smd resistors fcr, rca, rcn series

smd resistors fcr, rca, rcn series

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 precision smd (fcr), smd array (rca), and networks (rcn).
