• High Ripple Current: Rated ripple current of 32.4 A at 120 Hz and 45.36 A at 100 kHz, enabling effective smoothing under heavy ripple conditions.
• Long Life Endurance: Specified for 20,000 hours of rated ripple-current operation at +85°C, supporting sustained duty in demanding installations.
• Temperature Range & Stability: Operating temperature from −25°C to +85°C; impedance ratio Z(−25°C)/Z(+20°C) of 8 for low‑temperature stability.
• Screw Terminal Package: Radial can with screw terminals for secure, high-current connections in power assemblies.
• Safety & Materials Options: Flame‑retardant electrolyte versions available; leakage current limited by the specification 3√CV (µA) or 5 mA after 5 minutes at 20°C.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk capacitance and high ripple current capability make this capacitor suitable for smoothing and energy buffering in industrial supply modules.
• Inverter Circuits: Engineered for inverter circuitry where extra‑high voltage and sustained ripple handling are required.
• Extra‑High‑Voltage Systems: Suited for applications calling out extra‑high voltage performance within the series' rated range.
• General‑Purpose Power Filtering: Polarized, high-capacitance filtering for DC link and power conversion stages in heavy-duty assemblies.

Unique Advantages

• High ripple tolerance: Explicit ripple ratings at both low and high frequencies (32.4 A at 120 Hz; 45.36 A at 100 kHz) reduce thermal stress and improve reliability in high‑ripple environments.
• Extended operational life: Qualified for 20,000 hours at +85°C under rated ripple current, supporting long maintenance intervals and predictable lifespan planning.
• Robust, secure mounting: Screw-terminal radial-can construction provides solid electrical and mechanical connections for high-current power assemblies.
• Low-temperature performance: Measured impedance stability with Z(−25°C)/Z(+20°C) = 8 helps maintain performance across the specified −25°C to +85°C range.
• Series scalability: Part of the LNX family with an extended size range (up to φ100 = 250L), allowing designers to select compatible sizes across similar performance classes.
• Regulatory compliance: RoHS conformity and available flame‑retardant electrolyte options support regulatory and safety considerations.
