LNK2H122MSEG

The LNK2H122MSEG is a polarized aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose high-voltage power applications. It provides 1.2 mF capacitance at a 500 V rating in a compact, smaller-sized LNK series package optimized for screw-terminal mounting and robust electrical connections.

Key value comes from its high ripple-current capability, long load life at elevated temperature, and a temperature range that supports typical industrial environments.

Key Features

• Electrical Capacity — 1.2 mF (1200 µF) nominal capacitance with a tolerance of ±20% (–20% to +20%).
• High Voltage Rating — Rated for 500 V DC to support high-voltage smoothing and energy-storage roles in power systems.
• High Ripple Current — Specified ripple current of 6.3 A at 120 Hz and 8.82 A at 10 kHz for demanding AC ripple environments.
• Reliability & Endurance — Load-life rating of 5000 hours at 85°C with rated ripple current applied; capacitance change remains within ±20% after endurance testing.
• Thermal Range — Operating temperature range from –25°C to +85°C for broad environmental compatibility.
• Leakage & Insulation — Leakage current after 5 minutes is limited to 3√(C·V) μA or 5 mA (whichever is smaller); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Mechanical & Mounting — Radial can with screw terminals for secure, low-resistance connections; printed marking in white on black sleeve for clear identification.
• Safety Checks — Withstands AC 2500 V for 1 minute between terminal and bracket without abnormality (voltage proof test).

Typical Applications

• High-voltage power supplies — Bulk energy storage and smoothing where a 500 V rated electrolytic capacitor is required.
• Industrial power electronics — Filtering and ripple suppression in equipment that needs robust screw-terminal connections and high ripple-current capability.
• General-purpose DC systems — Use in general-purpose circuits that benefit from polarized, high-capacitance components with long load life at elevated temperature.

Unique Advantages

• High-voltage capability: 500 V rating enables use in higher-voltage DC rails without series stacking.
• Designed for high ripple environments: Specified ripple current at both low (120 Hz) and high (10 kHz) frequencies to address real-world power-line and switching noise.
• Robust endurance: 5000 hours at 85°C with endurance specifications that keep capacitance within ±20%, supporting longer maintenance intervals.
• Secure screw-terminal mounting: Radial can with screw terminals provides reliable mechanical and electrical connections for heavy-current or serviceable installations.
• Clear identification and handling: White printing on a black sleeve for easy visual verification during assembly and maintenance.
