LNK2G392MSEGBN

The LNK2G392MSEGBN from Nichicon is a smaller-sized, screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides 3.9 mF (3900 µF) capacitance at a 400 V rating in a radial can with secure screw terminals.

Engineered for high ripple environments, this polarized capacitor combines high ripple-current capability with a durable load life of 5000 hours at 85°C and RoHS compliance, making it suitable where robust DC filtering and energy buffering are required within the stated operating conditions.

Key Features

• Capacitance and Voltage — 3.9 mF (3900 µF) nominal capacitance with a 400 V rated voltage; tolerance ±20% at 120 Hz, 20°C.
• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance connections and reliable mechanical mounting.
• High Ripple-Current Handling — Rated ripple current: 12.8 A at 120 Hz and 17.92 A at 10 kHz, supporting demanding ripple environments (use within rated conditions).
• Thermal and Lifetime Performance — Operating temperature range −25°C to +85°C with a load life of 5000 hours at 85°C under rated ripple current.
• Leakage and Insulation Characteristics — Leakage current after 5 minutes not more than 3√(C·V) µA or 5 mA (whichever smaller); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket (per datasheet).
• Safety and Durability Tests — Voltage proof test: no abnormality during AC 2500 V for 1 minute between terminal and bracket; endurance and shelf-life criteria per datasheet requirements.
• Compliance — RoHS compliant.
• Form Factor — Smaller-sized series construction with dimensions L: 11.5 cm × D: 6.35 cm and screw-terminal radial package for compact power module integration.

Typical Applications

• Power supply filtering — Bulk decoupling and smoothing in DC power supplies where 400 V rating and high ripple current are required.
• Energy buffering — Short-term energy storage in power conversion modules that need a combination of high capacitance and robust ripple handling.
• Industrial power electronics — General-purpose use in industrial power assemblies that operate within −25°C to +85°C and demand long-life capacitors.

Unique Advantages

• High energy density at high voltage — 3900 µF at 400 V provides substantial charge storage for compact power designs.
• Designed for high ripple environments — Specified ripple-current ratings at both low and high frequencies allow confident selection for AC ripple-heavy circuits.
• Long operational life — 5000 hours at 85°C under rated ripple current supports extended duty in continuous-power applications.
• Robust connections — Screw-terminal construction ensures secure electrical and mechanical connections for power assemblies.
• Tested electrical reliability — Leakage, insulation resistance, and voltage-proof values are specified in the datasheet for predictable performance.
• Regulatory compliance — RoHS compliant to support regulatory requirements for restricted substances.
