AR, FCR, RCA, RCN Series are formed by vacuum depositing a resistive
alloy on a usually flat substrate of ceramic. Photo-lithographic or
similar techniques are used to define the final geometry and interconnecting
traces. This technology provides for close ratio matching and tracking
in a network, as well as low stand-alone temperature coefficient and
resistance tolerance. Types includes ultra precision (AR), precision (FCR), array (RCA), and networks (RCN). |
