The 556FSR300XHBC is a radial lead aluminum electrolytic capacitor designed for photoflash applications, rated at 300 WVDC with a capacitance of 55 µF. It has a maximum ESR of 1.608 Ω at 120 Hz and 20°C, and dimensions of 12 mm in diameter and 14 mm in length. The capacitor satisfies JIS 2365 compliance, operates within a temperature range of -20°C to +55°C, and exhibits a dissipation factor of 0.06 at 120 Hz and 25°C. Leakage current at 25°C after 5 minutes is specified as 1 × rated voltage. It supports 5000 flash cycles at rated voltage through a 0.7-1.0 Ω discharge resistance, with capacitance change under 10% and dissipation factor and leakage current each under 150% of maximum specified values after stress tests. Shelf life performance after 500 hours at 55°C with no voltage applied meets the same stability criteria.
