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 re ow soldering; Green coating = IR re ow solder. Wave re ow - 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.
