Stackpole RWT Thermal Fusing Vertical Mount Resistors

Stackpole RWT thermal fusing resistors combine a wirewound ceramic element and thermal fuse in a ceramic case for vertical through-hole mounting. All listed parts have ±5% tolerance. Standard A-fuse versions use a 250 V, 2 A fuse with a rated functioning temperature of 142 °C and resistor TCR of ±200 ppm/°C.

The element power rating is distinct from the lower element-plus-fuse assembly rating; both apply at 70 °C. RWT2 is 2 W for the element and 1.5 W for the assembly; RWT5 is 5 W and 1.6 W. The HT variant retains its encoded resistance and tolerance, with unverified power, TCR, and thermal-fuse details left unspecified. Consult the datasheet for selection and operating limits.
