THIN-FILM PRECISION CHIP RESISTOR Russian patent published in 1998 - IPC

FIELD: electronic engineering; manufacture of fixed precision chip resistors. SUBSTANCE: resistor has insulating base covered with resistive ceramic film, contact members, and protective coating directly deposited onto resistive film between contact members; protective coating is made of silicone material of alkylalkoxysilane series whose entire resistor effective surface is covered in addition with epoxy-phenol material. Protective coating provides for using chip resistor at relative humidity as high as 93 3%, temperature of 20 C, and electric load R = 0.01 of rated value. EFFECT: improved moisture resistance and provision for dispensing with additional encapsulation of resistor. 1 dwg, 1 tbl
