Abstract:

Research continued on the fixed film type resistors. The following conclusions were reached At 175 C no-load, resistive film contributes the bulk of Delta R rather than termination. Performance is related to base range the higher the base range, the higher the Delta Rs. PC-29 overcoat minimizes Delta R on all base rangesAS COMPARED TO NON-OVERCOATED UNITS. The maximum base range for this resistor will be between 3 and 5 Kilohms. CP40S type termination material is superior to CP40D on units 300 ohms and lower. Silver migration is not a problem with this resistor. The filament cutting, trim-paint and molding operations now operate satisfactorily. The materials used for this resistor do not have the capability of performing at 175 C no-load within specification limits. Author
