The MM and SMM MELF resistors cylindrical design offers one of the largest effective resistive film areas of equivalent case size components. In addition, the resistors helical trimming cut avoids locally enhanced current densities. Thereby, a uniform and efficient distribution of the heat generated by the pulse load can be attained. Both MM and SMM MELF resistors offer best in class pulse load capability. The diagram here illustrates their destructive pulse load limit compared to thin and thick film chip resistors.
