Pb-free 1206 size chips supplied under USA part conductive element on the underside, whilst all other parts have numbering are marked LRZ. All other parts are marked R000. it on the upper side. These two formats are functionally identical and interchangeable, and marking is always on the upper surface. Terminations The wrap-around copper terminations have an electroplated nickel barrier and solderable coating, which ensures excellent leach resistance properties and solderability. Chips can withstand immersion in solder at 260C for 30 seconds and are suitable for reflow or wave soldering processes.

AEC quali cation based on testing of structurally similar LRF Series low value chip resistors, of which LRZ is the zero-ohm version. R measurements are not applicable to the zero-ohm version. 2. Although 2010 and 2512 sizes have passed temperature cycling and thermal shock, it is in general not recommended that ceramic chips this large be used on FR4 in a severe temperature cycle environment due to the possibility of solder joint fatigue. 3.
