Abstract:High tolerance chip capacitors are at best expensive and at the worst unobtainable. When asked to custom build a small signal circuit containing close tolerance RC networks it became obvious that functional resistor trimming was unavoidable if suitable quantities were to be produced at the right price.The product which is shown in Figure is constructed by conventional thick film techniques. It uses a l"x 2" alumina substrate and attached com- 2) The majority of the resistors are trimmed prior to the attachme… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
