ABSTRACT:
An electrical resistor having a resistance value and capable of withstanding high power surges, utilizing a thick film deposited on a substrate and trimmed with one or more cuts configured to maintain a level of current crowding while increasing the resistance value of the resistor. A surge resistor can be modified in a similar fashion.
