LNK2G222MSEG

The LNK2G222MSEG from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNK series, rated at 2.2 mF (2200 µF) and 400 V. It is a polarized, radial can design intended for general-purpose applications that require high-voltage bulk capacitance and secure screw-terminal connections.

Key attributes include a -25 °C to 85 °C operating range, a load life of 5000 hours at 85 °C under rated ripple conditions, and construction sized at φ63.5 × 85L (approx. L: 8.5 × D: 6.35 cm), providing a compact high-voltage energy-storage solution.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) at 400 V for bulk energy storage and filtering in high-voltage circuits.
• Screw-Terminal Mounting: Radial can with screw terminals provides reliable, low-impedance connections for high-current applications.
• Operating Temperature & Life: Rated for -25 °C to 85 °C with a specified load life of 5000 hours at 85 °C under DC bias plus rated ripple current.
• Ripple Current Capability: Rated ripple current of 8.9 A at 120 Hz and 12.46 A at 10 kHz, with frequency coefficients provided for other operating frequencies.
• Electrical Loss & Leakage: Specified tan δ of 0.2 and measured leakage current of 2810 µA (as provided for this part).
• Safety & Insulation: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and voltage-proof performance under AC 2500 V for 1 minute (no abnormality).
• RoHS Compliance: Compliant with RoHS directive as provided in the product information.

Typical Applications

• General-purpose power filtering: Bulk smoothing and energy storage in high-voltage power supplies where 400 V, 2200 µF capacitance is required with robust screw-terminal connections.
• High-voltage DC link buffering: Energy buffering and ripple reduction in DC bus circuits benefitting from the capacitor’s rated ripple current and 5000-hour life at 85 °C.
• Industrial power electronics: Use in general-purpose industrial equipment that needs a polarized, high-voltage capacitor with secure mechanical and electrical terminal attachment.

Unique Advantages

• High-voltage capability: 400 V rating enables use in circuits requiring elevated DC voltages without series stacking.
• Long load life: 5000 hours at 85 °C under rated ripple conditions supports extended field service life in continuous-duty applications.
• Screw-terminal reliability: Mechanical screw terminals deliver secure, low-resistance connections suited to high-current and vibration-prone environments.
• Measured ripple performance: Published ripple current values at 120 Hz (8.9 A) and 10 kHz (12.46 A) allow designers to size the capacitor based on frequency-specific ripple demands.
• Controlled leakage and loss: Specified leakage current (2810 µA) and tan δ (0.2) enable predictable behavior for charge/discharge and impedance budgeting.
• Regulatory compliance: RoHS compliance supports environmental and materials requirements for modern equipment designs.
