Parts supplied under USA part numbering have the conductive element on the underside whilst those supplied under Marking European numbering have it on the upper side. These two The body protection is resistant to all normal cleaning solvents formats are functionally identical and interchangeable, and suitable for printed circuits 1206 and larger size chips are marked marking is always on the upper surface. R000. 0603 and 0805 sizes are not marked. Terminations The wrap-around copper terminations have an electroplated nickel barrier and solderable coating, which ensures excellent leach resistance properties and solderability.

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.
