MINI-BLOK MINIATURE RECTANGULAR METAL FILM RADIAL LEAD PRECISION RESISTOR
Abstract
Efforts were made to develop a plus or minus .05% miniature metal film resistor which should have a maximum volume of 5 x 1/10,000 cubic inches in a rectangular configuration with radial leads. The resistor shall be rated at 1/10 watt at 85 C ambient in ranges from 100 to 200,000 omega. Evaluation of Mycalex, Steatite, and Alumina substrates was completed, and Alumina was selected.A preliminary layout for evaporation was worked out. The ceramics are placed on a rotary heater with a filament source at a 60 degree angle from the horizontal plane of the heater. Design work was also done on substrate heaters, spray masks for gold termination, leads and tooling, molding, and an adjusting device. (Author)
