1/ The complete dash number will include two additional letters (indicated by **). The first additional
letter will indicate the inductance tolerance and the second additional letter will indicate the product
level (e.g., C, M, P, R, S) and will be added to the end of the dash number.
2/ The rated dc current is based on 90°C ambient temperature with a 35°C rise.
