WK73R1ETTP1913F

KOA Speer WK73R Thick Film Wide Terminal Resistors feature a power rating range of 0.5W to 2.0W. The WK73R resistors are able to achieve a high power rating due to the reverse geometry design which provides greater heat dissipation. The resistors offer superior thermal shock characteristics, solder joint resistance, and excellent overall heat resistance with an operating temperature of -55�C to +155�C. The higher power rating of the WK73R components accommodates a desire for downsizing to allow for more available board space. KOA Speer WK73R resistors deliver high reliability with a low T.C.R. of �100ppm/�C or �200ppm/�C with resistance tolerances of 0.5%, 1%, and 5%. The reverse geometry components are RoHS Compliant and AEC-Q200 qualified. The WK73R are ideal for use in automotive power supplies (DC-DC conversion), ECU, and industrial power supplies.
