... Leadless PTC thermistors In case of PTC thermistors without leads, soldering is restricted to devices which are provided with a solderable metallization. The temperature shock caused by the application of hot solder may produce fine cracks in the ceramic, resulting in changes in resistance. In addition, soldering methods should be employed which permit short soldering times. ...

... Conductive adhesion An alternative to soldering is the gluing of thermistors with conductive adhesives. The benfit of this method is that it involves no thermal stress. The adhesives used must be chemically inert and suitable for the temperatures arising at the surface of the termistor. 4 Clamp contacting Pressure contacting by springs is required for applications involving frequent switching and high turn-on powers ...

... When thermistors are sealed or potted, there must be no mechanical stress through differing ther- mal expansion in the curing process and during later operation. In the curing process the upper category temperature of the thermistor must not be exceeded also necessary to ensure that the potting compound is chemically inert. ...
