LNK2V682MSEG

The LNK2V682MSEG is a Nichicon LNK-series aluminum electrolytic capacitor in a screw-terminal radial can. It delivers 6.8 mF of capacitance at a 350 V rating and is intended for general-purpose power applications that require large capacitance and secure screw-terminal connections.

Designed for continuous use up to 85°C with a 5000-hour load-life rating, this part combines high capacitance, high-voltage capability, and robust terminal mounting for demanding power-electronics environments.

Key Features

• High Capacitance & Voltage — 6.8 mF (6800 µF) capacitance at a 350 V rated voltage for bulk energy storage and smoothing duties.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, low-resistance mechanical and electrical connections for power modules and assemblies.
• Endurance at Elevated Temperature — Rated life of 5000 hours at 85°C under specified ripple-current conditions, supporting long-term operation in heated enclosures.
• Ripple Current Performance — Specified ripple handling of 19.6 A at 120 Hz and 27.44 A at 10 kHz to support power-supply ripple and high-frequency decoupling needs.
• Electrical Characteristics — Polarized design, capacitance tolerance ±20%, tangent of loss angle (tanδ) = 0.2, and measured leakage current of 4.48 mA.
• Compact Screw-Can Package — Physical size φ63.5 × 155 mm (L: 15.5 × D: 6.35 cm) with radial screw-terminal can packaging for straightforward mechanical integration.
• Environmental Compliance — RoHS compliant, supporting regulatory requirements for restricted substances.

Typical Applications

• General-purpose power systems — Use where large bulk capacitance at high DC voltage is required to stabilize and filter supply rails.
• Power modules and assemblies — Screw-terminal mounting provides a secure connection for high-current power assemblies and bus capacitors.
• High-ripple environments — Suitable where elevated ripple currents occur, backed by specified ripple ratings at 120 Hz and 10 kHz.
• Industrial equipment — Designed for continuous operation up to 85°C with a 5000-hour rated life for extended service in industrial applications.

Unique Advantages

• Large stored energy at high voltage — 6800 µF at 350 V provides substantial bulk capacitance for smoothing and hold-up functions.
• Secure mechanical and electrical connection — Screw-terminal radial can reduces the risk of terminal loosening and simplifies field wiring.
• Long-term reliability at elevated temperature — 5000-hour load-life rating at 85°C gives predictable endurance for thermal-stressed applications.
• High-frequency ripple capability — Ripple current specifications up to 10 kHz support both low- and high-frequency power-conditioning tasks.
• Measured electrical data — Specified tanδ and measured leakage current provide clear electrical acceptance criteria for design and validation.
• Regulatory alignment — RoHS compliance helps meet environmental substance restrictions for electronic products.
