Abstract
Thermistor chips are produced by preparing thermistor bodies each having outer electrodes formed on its end parts and dipping them in a solvent so as to melt away exposed surface portions of the thermistor body. In order to efficiently adjust their resistance values so as to produce thermistor chips with resistance values having only small variations from a target value, the resistance value between the outer electrodes are measured for each and they are divided into ranks according to the measured resistance values, and the dipping process is carried out differently for different ranks such that different amounts of the thermistor body material will be melted away.
Claims12
A thermistor chip comprising a thermistor body and outer electrodes on end parts of said thermistor body, said thermistor body having externally exposed surfaces which is not covered by said outer electrodes and is partially melted away by a solvent.
A method of producing thermistor chips, said method comprising the steps of:
- preparing thermistor bodies each having outer electrodes on end parts thereof;
- and
- dipping said thermistor bodies in a solvent to thereby melt away exposed surface portion thereof.
