The Stackpole Electronics RMCF0603FT100K is a nonpolarized, 100 kΩ ±1%, 0.1 W thick-film surface-mount resistor in the 0603 (1608 metric) package, as reported by
Future Electronics and
JLCPCB. A common practical use for this resistance value is low-current logic biasing—particularly a weak pull-up or pull-down—with other applications including voltage dividers and RC networks when leakage and settling time permit.
