Notes:
1.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. 2Non-standard resistance values available (contact factory). For resistance values above 20 mΩ, please refer to our LRC / LRF series.
