LNK2H122MSEGBB

The LNK2H122MSEGBB is an aluminum electrolytic capacitor in a radial can with screw terminals, rated at 1.2 mF (1200 µF) and 500 V. It is a polarized, smaller-sized capacitor designed for general-purpose applications that require high-voltage capacitance in a secure screw-terminal package.

This part delivers high ripple-current capability and long-term endurance—5000 hours load life at 85 °C under rated ripple conditions—while meeting RoHS requirements for supplier compliance.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) rated at 500 V for high-voltage energy storage needs.
• Screw Terminal Package: Radial can with screw terminals provides robust, low-impedance connections for high-current circuits.
• High Ripple Current: Rated ripple current of 6.3 A at 120 Hz and 8.82 A at 10 kHz for demanding AC ripple conditions.
• Long Load Life: Endurance specified as 5000 hours at 85 °C under D.C. bias plus rated ripple current.
• Operating Temperature: Specified operating range from -25 °C to +85 °C for broad environmental compatibility.
• Reliability Characteristics: Leakage current specified as not more than 3√CV (µA) or 5 mA after 5 minutes at 20 °C; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Compliance & Size: RoHS compliant and offered in a smaller-sized configuration with dimensions L: 8.5 × D: 6.35 cm.
• Polarized Design: Intended for DC applications where a polarized electrolytic capacitor is required.

Typical Applications

• General-purpose electrical systems: Use where a 500 V rated, 1200 µF polarized capacitor with screw terminals is required for high-voltage capacity in a compact footprint.
• High-ripple circuits: Suitable for circuits that see significant ripple currents, leveraging the specified 6.3 A (120 Hz) and 8.82 A (10 kHz) ripple capabilities.
• Long-life, elevated-temperature installations: Systems that demand stable capacitance over extended periods at up to 85 °C can utilize the 5000-hour load-life rating.

Unique Advantages

• High-voltage capability: 500 V rating enables fewer series capacitors where high DC voltage support is required.
• High ripple tolerance across frequencies: Explicit ripple ratings at both 120 Hz and 10 kHz demonstrate predictable performance at low and high ripple frequencies.
• Extended operational endurance: 5000-hour load-life at 85 °C provides measurable long-term durability under rated conditions.
• Secure screw-terminal connections: Screw terminals provide robust mechanical and electrical connections for higher-current paths compared with leaded options.
• Measured leakage and insulation specs: Defined leakage current limits and insulation resistance (>100 MΩ at DC 500 V) support predictable behavior in DC-biased applications.
• RoHS compliant: Conforms to RoHS directive for environmental compliance.
