ABSTRACT:
In a noble-metal containing resistor paste, there is added a quantity of colloidal aluminum oxide hydroxide (AlOOH) in order to make an upward adjustment in the TCR of the fired resistor film. The additions of AlOOH have only a small effect on the resistivity and usually causes a downward change in the resistivity value.
