Low Ohm Resistor

A resistor paste which produces a stable, high-yield, one ohm/cm2 resistor can be produced as follows: 60:40 ) 32.4% Ag )

ratio ) 21.6% Pd )

of fine) 2.0% lead borosilicate glass ) 60% solids

powder ) 4.0% colloidal silica )

40.0% organic vehicle, for example, higher

boiling paraffins, cycloparaffins, aromatic

hydrocarbons, cellosolve or carbitols such

as butyl carbitol acetate, with polymeric

thickness such as cellulosic compounds or

the like.

The resistor paste is screened through 325-200 mesh and is fired at 750 degrees C. The temperature coefficient of resistivity of the fired resistor is about 2 1/2% from 25 degrees C to 125 degrees C. The exact resistance can be altered by changing the solids percentage or thickness of the deposit.
