LNX2W822MSEJ

The LNX2W822MSEJ is a screw-terminal aluminum electrolytic capacitor designed for high-voltage, high-ripple industrial power applications. It is a polarized, radial can-type capacitor offering 8,200 µF capacitance at a 450 V rating and is optimized for long life under rated ripple conditions.

Targeted at industrial power supplies and inverter circuitry, this part delivers high ripple-current capability and extended endurance for demanding power-conversion environments while remaining RoHS compliant.

Key Features

• Capacitance & Voltage — 8,200 µF nominal capacitance with a rated voltage of 450 V and a capacitance tolerance of -20% to +20%.
• High Ripple Current — Handles 19.8 A at 120 Hz (low frequency) and 27.72 A at 100 kHz (high frequency), supporting heavy AC ripple in power supplies and converters.
• Long Endurance — Rated for 20,000 hours life at +85°C under standard ripple-current conditions, enabling extended field service in continuous-duty systems.
• Thermal Range — Operational temperature range from -25°C to +85°C, suitable for a wide range of industrial ambient conditions.
• Leakage & Dissipation — Specified leakage current of 5,000 µA and tan δ (DF) of 0.2 measured at 20°C, 120 Hz, for predictable loss behavior.
• Robust Mechanical Package — Screw terminal radial can package (φ90 × 170L) designed for secure bolted connections; terminal hardware for φ90 size uses M5 nominal bolt diameter.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Power Supplies — Energy smoothing and bulk storage for high-voltage power rails in industrial converters and supply modules.
• Inverter Circuitry — DC-link and ripple absorption in inverter systems where sustained ripple current handling and long life are required.
• High-Voltage Power Conversion — Filtering and energy buffering in extra‑high voltage assemblies within the 350–550 V rated range supported by the LNX series.
• General Purpose Power Systems — Bulk capacitance and smoothing in heavy-duty power electronics and industrial control equipment.

Unique Advantages

• High ripple capability: The LNX2W822MSEJ supports 19.8 A (120 Hz) and 27.72 A (100 kHz) ripple currents, reducing the need for parallel components to share ripple stress.
• Extended operational life: 20,000 hours at +85°C under rated ripple conditions provides long-term reliability for continuously operating systems.
• High-voltage suitability: 450 V rating and series support up to 550 V enable use in extra-high-voltage power designs.
• Secure screw-terminal mounting: Radial can with screw terminals and M5 nominal bolt accommodation (for φ90 size) ensures robust electrical and mechanical connections.
• Predictable electrical behavior: Specified tan δ and leakage current figures measured at standard conditions give designers clear performance expectations for loss and leakage.
• Regulatory compliance: RoHS compliance supports deployment in regulated industrial and commercial products.
