LNT1K682MSE

The LNT1K682MSE is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNT series, specified for general‑purpose power applications. It delivers 6.8 mF (6800 µF) capacitance at an 80 V rated voltage in a radial can with screw terminals, providing high bulk energy storage and robust mounting for industrial and commercial equipment.

Key attributes include a wide operating temperature range of −40°C to +105°C, a rated lifetime of 2000 hours at 105°C, low‑frequency and high‑frequency ripple current capability, and RoHS compliance—making it suited to designs that require durable bulk capacitance and reliable ripple handling.

Key Features

• Electrical Performance — 6.8 mF capacitance with ±20% tolerance and an 80 V rated voltage for bulk energy storage and smoothing.
• Ripple Current Capability — 3.9 A low‑frequency ripple current (120 Hz) and 4.485 A high‑frequency ripple current (100 kHz), enabling effective ripple handling across a range of switching and line frequencies.
• Loss and Leakage — Maximum tanδ specified at 0.20 and measured leakage current of 2210 µA, providing predictable dissipation and leakage characteristics for system budgeting.
• Thermal and Lifetime — Rated for −40°C to +105°C operation with a specified life of 2000 hours at 105°C under rated ripple and DC bias conditions.
• Mechanical & Mounting — φ35 × 100 mm radial can with screw terminals for secure, serviceable electrical connections and robust chassis mounting.
• Packaging & Production — Cardboard packing and listed as mass production, suitable for volume deployment and standard inventory handling.
• Regulatory — RoHS compliant.

Typical Applications

• Power supplies — Bulk smoothing and energy buffering in general‑purpose power supplies, taking advantage of 6.8 mF capacitance and 80 V rating to reduce output ripple.
• DC link and power conversion — Use as a DC link or bulk capacitor in converters and inverters where the specified ripple current capability supports both low‑ and high‑frequency switching environments.
• Industrial equipment — Energy storage and decoupling in general‑purpose industrial electronics that operate across −40°C to +105°C and require a robust screw‑terminal connection.

Unique Advantages

• High bulk capacitance in a compact package: 6.8 mF in a φ35 × 100 mm radial can provides substantial energy storage for space‑sensitive designs.
• Screw‑terminal reliability: Screw terminals enable durable, low‑resistance connections and simplify installation or field service.
• Dual‑frequency ripple handling: Specified ripple current at both 120 Hz and 100 kHz supports designs using line frequency smoothing and high‑speed switching alike.
• Wide operating temperature and rated life: −40°C to +105°C operation with a 2000‑hour life at 105°C provides predictable endurance under elevated temperature and ripple stress.
• Defined electrical loss and leakage: tanδ of 0.20 and measured leakage allow precise thermal and leakage current budgeting in system design.
• Manufacturing readiness: Cardboard packing and mass production status make the part suitable for volume procurement and deployment.
