LNK2H122MSEFBB

The LNK2H122MSEFBB is a screw-terminal aluminum electrolytic capacitor in the Nichicon LNK series, designed for high-voltage, high-capacitance general-purpose applications. It delivers 1.2 mF at a 500 V rating in a radial can with screw terminals, offering robust energy storage and filtering for industrial and power-electronics systems.

Engineered for sustained operation, this capacitor is specified for operation from -25 °C to +85 °C and a 5000-hour load life under rated ripple at 85 °C, providing predictable performance in demanding environments.

Key Features

• High Capacitance & Voltage: 1.2 mF (1200 µF) nominal capacitance at a 500 V rated voltage for bulk energy storage and smoothing in high-voltage rails.
• Screw Terminal Mounting: Radial can with screw terminals simplifies mechanical retention and high-current connections for power supplies and DC bus applications.
• Load Life and Endurance: Rated for 5000 hours with DC bias plus rated ripple current at 85 °C; after recovery to 20 °C, capacitance change remains within ±20% of initial value.
• Ripple Current Capability: Rated ripple current of 6.2 A at 120 Hz and 8.68 A at 10 kHz, supporting AC ripple handling across common switching and mains frequencies.
• Temperature Performance: Operating range from -25 °C to +85 °C with a maximum impedance ratio Z(-25 °C)/Z(+20 °C) of 8, ensuring defined low-temperature behavior.
• Leakage and Insulation Characteristics: Leakage current after 5 minutes is limited to 3√(C·V) µA or 5 mA (whichever is smaller) at 20 °C; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Proof: Verified to withstand AC 2500 V for 1 minute between terminal and bracket with no abnormality.
• RoHS Compliance and Marking: Compliant with RoHS (2011/65/EU, (EU)2015/863) and marked with white lettering on a black sleeve for clear identification.
• Physical Dimensions & Package: Canonical radial can package with overall size L: 11.5 × D: 5.1 cm, designed for secure screw-terminal installation.

Typical Applications

• Power Supply Filtering: Bulk smoothing and ripple reduction in high-voltage DC power supplies and converters.
• DC Bus Energy Storage: Energy buffering and stabilization on DC buses in industrial power systems and large inverters.
• Power Electronics: Support for switching supplies and motor drives where high-voltage, high-capacitance components are required for reliable operation.

Unique Advantages

• High-Voltage Energy Density: 1.2 mF at 500 V supplies significant energy storage in a compact radial-can package for space-constrained high-voltage designs.
• Robust Mechanical Connection: Screw terminals provide secure, low-resistance connections suitable for repeated maintenance and high-current paths.
• Defined Lifetime Performance: 5000-hour rated endurance at 85 °C under ripple conditions gives designers quantifiable long-term behavior for reliability planning.
• Frequency-Responsive Ripple Handling: Published ripple current values at 120 Hz and 10 kHz allow designers to size capacitors against expected switching and mains-frequency ripple loads.
• Clear Qualification Metrics: Leakage, insulation resistance, and voltage-proof specifications provide measurable acceptance criteria for incoming inspection and system qualification.
• Regulatory Compliance: RoHS conformity supports use in regions requiring restricted-substance compliance.
