X5R dielectric offers stable capacitance over -55 to 85C. DC bias at 3.3V reduces effective capacitance by ~40-50%.","working_principle":"Thin X5R barium titanate dielectric layers with alternating nickel inner electrodes stacked and co-fired. The 0805 footprint balances compact size with sufficient ceramic volume for 22uF at 10V. DC bias effect reduces effective capacitance proportional to applied voltage.","pin_description":"
