For high pulse load applications, the resistor’s pulse load capability is essential. Carbon film MELF resistors are the pulse load champions of SMD film resistors, as they combine the most important characteristics that support high pulse load capability: the pulse resistant cylindrical design, offering the largest effective film area; the helical trimming cut, avoiding locally enhanced current densities; and the carbon film material, with its unrivaled thermal stability. The diagram here illustrates the maximum single pulse load capability of carbon film MELF resistors compared to metal film MELF resistors with typical specification.
