TYPICAL ASSEMBLY STYLES AND APPLICATIONS
Standard and custom assemblies are available in a variety of configurations. The choice of assembly style is dependent on the
application.
environment, mounting, time response and minimum dissipation constant.
The two factors which do vary considerably with assembly design are time constant and dissipation constant. The time constant will
typically be of greater duration in encapsulated thermistors. This is, of course, due to additional mass surrounding the thermistor
element; therefore, extending the thermal transfer time. Dissipation constant will also be greater in assemblies. The additional
housing mass serves well as a heat sink. Greater power is therefore required to induce self-heating.
Both time constant and dissipation constant will vary with the selected thermistor and housing. Heat transfer properties of the
housing, thermistor location, mass and wire type determine these constants. It is recommended to evaluate or consult the factory in
applications where T.C. and D.C. are critical.
