The 157FSL450XDG is a 150 µF aluminum electrolytic photoflash capacitor rated for 450 V DC with a dissipation factor of 0.774062 at 120 Hz and 20°C, and an ESR of 779.42 Ω. It measures 30 mm in diameter and 45 mm in length, and is designed for applications requiring high reliability under repeated flash conditions. The capacitor operates within a temperature range of -20°C to +70°C and maintains capacitance change under 10% after 1 million flashes at rated voltage and 45°C. It meets shelf life requirements with no voltage applied for 500 hours at 70°C, with leakage current and dissipation factor within specified limits.
