Note:
1. 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.
2. Full AEC-Q200 qualification applies to ohmic values
≥R01.
