LNK2G222MSEGBB

The LNK2G222MSEGBB is a Nichicon LNK-series aluminum electrolytic capacitor in a screw-terminal radial can. It delivers 2.2 mF capacitance at a 400 V rating in a compact screw-terminal package sized for higher-voltage power applications.

Designed for general-purpose high-voltage use, the part combines a 5000-hour endurance at 85°C with defined ripple-current capability and controlled leakage characteristics to support robust DC-link and filtering functions in industrial and power-electronics equipment.

Key Features

• Capacitance & Tolerance — 2.2 mF (2200 µF) nominal with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and filtering.
• High Voltage Rating — Rated voltage 400 V for use in high-voltage DC circuits and power modules.
• Endurance & Temperature — Rated lifetime of 5000 hours at 85°C; operating temperature range −25°C to +85°C to match elevated-temperature ripple applications.
• Leakage Current Specification — Specified leakage current of 2810 µA; the series datasheet defines the leakage test as after 5 minutes' application of rated voltage at 20°C (≤ 3√CV µA or 5 mA, whichever is smaller).
• Ripple Current Performance — Ripple capability specified as 8.9 A at 120 Hz and 12.46 A at 10 kHz to support AC ripple handling across frequencies.
• Screw Terminal Package — Radial can with screw terminals (nominal bolt M5 for φ63.5 size) for secure mechanical and electrical connections in chassis-mounted or bracketed assemblies.
• Compact Dimensions — Physical size φ63.5 × 85L (size: L: 8.5 × D: 6.35 cm) to fit space-constrained power assemblies while providing high voltage and capacitance.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• High-voltage DC filtering — Use the 400 V rating and 2.2 mF capacitance for smoothing and decoupling in high-voltage DC buses and power supplies.
• DC-link and energy buffering — The combination of capacitance, ripple-current rating, and 5000-hour endurance at 85°C supports energy storage and DC-link roles in industrial power electronics.
• Industrial equipment power modules — Screw-terminal mounting and robust dimensions suit chassis- or bracket-mounted power modules that require secure electrical connections.

Unique Advantages

• High-voltage capability: 400 V rating enables use in circuits requiring elevated DC voltages without series stacking.
• Long rated life at temperature: 5000-hour endurance at 85°C provides predictable performance in sustained high-temperature ripple environments.
• Measured ripple performance: Specified ripple currents at 120 Hz and 10 kHz help designers assess thermal and life trade-offs across frequency ranges.
• Secure screw-terminal connection: M5-compatible screw terminals and radial can packaging simplify installation and maintenance in power assemblies.
• Defined leakage behavior: Leakage current is specified (2810 µA) and the datasheet provides the measurement criteria, aiding in thermal and standby-loss budgeting.
• RoHS compliant: Meets lead-free environmental requirements for contemporary designs.
