WK73R Wide Terminal Thick Film Chip Resistors

KOA Speer WK73R Thick Film Wide Terminal Resistors feature a power rating range of 0.33W to 3.0W. The WK73R resistors can 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.
