DIMENSIONS (Inches):
FUSE/PULSE APPLICATIONS:
SPP resistors normally fuse in less than one minute with five to ten times rated wattage depending on the range. By modifying the
windings, using a different wire size or type, they can be made to fuse much faster. On the other hand, by using larger wire diameters
and higher melt temperature alloys they can handle from five to fifty times overloads of film resistors depending on the range.
