LNK2G122MSEFBB

The LNK2G122MSEFBB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose high-voltage applications. It delivers 1,200 µF capacitance at a 400 V rating in a radial can with screw terminals, combining high ripple-current capability with long operational life.

Engineered for use where robust DC bus filtering and energy smoothing are required, this RoHS-compliant capacitor offers a balance of voltage handling, ripple performance, and endurance for industrial and power-electronics designs.

Key Features

• Capacitance & Tolerance — 1.2 mF (1200 µF) capacitance with ±20% tolerance (–20%~20%).
• Voltage Rating — Rated at 400 V for high-voltage DC applications within the series' 350–500 V range.
• Screw Terminal Package — Radial can with screw terminals for secure, low-resistance connections and straightforward assembly.
• Operating Temperature & Endurance — Specified for −25 °C to +85 °C with a load life of 5000 hours at 85 °C under rated ripple current.
• High Ripple Current — Rated ripple current of 5.8 A at 120 Hz and 8.12 A at 10 kHz, supporting demanding AC ripple and switching environments.
• Reliability and Insulation — Insulation resistance greater than 100 MΩ at DC 500 V (between terminal and bracket) and voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C), per the series datasheet.
• Physical Footprint — Compact radial can: length 7.5 cm × diameter 5.1 cm, with a maximum seated height of 2.953 inches for board- or chassis-mounted installations.
• Regulatory — RoHS compliant.

Typical Applications

• High‑voltage Power Supplies — 400 V rating and substantial capacitance provide bulk filtering and energy storage on DC buses and high-voltage rails.
• Industrial Power Conversion — Screw-terminal construction and high ripple-current capability suit rectifier smoothing and intermediate DC link applications.
• UPS and Backup Systems — Long load life at elevated temperature and strong insulation characteristics support energy-hold and smoothing roles in backup power designs.

Unique Advantages

• High ripple-current handling: 5.8 A at 120 Hz and 8.12 A at 10 kHz reduce temperature rise under AC stress and help maintain performance in switching environments.
• Long operational life: 5000 hours at 85 °C under rated ripple current supports dependable service in continuous-duty applications.
• Secure screw-terminal mounting: Facilitates robust electrical connection and easy integration into chassis- or bracket-mounted power assemblies.
• High-voltage capability: 400 V rating enables use on higher-voltage DC buses without additional stacking or series arrangements.
• Verified insulation and voltage proof: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V 1-minute voltage proof ensure component-level safety margins between terminal and bracket.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
