The 1206 (3216 Metric) surface-mount package and 8 Ohm ESR make it a general-purpose choice for decoupling, filtering, and timing circuits in designs that need stable capacitance over temperature. The 8 Ohm ESR is higher than modern low-ESR tantalums — budget extra ripple margin if used near a switching regulator output.
1206 (3216 Metric) case, size code A, seated height 1.80 mm max. The molded construction gives good mechanical protection during reflow and handling. No derating is required at 85°C, but at 125°C the applied voltage should stay below 2/3 of rated voltage per typical tantalum application guidelines.
