Molded tantalum, 6.8 µF at 10 V — 1206 footprint
The TPSA685K010R1800 is a molded tantalum capacitor from KYOCERA AVX's TPS series, delivering 6.8 µF capacitance with ±10% tolerance at a 10 V rated voltage. The 1.8 Ohm ESR (equivalent series resistance) sets the ripple-current handling and self-heating floor — for a 10 V rail decoupling application, the ESR limits the capacitor's ability to absorb high-frequency ripple without temperature rise.
