Notes:
1 Non-standard resistance values available (contact factory). For resistance values above 20 mΩ, please refer to our LRC / LRF / LRMA series. 2 Black
coating = wave or IR reflow soldering; Green coating = IR reflow solder. Wave reflow - solder mask must match the W and D dimensions on page 2 of data
sheet. 3 Package sizes 2010 and 1206 with the green coating are uncoated on the top surface and unmarked for resistance value.
