Thin film precision resistance and network

1.1.Product description
Precision thin film resistance (resistance network) is a chip thin film resistance (resistance network) with high resistance value tracking accuracy and small volume. It has the advantages of high resistance value precision, low resistance temperature coefficient, low noise and good long-term stability. It is suitable for the fields of aerospace, aviation and implantation of human medical devices. The precision can be up to 0.01%, the temperature tracking coefficient up to 0.02%, and arbitrary resistance values can be customized according to customer requirements, and the packaging can be in the form of chip table sticker, ceramic package, package package, etc.
