LNX2H123MSEKBN

The LNX2H123MSEKBN is an aluminum electrolytic, screw-terminal capacitor designed for high-voltage, high-ripple power electronics. As a radial can with screw terminals, it provides bulk energy storage and smoothing for demanding industrial power supplies and inverter circuitry.

Engineered for high ripple current and extended life at elevated temperature, this 12,000 µF, 500 V polarized capacitor is targeted at applications that require robust DC-link performance and reliable long-term operation up to +85°C. The part is RoHS compliant.

Key Features

• High Capacitance: 12,000 µF of bulk capacitance suitable for DC-link and smoothing applications requiring substantial energy storage.
• Extra-High Voltage Rating: Rated at 500 V to support high-voltage power conversion and inverter boards.
• High Ripple Current Handling: Rated ripple current of 27.8 A at 120 Hz and 38.92 A at 100 kHz to support heavy AC ripple and switching environments.
• Endurance at Elevated Temperature: Specified endurance for 500 V parts is 5,000 hours at +85°C under rated ripple/biased conditions; series-level endurance includes up to 20,000 hours at +85°C for lower-voltage variants.
• Robust Mounting: Screw terminal, radial can package provides secure, low-impedance connections for high-current power assemblies.
• Operating Range: Rated for operation from −25°C to +85°C, with a capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Compliance: RoHS directive compliant (2011/65/EU, (EU)2015/863).
• Form Factor: Large-package dimensions (Height seated max: 8.661 in; nominal size L: 22 × D: 10 cm) for high-energy-density installations.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage for high-voltage industrial supplies and inverter front-ends.
• Inverter and Motor Drive DC-Link: DC-link smoothing for inverter circuitry where high ripple current and 500 V rating are required.
• High-Voltage Power Conversion: Energy buffering and ripple suppression in high-voltage converters and power modules.

Unique Advantages

• Large Energy Reserve: 12,000 µF capacitance provides significant bulk storage to stabilize DC rails and absorb transient loads.
• High-Voltage Capability: 500 V rating enables use in extra-high-voltage power architectures without series stacking.
• Designed for High Ripple: High rated ripple currents at both low and high frequencies reduce heating and extend service life in switching environments.
• Durability at Elevated Temperature: Specified endurance of 5,000 hours at +85°C for 500 V parts supports long-term reliability under heavy duty operation.
• Secure Screw-Terminal Connections: Screw terminals deliver robust mechanical and electrical connections suitable for high-current assemblies.
• Regulatory Compliance: RoHS compliance supports deployment in designs requiring restricted-substance conformity.
