LNX2W183MSEK

The LNX2W183MSEK is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for high‑voltage, high‑ripple applications. It delivers 18,000 µF capacitance at a 450 V rating and is polarized for DC use.

Engineered for industrial power electronics, the part offers extended operational life—specified at 20,000 hours at +85°C under rated ripple conditions—and is supplied in cardboard packing for mass production handling.

Key Features

• Capacitance & Voltage: 18,000 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance for high‑energy storage in high‑voltage circuits.
• Long Endurance: Rated for 20,000 hours at +85°C under standard ripple current, with endurance limits specifying capacitance change within ±20% and leakage current within initial specified values after test.
• High Ripple Capability: Specified ripple currents of 37 A at 120 Hz (low frequency) and 51.8 A at 100 kHz (high frequency) to support demanding power conversion loads.
• Mechanical & Termination: Screw terminal radial can package (φ100 × 250L size); series documentation indicates M8 nominal bolt for φ100 terminals for robust electrical and mechanical connection.
• Operating Range: Polarized capacitor with an operating temperature range of −25°C to +85°C suitable for typical industrial ambient conditions.
• Leakage & Quality: Leakage current specification: after 5 minutes’ application of rated voltage, not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C), supporting predictable performance during startup.
• Regulatory: RoHS compliant as supplied in the product information and datasheet.

Typical Applications

• Industrial power supplies: Bulk energy storage and smoothing in industrial power supply front ends where high voltage and long life are required.
• Inverter circuitry and motor drives: DC link and ripple handling for inverter sections and motor‑drive power stages that demand high ripple current capability.
• General purpose high‑voltage systems: Use in general purpose industrial equipment that requires a polarized, high‑voltage electrolytic capacitor with extended endurance.

Unique Advantages

• Extended rated life: 20,000 hours at +85°C under rated ripple current reduces service interval frequency and supports long equipment uptime.
• High ripple tolerance: Dual ripple current specifications (37 A @ 120 Hz, 51.8 A @ 100 kHz) enable effective use across a range of switching and line frequencies.
• High voltage capability: 450 V rating supports extra‑high voltage power conversion stages without series stacking.
• Robust screw‑terminal package: Radial can with screw terminals and φ100 × 250L form factor provides solid mechanical mounting and low‑impedance connections for high current paths.
• Measured leakage control: Defined leakage current limits (3√CV µA or 5 mA after 5 minutes) help ensure predictable charging characteristics during commissioning.
• RoHS compliant supply: Environmentally compliant construction suitable for regulated manufacturing environments.
