LNK2V392MSEGBN

The LNK2V392MSEGBN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNK series designed for general-purpose power applications. It delivers 3.9 mF (3900 µF) capacitance with a 350 V rated voltage in a smaller-sized radial can with screw terminals.

Engineered for sustained operation, this polarized capacitor supports high ripple current and a 5000-hour load life at 85°C, making it suitable where sustained bulk capacitance, high ripple handling and secure screw-terminal connections are required.

Key Features

• Capacitance and Voltage — 3.9 mF (3900 µF) nominal capacitance with a 350 V rated voltage; capacitance tolerance ±20% (at 120 Hz, 20°C).
• High ripple current capability — Ripple current ratings of 12.8 A at 120 Hz and 17.92 A at 10 kHz provide robust AC ripple handling for demanding power conditions.
• Long load life — Rated for 5000 hours at 85°C under DC bias plus rated ripple current, with specified endurance characteristics after restoration to 20°C.
• Mechanical and mounting — Screw terminal, radial can package for secure bolted connections and easy assembly in power modules and panels.
• Operating range — Designed for operation from −25°C to +85°C to cover a broad range of general-purpose environments.
• Electrical integrity — Leakage current specified as not more than 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; AC 2500 V dielectric proof for 1 minute between terminal and bracket.
• Polarized design — Proper polarity marking and polarized construction suitable for DC bulk and filtering applications.
• RoHS compliant — Conforms to RoHS directive as noted in product documentation.
• Compact footprint — Smaller-sized LNK series form factor with physical dimensions L: 10 cm × D: 6.35 cm and a seated height up to 3.937 inch for space-constrained layouts.

Typical Applications

• Power conversion modules — Bulk smoothing and energy storage where high ripple current capability and long life at elevated temperatures are required.
• Industrial power equipment — General-purpose DC filtering and decoupling in industrial power supplies and control systems.
• Backup and hold-up circuits — Energy storage for sustaining DC rails during short interruptions, leveraging high capacitance and rated ripple handling.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings at both low and high frequency help manage AC stress in real-world power systems.
• Proven endurance: 5000 hours load life at 85°C under rated conditions supports longer maintenance intervals and predictable lifetime behavior.
• Secure screw-terminals: Bolt-style terminations provide reliable mechanical and electrical connections for high-current applications.
• Compact LNK series form: Smaller-sized radial can reduces board space while delivering high capacitance.
• Electrical safety margins: Defined leakage current limits, insulation resistance and AC voltage proof between terminal and bracket support robust system design.
• RoHS compliance: Meets environmental directive requirements for material content where applicable.
