Linear positive temperature coefficients:
LP & MLP temperature sensitive resistors feature linear positive
T.C.’s in a wide range of R/T slopes. The series was developed as
a low cost substitute for wirewound sensors. Various temperature
coefficients are obtained by adjusting the film composition. LPT
features platinum film for improved linearity, interchangeability and
+300°C operating temp. Small sizes result in fast response
times, typically 6 seconds for LP/MLP12 & LPT, 9 seconds for
LP/MLP25 (in still air).
