PTC-resistor Temperature Sensors
PTC-Resistor Temperature-Sensors MINIKA®
to DIN 44 081 and DIN 44 082
PTC-resistor temperature sen-
sors (also called PTC-resistors
or thermistors) are temperatur
dependent semiconductor resis-
tors whose main function is to
alter their electrical resistance
drastically when their body tem-

temperature NAT (TNF)
PTC-resistors are used principally to protect windings
inelectromotorsortransformersagainstexcesstempe-
rature. They also find application in machines, tooling
machines especially machine bearings and controlling
the temperature of power semiconductors.
General
PTC-resistortemperaturesensorsareparticularlysuited
to this purpose due to their precise response range
combined with small dimensions and minimal thermal
inertia at low cost.
