Device with at least one ptc resistor

摘要

The device (10) has a ceramic positive temperature coefficient thermistor (30) dimensioned in such a manner that voltage drop does not exceed more than 40 voltage/millimeter over the thermistor, which is developed from multiple positive temperature coefficient thermistor elements (32) formed in rows and parallel. The thermistor elements exhibit a thickness of approximately 2 millimeter and breadth of approximately 6 millimeter. The thermistor elements are implemented as ceramic components with non-linear resistance characteristics.
