LNX2J122MSEH

The LNX2J122MSEH is an aluminum electrolytic, screw-terminal capacitor from Nichicon's LNX series. It provides 1.2 mF (1200 µF) capacitance at a 630 V rating in a radial can with M5 screw terminals, designed for polarized, general-purpose power-electronics use.

Engineered for high-voltage, high-ripple environments, this part addresses industrial power supply and inverter circuitry needs while offering RoHS compliance and a specified lifetime of 2000 hours at +85°C.

Key Features

• Electrical Performance — 1.2 mF capacitance with a capacitance tolerance of ±20% (–20% to +20%), and a rated voltage of 630 V for extra-high-voltage applications.
• High Ripple Capability — Specified ripple handling of 6.7 A at 120 Hz and 9.38 A at 100 kHz to support demanding power-electronics filtering and smoothing tasks.
• Lifetime & Temperature — Rated for operation from –25 °C to +85 °C with a specified lifetime of 2000 hours at +85 °C.
• Mechanical & Mounting — Radial can package with screw terminals (M5 nominal bolt) for secure, low-resistance connections and straightforward installation.
• Polarized Design — Polarized capacitor architecture for DC link, smoothing, and energy-storage applications where polarity is defined.
• Compliance — RoHS compliant, meeting environmental directive requirements listed in the product data.
• Form Factor — Physical size: diameter 76.2 mm × length 110 mm; cardboard packing.

Typical Applications

• Industrial Power Supplies — Used in inverter and industrial power-supply circuits for bulk energy storage and ripple suppression at high voltages.
• Power Conversion — Suitable for DC-link smoothing and filtering in high-voltage converters where sustained ripple handling is required.
• General-Purpose Power Electronics — Applicable where a polarized, screw-terminal capacitor with a 630 V rating and robust ripple capability is needed.

Unique Advantages

• Extra-high Voltage Rating: 630 V rating enables use in higher-voltage power systems without series stacking.
• Documented Ripple Performance: Explicit ripple current specifications at 120 Hz and 100 kHz allow accurate thermal and reliability planning.
• Screw-Terminal Reliability: M5 screw-terminal connections provide secure mechanical and electrical attachment for heavy-current applications.
• Compact Radial Can: φ76.2 mm diameter in a radial can simplifies integration into power assemblies while maintaining required capacitance.
• Regulatory Compliance: RoHS compliance supports designs targeting regulated markets and environments.
