This part issuitable for wave or IR reflow soldering.Green coatA low TCR resistance alloy plate is grooved to set the final resistance, the lower faces are tin plated forconnections, and itisprotectively coated onthe upper and lower faces and numerically marked with the resistancevalue. This part isONLY suitable for IR reflow soldering.UncoatedAlow TCR resistance alloy plate isgrooved to set the final resistance and the lower face only is protected with anepoxy coating. The lower faces are tin plated for connections. This part is ONLY suitable for IRreflow soldering.MarkingOnly 2512 size parts are marked. For values which are integer numbers of milliohms, the marking is 4-characterIEC62 code; e.g. “R002” for 2m ,“R010” for 10m .For values including fractions of amilliohm the marking is 3or4-character code using “M” to indicate the decimal point, e.g. “M75” for 0.75m ,“1M50” for 1.5m .Ni PlatingBlackSn Plated FinishGreen Coat &UncoatedTermination Details:MaterialMatt tin plated finish over abarrier layerSolderability 95% min coverage (MIL-STD 202F /208H, 235ºC 2 secs)AEC-Q200 Table 7ref.TestMethodMax.
