide clear electrical expectations for design and qualification.
• Regulatory Compliance: RoHS compliant as indicated in the product data.

Typical Applications

• General-purpose power filtering: Large bulk capacitance and high ripple capability support smoothing and energy buffering in general-purpose power circuits.
• High-energy storage needs: The 68,000 µF capacity at 80 V is suitable where significant stored charge is required for short-term energy delivery or load transients.
• High-temperature environments: Designed for systems operating up to +105°C with a 2000-hour endurance specification at that temperature.

Unique Advantages

• Substantial energy density: 68 mF at 80 V delivers large stored energy in a single component, reducing part count for bulk storage needs.
• Dual-frequency ripple endurance: Rated ripple current values at both 120 Hz and 100 kHz let designers assess performance across low- and high-frequency stress conditions.
• Thermal reliability: Specified life of 2000 hours at 105°C ties performance expectations to elevated operating temperatures for longevity planning.
• Secure mechanical connection: Screw-terminal construction provides durable, low-impedance connections appropriate for repeated servicing or high-current applications.
• Clear electrical spec limits: Defined leakage current (5000 µA) and capacitance tolerance (−20% to +20%) enable predictable system behavior and easier specification matching.
• RoHS-compliant manufacturing: Conforms to RoHS requirements as stated in the product data.
