This part is suitable for wave or reflow soldering. Green coat A low TCR resistance alloy plate is grooved to set the final resistance, the lower faces are tin plated for connections, and it is protectively coated on the upper and lower faces and numerically marked with the resistance value. This part is ONLY suitable for reflow soldering. Uncoated A low TCR resistance alloy plate is grooved to set the final resistance and the lower face only is protected with an epoxy coating. The lower faces are tin plated for connections. This part is ONLY suitable for reflow soldering. Marking Only 2512 size parts are marked. For values which are integer numbers of milliohms, the marking is 4-character IEC62 code; e.g. "R002" for 2m , "R010" for 10m . For values including fractions of a milliohm the marking is 3 or 4-character code using "M" to indicate the decimal point, e.g. "M75" for 0.75m , "1M50" for 1.5m .
