THE METHOD OF MAKING A CAPACITOR-RESISTOR CONSTRUCTION COMPRISING THE STEPS OF CONVOLUTELY WINDING ELECTRODE FOILS AND PLASTIC DIELECTRIC FILMS TO PROVIDE A COILED CAPACITOR BODY WITH EXPOSED ELECTRODE FOIL EDGE PORTIONS AT EACH END OF SAID BODY PORTION AND WITH THE OUTERMOST CONVOLUTION OF SAID BODY BEING OF DIELECTRIC MATERIAL, APPLYING LEADS TO EACH END OF SAID BODY TO CONTACT AND TRAVERSE A PLURALITY OF THE ELECTRODE FOIL EDGE PORTIONS TO FORM AN ELECTRICAL CONNECTION THEREWITH, THEREAFTER APPPLYING A CARBON RESIN MATERIAL HAVING RESISTIVE CHARACTERISTICS DIRECTLY TO THE OUTER SURFACE OF SAID OUTER CONVOLUTION OF DIELECTRIC MATERIAL WITH SUFFICIENT PORTIONS OF SAID RESISTIVE MATERIAL CONTACTING THE EXPOSED ELECTRODE FOIL EDGE PORTIONS OF SAID CAPACITOR BODY TO THERMALLY AND ELECTRICALLY CONNECT THE RESISTIVE MATERIAL TO THE ELECTRODE FOIL EDGE PORTIONS WITH PORTIONS OF SAID RESISTIVE MATERIAL BEING THERMALLY AND ELECTRICALLY CONNECTED WITH SAID LEADS, THEREBY TO FORM AT LEAST ONE CAPACITOR CONNECTION AND AT LEAST ONE RESISTOR CONNECTION TO SAID LEADS ACCOMPLISHING DISSIPATION OF HEAT THROUGHOUT THE CAPACITORRESISTOR BODY TO ASSURE RELATIVELY UNIFORM FUNCTIONING THEREOF.
