The AEC-Q200 qualification (between -55 °C and 185 °C)
enables this series to be used for classical motor thermal
sensing applications (engine coolant, fuel sensor, TMAP for
manifold air pressure) as well as in HVAC applications.

DESCRIPTION
These negative temperature coefficient thermistors consist
of a mini-chip soldered between two AWG #32 PEEK
insulated silver plated NiFe alloy leads and coated with
black colored epoxy lacquer. High adhesive strength
between PEEK wire and encapsulating lacquer.
DESIGN-IN SUPPORT
Not intended for fluid immersed applications or continuous
contact with water or conducting liquids. See also
Environmental Conditions. Can be potted in suitable resins.
